What is Eutrophication?

• It is low nutrient rich waters which causes dense growth of plants.

• It is excessive richness of nutrients in a lake or other body of water; cause of death of animal life due to lack of oxygen

• It is an animal consuming another animal in the food web.

• It is bacteria in the soil fixing nitrogen allowing animals to intake nitrogen.

What is Deforestation?

• The intentional clearing of forested land or related ecosystem.

• The growth of plants in a forest causing increased oxygen in the air.

• The growth of shrubs and conifers towards a climax community.

• The increase in food in the food web due to an increase in biodiversity.
