How can humans changing a wetland environment so they can build there affect the wetland ecosystem?
What is by filling the wetland ecosystem, people destroy a natural environment for many plants and animals. This leads to changes that affect entire specials, many of which cannot survive the wetland environment.

How does the frog's color help it survive?
What is the frog's color helps it hide on the ground and in plants from its predators?

Why do some animals of the same species, that live in different places, have different appearances?

How does a drought affect the habitat and how a species can survive this sudden changes?
What is a drought can affect the plants and animals that are living in that environment. It can also lead to species having to leave to find a new habitat in order to survive. If a species can not leave, it can lead to adaptations or possibly extinction.

What will happen if a plant or animal cannot adapt to harmful changes in its ecosystem?
What is they must migrate to another place? If it can not migrate to another place, the population will decrease, with a chance of extinction.
