https://padlet.com/jessika_dorcas/kfee2zi0pi7j How does food web complexity affect the biodiversity of an ecosystem? en-us 2018-10-01 19:16:52 UTC 2018-10-03 14:21:33 UTC hello@padlet.com https://padlet-assets.s3.amazonaws.com/icons/Xmastree.png https://padlet.com/jessika_dorcas/kfee2zi0pi7j/wish/288589017 C-When the complexity is very high in an ecosystem, the biodiversity goes down. When the complexity is very low the biodiversity also goes down. To get the highest biodiversity you must have a medium complexity.

E- 1) When We made our ecosystem very simple one of our organism died on day 23. This made our ecosystem less biodiverse because one of the few organisms that were associated with the ecosystem got wiped out. 

E-2 When we made our ecosystem very complex and the omnivores were both wiped out by day 100.

E-3 When we adjusted the complexity of the food web to a medium level, we got our highest results from the biodiversity graph. More of the organisms had a healthier population with this type of food web.

R- When using the simulation, there became a clear connection between the food web complexity and the biodiversity of the ecosystem. The food web cannot be too complex or too simple, it has to be the perfect middle point in order to sustain high biodiversity.]]> 2018-10-03 13:01:47 UTC https://padlet.com/jessika_dorcas/kfee2zi0pi7j/wish/288589017 https://padlet.com/jessika_dorcas/kfee2zi0pi7j/wish/288589940 C - The complexity of the food web decreases the biodiversity of the ecosystem.
E - 
1. The more complex the food web got, the lower the population sizes of everything except producers. 
2. Also, the less complex the food web, the less fluctuation there is in population size, so it creates a stable environment. 
3. In the more complex food web, multiple species started dying out, making the ecosystem completely unsustainable and the species richness decreased drastically.
R - Our reasoning suggests that the relative abundance and species richness decrease with a more complex food web, which are the primary measures of biodiversity. The more complex the food web is, the less stable it will be, so it is more beneficial to the ecosystem to have a simple food web to stabilize the environment.]]> 2018-10-03 13:03:21 UTC https://padlet.com/jessika_dorcas/kfee2zi0pi7j/wish/288589940 https://padlet.com/jessika_dorcas/kfee2zi0pi7j/wish/288590057 C: When the food web is too complex the biodiversity decreases, when the food web is too simple the biodiversity also decreases. 
E: 
1) When all components turned on, the omnivores disappear and the herbivores decrease greatly. Many species died out, decreasing diversity.
2) When the food web is too simple, only one or two species is able to survive, decreasing diversity.
3) When put into a middle ground species are able to survive and flourish, increasing and making a stable amount of diversity.
R: Biodiversity affects an ecosystem greatly. When the ecosystem is too biodiverse it fails, and if the ecosystem is lacks too much in diversity it also fails. When the Ecosystem has a middle ground of diversity, it flourishes.]]> 2018-10-03 13:03:35 UTC https://padlet.com/jessika_dorcas/kfee2zi0pi7j/wish/288590057 https://padlet.com/jessika_dorcas/kfee2zi0pi7j/wish/288590242 C-The complexity of the food web decreases the biodiversity in an ecosystem. 
E- 1.When you turn on all of the interactions and make the food web very complex, the animal population decreases and the plant population increases. 
E-2. When the food web is less complex, the environment stabilizes because the population stays the same because there are not as many variables. 
E-3. When the complexity of the food web is high, some species of animals are removed from the environment. This shows that the biodiversity is decreasing as the complexity of the food web increases.
R-Our reasoning states that as the complexity of the food web increases, the biodiversity of the ecosystem decreases. It does this because the stability is lower, and more species of animals cannot survive. In conclusion the more simple the food web is, the more stable it is for the environment. ]]> 2018-10-03 13:03:55 UTC https://padlet.com/jessika_dorcas/kfee2zi0pi7j/wish/288590242 https://padlet.com/jessika_dorcas/kfee2zi0pi7j/wish/288591805 C- When there is a more complex food web, the biodiversity increases.
E-
1. As the food web got more complex, certain organisms populations decreased. When the secondary consumer ate more primary consumers, it forced them into extinction. 
2. As it gets more complex, there are more foods organisms can eat, so populations numbers are fluctuating constantly,
3. In a less complex food web, it is stable because each organisms have certain things they eat, so nothing changes.
R- Our reasoning is that with a complex food system, more organisms are eating other organisms, causing it to more complex, and less stable. But with a simple food web, everything is balanced and the ecosystem maintains stability. 

Reply to Maddie and Grace- We believe that when the food web is more complex, there is more diversity, because organisms are eating more organisms and the ecosystem is become more diverse.

