Question 1:

Human activities that causes accelerated eutrophication which is excess amounts of nitrogen and
phosphorus into water include the use of agricultural fertilizers. Others include sewage and
aquaculture which is the growing or farming of fish and aquatic plants, which in turn has a huge
impact on aquatic life as eutrophication can have serious effects that block light from getting into
the water due to algal blooms which harms the plants and animals that need it to survive.

If there is also a lot of algae that grows on top of the water, it prevents oxygen from entering the
water making it hypoxic and creating zones when no aquatic life can survive and thus in the future it
will cause big problems for the ecosystem which depends on that body of water.

deepest parts leaving all the shallower areas dry.
