In what way does the endocrine system cause homeostasis
kap26 [50]

Answer:

Explanation:

The endocrine system plays an important role in homeostasis because hormones regulate the activity of body cells. The release of hormones into the blood is controlled by a stimulus. For example, the stimulus either causes an increase or a decrease in the amount of hormone secreted. Then, the response to a stimulus changes the internal conditions and may itself become a new stimulus. This self-adjusting mechanism is called feedback regulation.

Degger [83]

Answer:

For one thing, there's lots more of it. There are many more environmental niches to be occupied in salt-water bodies, and importantly, they're all connected, making it easier for species to migrate and adapt to new habitats. Conversely, fresh-water habitats are often more isolated, confining species to a single habitat and decreasing the likelihood that they'll be able to migrate and adapt.
