Question

5. Explain the problem if too much nitrogen enters an aquatic ecosystem.
6. Explain the statement "Nutrients do not flow in one direction in the ecosystem, they recycle through the ecosystem."

Answer 1

Answer:

5)Problems with excess levels of nitrogen in the environment

Excess nitrogen can cause overstimulation of growth of aquatic plants and algae. Excessive growth of these organisms, in turn, can clog water intakes, use up dissolved oxygen as they decompose, and block light to deeper waters.

6) This statement means that the flow of nutrients is not unidirectional in an ecosystem, i.e. the nutrients do not flow in one direction. ... Example: Nutrients that are passed on from the plants to herbivores and then to other organisms are recycled back into the atmosphere after that organism dies.

Answer 2

Answer: to 5

Explanation: Too much nitrogen and phosphorus in the water causes algae to grow faster than ecosystems can handle.
