Question

Choose the correct answers from the alternatives given .
If evolution occurs, we would expect different biogeographical regions with similar environments to

• A. Have plants and animals that have similar adaptations
• B. All contain the same mix of plants and animals
• C. Each have its own specific mix of plants and animals
• D. Both (a) and (C)

Answer 1

The correct option is D Both (a) and (C)

It is necessary for organisms to adjust to the conditions and environment they live in. The special characteristics possessed by plants and animals that enable them to successfully survive in a particular environment is the adaptation. Those organisms that share the same biogeographical regions with similar environments need to adopt similarly for their survival. For example, those organisms that live in seawater needs to adopt a special mechanism to regulate their temperature, osmolarity, and oxygen supply.

Since each habitat has several species that adapted for their survival in that particular habitat, each habitat has its own specific mix of plants and animals.

So, the correct option is 'Both (a) and (c)'.
