Which statement about how organisms depend on abiotic factors in an aquatic ecosystem is not true?a. most living organisms can survive in environments with several different temperature and salinity levels
b. both aquatic plants and animals depend on dissolved oxygen for respiration
c. abiotic factors that impact an aquatic ecosystem include temperature, salinity, flow, and dissolved oxygen in the water
d. abiotic factors of an aquatic ecosystem determine what kind of life can exist in that environment

Answers

The answer is a. most living organisms can survive in environments with several different temperature and salinity levels.

Aquatic plants and animals depend on dissolved oxygen for respiration. The other abiotic factors that impact their life in an aquatic ecosystem are temperature, salinity, and flow and they determine the quality of their life. It is not true that most living organisms can survive in environments with several different temperature and salinity levels. On the contrary, a few species can live in environments with several different temperature and salinity levels, for example, some bacteria. The most organism can survive in a specific range of abiotic factors.

Answer:

most living organisms can survive in environments with several different temperature and salinity levels

The vultures do not have hair on their heads? explain
