Question

which factors may contribute to the extinction of a species? check all that apply. more individuals fighting over the same resources fewer individuals fighting over the same resources the loss of the environment in which an organism’s needs are met the gain of an environment in which an organism’s needs are met the lack of predators in an area the introduction of new predators into an area

Explanation:

• More individuals fighting over same resources: High intraspecific competition leads to insufficient resources for survival/reproduction, reducing population size over time.
• Loss of critical environment: A species' native habitat provides food, shelter, and breeding sites; losing it removes the conditions needed for survival.
• Introduction of new predators: Non-native predators often have no natural checks, and native species lack defenses against them, leading to rapid population decline.

The other options support species survival (fewer competitors, new suitable habitat, lack of predators) rather than contributing to extinction.

Answer:

• more individuals fighting over the same resources
• the loss of the environment in which an organism's needs are met
• the introduction of new predators into an area
