Question

Which of the following statements regarding aquatic ecosystems is

incorrect?

Estuaries are considered fish nurseries where fish lay their eggs and hatchlings
spend the first year of their lives.

The intertidal zone can be submerged and exposed depending on the tide.

Lentic and lotic ecosystems are characterized by high nutrient levels and
fluctuating salinity.

O Aphotic zones do not receive enough sunlight to support photosynthetic
organisms.

Answer 1

The incorrect statement is that lentic and lotic ecosystems are characterized by high nutrient levels and fluctuating salinity. Instead, these freshwater ecosystems typically have constant salinity levels and do not experience the salinity fluctuations seen in estuaries.

Step-by-step explanation:

The statement regarding aquatic ecosystems that is incorrect is: Lentic and lotic ecosystems are characterized by high nutrient levels and fluctuating salinity. Lentic (still water) and lotic (flowing water) ecosystems, such as lakes and rivers, do not typically have fluctuating salinity levels. They have more constant salinity compared to estuarine environments where fresh water mixes with salt water causing rapid changes in salinity. Estuaries are indeed known as nurseries for fish, where many species lay their eggs, and juveniles spend their early life stages. The intertidal zone is indeed affected by the tides, being submerged and exposed as the tide goes in and out. The aphotic zones are parts of the ocean where sunlight does not penetrate, making it impossible for photosynthetic organisms to thrive there.

Answer 2

All are correct, bit I believe this to be most accuraye: Estuaries are considered fish nurseries where fish lay their eggs and hatchlings

spend the first year of their lives.
