Fluctuations in the phosphorus cycle in aquatic ecosystems

a. can lead to changes in the growth rates of aquatic populations

Explanation:

The rise in phosphorus quantity within the aquatic scheme can increase the quantity of protoctist among that scheme. Once the quantity of protoctist is raised, the aquatic organisms can have loads of food supply which is able to increase the expansion rate among their population.

a. decomposes use carbon from dead organisms as fuel for cellular respiration, returning carbon dioxide back into the atmosphere.

the "dirty dozen" chemicals banned in an international treaty are formally known as persistent organic pollutants, or pops. the united nations environment program provided this background on what they are and what they can do to humans and wildlife.
