Question

question 6 of 10
why are certain traits adaptations in one ecosystem, but not in another?
a. organisms lose adaptations when they migrate.
b. ecosystems can have different conditions.
c. all ecosystems have the same amount of competition.
d. organisms can learn new adaptations.

Explanation:

Adaptations are traits that help an organism survive and reproduce in its environment. Different ecosystems have different conditions (e.g., temperature, food sources, predators). A trait that is useful in one set of conditions (e.g., thick fur in a cold ecosystem) may not be useful in another (e.g., a hot ecosystem). Option A is incorrect because adaptations are not simply "lost" when migrating - evolution is a long - term process. Option C is wrong as ecosystems vary greatly in competition levels. Option D is about learning, but adaptations are mainly through evolution (not immediate learning in the context of this question).

Answer:

B. Ecosystems can have different conditions.
