Describe the effect of Eutrophication on the aquatic animals in the lake. by Tanveer Fatima https://padlet.com/tanveerfakn/sand Qs. en-us 2017-03-12 04:39:34 UTC 2023-02-27 09:42:37 UTC hello@padlet.com Shaikha 🌸 https://padlet.com/tanveerfakn/sand/wish/159469354 Eutrophication can have serious effects, like algal blooms that block light from getting into the water and harm the plants and animals that need it.
If there's enough overgrowth of algae, it can prevent oxygen from getting into the water, making it hypoxic and creating a dead zone where no organisms can survive.]]> 2017-03-12 04:44:19 UTC https://padlet.com/tanveerfakn/sand/wish/159469354 Shyam🐘 https://padlet.com/tanveerfakn/sand/wish/159469671 1. Algae growing at the surface of the water can suddenly multiply very quickly
2.the execessive algae growth in a lake or pond appears as a green blanket 
3. Other organisms that eat the algae can multiply numbers as well. ( first time I didn't copy from anyone) 💕]]> 2017-03-12 04:45:13 UTC https://padlet.com/tanveerfakn/sand/wish/159469671 Mariam El-Tal https://padlet.com/tanveerfakn/sand/wish/159469674 The effects are the following:
» Lakes become covered with algae (bright green). Which blocks sunlight, prevents photosynthesis, and causes death of plants.
» Fish and other sensitive organisms might die from the lack of dissolved oxygen.
» Organisms that eat algae grow in numbers.
» Algae releases toxins that may be harmful to plants.

Excessive richness of nutrients in a lake due to run-off from the land , causes dense growth of plant-life 
Harms plants and animals by blocking sunlight and oxygen.
Algae grow rapidly in lakes due to eutrophication which block the sunlight and algae prevent sunlight from reaching the bottom of the lake causing sunlight-dependant plants and other organisms to die. The decaying of large amount of plants and other animals decrease the amount of the oxygen in the lake causing many fish and other animals in the lake to die.]]> 2017-03-12 04:45:22 UTC https://padlet.com/tanveerfakn/sand/wish/159469679 Fatema🔪 https://padlet.com/tanveerfakn/sand/wish/159469680 1. Species diversity decreases and the dominant biota changes

2. Plant and animal biomass increase

3. Turbidity increases

4. Rate of sedimentation increases, shortening the lifespan of the lake

5. Anoxic conditions may develop

Because of the high concentration of organisms in a eutrophic system, there is often a lot of competition for resources and predator pressure. This high degree of competition and the sometimes-high chemical or physical stress make high the struggle for survival in eutrophic systems. As a result the diversity of organisms is lower in eutrophic than in oligotrophic systems.

Usually, nature does a pretty good job of providing just the right amount of nutrients, because too many or too few can cause problems. This is especially true in aquatic ecosystems because they are so dynamic. When too few nutrients are present, the water is oligotrophic. It makes sense that when there is not enough nutrition available for the variety of organisms living in an aquatic environment, serious problems will arise. 

However, problems can also arise when the aquatic system has an overabundance of nutrients. When this happens we get eutrophication. A eutrophic stream, river or lake occurs when too many nutrients, like nitrogen and phosphorous, are present, usually as a result of runoff from the surrounding land. Algae, plankton and other microorganisms love these types of nutrients, and when they are plentiful, these aquatic organisms can take over. When a lake, river or other aquatic system becomes eutrophic, it can have serious negative effects on other organisms like fish, birds and even people. But first, let's look at what causes eutrophication.

Still, human activities have sped up the degree and rate of eutrophication through both point-source and non-point source discharges of the chemical nutrients (phosphates and nitrates) into aquatic systems. Some of the consequences of eutrophication include destruction of aquatic systems and reduction in water quality.]]> 2017-03-12 04:47:38 UTC https://padlet.com/tanveerfakn/sand/wish/159469736 Muna https://padlet.com/tanveerfakn/sand/wish/159469805 2017-03-12 04:48:11 UTC https://padlet.com/tanveerfakn/sand/wish/159469805 Suhaila https://padlet.com/tanveerfakn/sand/wish/159469819 The main effects caused by eutrophication can be summarized as follows [3]:
