Question

a population of beetles has both light - colored and dark - colored individuals. the environment becomes darker due to pollution. which beetle is more likely to survive in this updated environment?

• light - colored beetles
• dark - colored beetles
• both beetle colors will equally survive
• only the largest beetles

Explanation:

This is a question about natural selection. In a darker environment, dark - colored beetles are better camouflaged from predators compared to light - colored beetles. Camouflage helps organisms avoid being detected, so dark - colored beetles have a higher chance of survival as they blend in with the new, darker environment. Light - colored beetles would stand out and be more likely to be preyed upon. The size of the beetles is not related to survival in this context of environmental color change.

Answer:

B. Dark - colored beetles
