Question

multiple choice 1 point

1. which best determines the chemistry of an aquatic ecosystem?

amount of salts, nutrients and dissolved oxygen
biotic and abiotic factors in the water
amount of rainfall received
number of organisms present in the aquatic ecosystem

Explanation:

The chemistry of an aquatic ecosystem is determined by the amounts of salts, nutrients, and dissolved oxygen present in the water. These chemical - related factors play a crucial role in the chemical processes and balance within the ecosystem. The number of organisms affects the biology of the ecosystem, rainfall affects water quantity and some physical aspects rather than chemistry directly, and biotic and abiotic factors is a broad term that is not as specific as the chemical components mentioned in the correct option for determining chemistry.

Answer:

Amount of salts, nutrients and dissolved oxygen
