Question

Imagine you are a fish stranded in a small pool of water on land. The pool of water occasionally almost dries up. What challenges does life on land present? What are 2 key changes in vertebrate evolution from aquatic to terrestrial habitats?

Answer 1

Step-by-step explanation:

The facts from the scientific studies revealed that life originated in the aquatic condition and one of the eukarya evolved into the fish.

The fish is an aquatic organism and if the source of water dries up due to certain factors then the fish will have to adapt to survive on the terrestrial habitat.

1. The challenges that the fish will face surviving on land will be movement, breathing, feeding, and reproduction.

2. So this will lead to changes in the fish which are that for movement fish will develop limbs, for feeding fish will develop jaws, for reproduction fish instead of laying eggs will evolve placenta which will help nurture young in the womb.
