Answer:
They adapt and survive because of Natural Selection
Explanation:
The sea animals die off if they cannot survive under certain conditions so they adapted to having eyes that can see, and other necessary survival tools for the bottom of the deep sea.
The answer is
"Ecology".<span>As various other researchers, Ecologists, regularly utilize
models to help comprehend complex issues. Ecological systems are frequently
demonstrated utilizing PC simulation. PC simulations can consolidate a wide
range of factors and their effects. This is one reason they are valuable for modeling
ecology. PC simulations are likewise working models, so they can demonstrate
what may occur in ecosystem after some time. For instance, simulations of
global warming have been utilized to make expectations about future
atmospheres. And field study is the key element to investigate ecological
systems based on which at times are prepared the computer simulations.</span>

The parasympathetic nervous system is characterized by the location preganglionic neurons and the short postganglionic axons near the organs they innervate. The preganglionic neurons would originate in the spinal cord or the brainstem while the postganglionic neurons would lie outside the CNS.
