Answer

Brief Explanations:

The model shows natural - selection with some individuals not surviving due to unfavorable traits in changing conditions and survivors reproducing. It does not show that mutations occur in response to environmental changes to help organisms survive. Mutations are random events, not directed responses to environmental needs. Option A is not shown but not refuted either. Option B is supported as change in conditions affects survival. Option C is clearly shown as survivors reproduce.

Answer:

D. Changes occur in the environment and mutations occur to help organisms survive.
