Question

Why do populations in the deep sea tend to have longer lifespans than those in higher layers

Answer 1

Answer:

The deep sea environment is more stable and is less impacted by detrimental events and phenomena such as changes in temperature changes and intense storms.

Explanation:

In 2018, researchers analyzed over 200 species inhabiting in both deep sea and near the sea surface across the world and found that deep sea organisms are more likely to have longer lifespans.

According to their results, the environmental conditions that characterize the deep sea is more stable, enabling deep-dwelling organisms to have longer lifespans. Moreover, deep sea organisms are more protected from events and phenomena that affect shallow-water species, such as changes in temperature and intense storms.
