Answer to question no. 1:
A forest is at its young stage when it’s hardly touched by human or any external or harmful intervention, leaving it as natural as it is. That means it is filled with healthy vegetation, saplings everywhere, mature trees, vines and shrubs.
In this very rich forest environment, many species of animals thrive. Most of them would be endangered species of migratory songbirds, mammals like white-tailed deers or rare insects.
Answer to question no. 2:
Crocodiles are able to adapt in most areas and can live for a long period of time due to several factors:
1) They are cold-blooded. A cold-blooded animal would have very slow metabolism so they can live without food for many months. One big meal can keep them full for a long time.
2) They can survive both on land and water.
3) Just like mammals, the crocodile’s heart has four chambers that allows them to control their body temperature at a constant level. This is why they are able to adapt in many places.
4) Crocodiles have strong senses which makes them good hunters / predators
a. Sense of sight: they can see underwater and have night vision
b. Good sense of smell
c. Sensory buds in their jaws that help them detect vibrations and movements
