Answer:

B. Organisms in each ecological system have evolved in that system and have adaptations suited for that environment.

Explanation:

According to natural selection theory, organisms need to continuously adapt and evolve within an environment or risk being wiped away from that environment.

Organisms that are not able to adapt to an environment are gradually replaced by those that have the capability to adapt and survive in that environment.

Those that are able to survive go ahead to reproduce and give rise to offspring with inherent ability to survive while those that cannot survive die off.

The correct option is B.

Answer:

B. Organisms in each ecological system have evolved in that system and have adaptations suited for that environment.

Explanation:

Every organism lives in a habitat, within which it lives in an ecosystem best suited for its need. An organism needs food, water and a favorable weather to live. For an organism to survive in an ecosystem, it needs to adapt to the conditions in that ecosystem, else it dies. Therefore, different types of organisms in different systems will have varying characteristics.

This is linked to Charles Darwin’s theory of evolution which implies that all organism in an ecological system evolve heritable traits suited for their environment.
