Population: a group of organisms of the same species, who live in the same area at the same time.
Autotrophs: absorb carbon dioxide, water, and inorganic nutrients such as nitrates from the abiotic (non-living) environment and use them to synthesize all the carbon compounds that they need; light is used as an external energy source.
Heterotrophs: cannot make carbon compounds that they need and instead obtain them from other organisms.
Mixotrophic: can survive either making their own nutrients or obtaining it from others.
Saprotrophs: obtain organic nutrients from dead organisms by external digestion.
Consumers: feed on living organisms by ingestion.
Detritivores: obtain organic nutrients from detritus (dead material from living things) by internal digestion.
Relationships: both benefits OR one benefits the other has no gain or loss OR one benefits while one is harmed.
Community: a group of populations of different species living together and interacting with each other in an area.
Ecosystem: a community formed by its interactions with the abiotic environment.
Food web: complex network of feeding relationships in a community.
Mesocosm: a small experimental environment area set up in an ecological research programme.
Quadrat: a square sample area used in ecological research.
Quadrat Sampling: repeatedly placing a Quadrat frame, random positions in habitat and recording the number of organisms.]]> 2016-10-12 12:26:56 UTC https://padlet.com/fayealwadi1/7eccvqxa6f0a/wish/130095721 fayealwadi1 https://padlet.com/fayealwadi1/7eccvqxa6f0a/wish/130113344 - Species will reproduce in their population, but have the capacity of doing the same in other populations as long as its the same species, their offspring will be fertile in most cases. ]]> 2016-10-12 13:21:18 UTC https://padlet.com/fayealwadi1/7eccvqxa6f0a/wish/130113344 fayealwadi1 https://padlet.com/fayealwadi1/7eccvqxa6f0a/wish/130115759 - Two main modes of nutrition: Autotrophs and Heterotrophs.
- Heterotrophs eat Autotrophs in order to get the nutrients that they can't produce themselves. 
- Majority of plants are Autotrophs; only 1% are Heterotrophic. 
- Any species getting their supply of carbon compounds from any other species is known as a Heterotrophs, regardless of the species. "We cannot assume that a plant or alga is autotrophic- not all are."]]> 2016-10-12 13:27:39 UTC https://padlet.com/fayealwadi1/7eccvqxa6f0a/wish/130115759 fayealwadi1 https://padlet.com/fayealwadi1/7eccvqxa6f0a/wish/130120840 - A Positive Association is when two species are always seen together (I.e.humans and dogs), and a Negative Association is when two species are NEVER seen together (I.e. a spider and a fly).]]> 2016-10-12 13:40:00 UTC https://padlet.com/fayealwadi1/7eccvqxa6f0a/wish/130120840 fayealwadi1 https://padlet.com/fayealwadi1/7eccvqxa6f0a/wish/130126704 - Populations live together in order to survive.
- The interaction between populations is important for harmony and trophic nutrition (sad, but that's how the world works).
- Ecosystems allow population to interact with their abiotic surroundings.
- The relationships between biotic (living) and abiotic environments are vital for chemical and nutrient recycling in the Ecosystem - which have the potential to be around for a long time, as long as the nutrients keep recycling, have a constant supply of energy - the continue as long as they can. ]]> 2016-10-12 13:54:19 UTC https://padlet.com/fayealwadi1/7eccvqxa6f0a/wish/130126704 fayealwadi1 https://padlet.com/fayealwadi1/7eccvqxa6f0a/wish/130134798 - Test environments allows a visual of incite into an ecosystem.
Vitals:
+ Autotrophs produce carbon compounds and oxygen.
+ Saprotrophs decompose dead organic matter and recycle nutrients.
+ Consumers and detritivores (not as vital) are a usual part of ecosystems. ]]> 2016-10-12 14:13:23 UTC https://padlet.com/fayealwadi1/7eccvqxa6f0a/wish/130134798 fayealwadi1 https://padlet.com/fayealwadi1/7eccvqxa6f0a/wish/130140362 - If the presence or absence of two species is recorded in a large number of quadrats, a chi-squared test for association between species can be performed.]]> 2016-10-12 14:27:14 UTC https://padlet.com/fayealwadi1/7eccvqxa6f0a/wish/130140362 fayealwadi1 https://padlet.com/fayealwadi1/7eccvqxa6f0a/wish/130142429 - The Quadrat is used to record the absence and presence off each species of interest inside of it or record the number of individuals.