E:
1. When there is more complexity, there is an increase in competition among species. Because of that, the biodiversity decreases.
2. When there's less complexity, the population remains fairly stable, resulting in more biodiversity.
3. With a medium amount of complexity, the biodiversity of the ecosystem stays relatively the same. 
R: The more complex it gets the less stable each species gets resulting in a lower rate of survival.

E- Most populations don't decrease with less complexity in the food web. Biodiversity neither decreases nor increases with the less complex food web. After 100 days, Plant A levels out at about 5000, whereas all the other populations drop below 1800 and level out. 3 species die out in the more complex food web, but everyone survives in the less complex one.
R- The less complex food web proved to have higher numbers in each population, but the more complex food web had many populations drop off drastically or even die out. ]]> 2018-10-03 13:08:56 UTC https://padlet.com/jessika_dorcas/kfee2zi0pi7j/wish/288592850 8584461 https://padlet.com/jessika_dorcas/kfee2zi0pi7j/wish/288592917 C: When the complexity of the food web increases, so does the biodiversity. 
E: 
1. The complex food web has higher populations of each species which increases the biodiversity 
2. Compared to the simple food web, each species is more common and abundant in the complex food web 
3. In simple food webs with less populations, the species are more likely to be harmed by change and decrease in population. 
R: Because complex food webs have a higher population abundance and are more sustainable to change, biodiversity increases when the food web is more complex. 

Reply to Mara and Andrew: 
We think that the food web complexity increases biodiversity not decrease. In our experiment, When we increased complexity, the populations increased and when there was no complexity, many of our species' populations decreased. ]]> 2018-10-03 13:09:05 UTC https://padlet.com/jessika_dorcas/kfee2zi0pi7j/wish/288592917 https://padlet.com/jessika_dorcas/kfee2zi0pi7j/wish/288593998 C - The more complex the food web, the more biodiversity starts to decrease. Also, if the web is too simple, it causes drops in biodiversity as well. 

E - (1) When our food web was very complex, two species completely died off, while all species decreased in number. (2) When too simple, two species also died off, but all other species remained stable. (3) When the food web had a fair balance between complex and simple, all species started by fluctuating, but ended stable. 

R - Through using food web simulators, we found evidence that shows that a food web has to have a balance within to maintain a stable level of biodiversity. When you become too complex or simple, biodiversity decreases greatly]]> 2018-10-03 13:10:31 UTC https://padlet.com/jessika_dorcas/kfee2zi0pi7j/wish/288593998 https://padlet.com/jessika_dorcas/kfee2zi0pi7j/wish/288609031 Responding to...Grace Martinez and Maddie Nusbaum

We agree that as the food web gets more complex, the biodiversity of the ecosystem decreases. We think that you made a good point by saying that there is less fluctuation in the population size of an ecosystem with less complexity.]]> 2018-10-03 13:31:36 UTC https://padlet.com/jessika_dorcas/kfee2zi0pi7j/wish/288609031 https://padlet.com/jessika_dorcas/kfee2zi0pi7j/wish/288613463 We agree with their CER because when a food web becomes more complex, the biodiversity will decrease. When we were doing the simulation at least one of the organisms would die. When we created a simple food web only a few species would remain]]> 2018-10-03 13:37:44 UTC https://padlet.com/jessika_dorcas/kfee2zi0pi7j/wish/288613463 https://padlet.com/jessika_dorcas/kfee2zi0pi7j/wish/288618096 2018-10-03 13:44:07 UTC https://padlet.com/jessika_dorcas/kfee2zi0pi7j/wish/288618096 https://padlet.com/jessika_dorcas/kfee2zi0pi7j/wish/288618102 C- The more complex a food web is, the less biodiverse in an ecosystem becomes. However, when a food web is too complex, the biodiversity decreases as well. 
E: 1- When all components to the simulation were turned on, and all organisms were generalists, only a few species survived, greatly decreasing biodiversity. This was because resources depleted very early on and other organisms were affected by the decline of their food source. 
2- When the simulation was too simple, the resources depleted once again, decreasing biodiversity. The organisms eventually ran out of things to eat because their food source had depleted. 
3- When the simulation was not too simple and not too complex, the biodiversity was generally stable and the biodiversity did not decrease too much. This was because some of the organisms were generalists and some were specialists, allowing variation within the ecosystem and allowing different organisms to thrive. 
R- Relative abundance relates to species richness because when the species richness is very high, relative abundance is low which causes the biodiversity to decrease over time. However, when species richness is low relative abundance is high; but over time, resources will start to deplete and biodiversity will decrease. We conclude that if a food web is too complex or too simple, the biodiversity will decrease.
