Question

which statement describes competition within a population?
several killer whales migrate to a new location.
two male sea horses fight to win over a female.
several elk travel together to find and share water.
different kinds of garden plants take in water from the soil.

Explanation:

Competition within a population involves individuals of the same species competing for limited resources (including mates). Let's analyze each option:

1. Killer whales migrating is movement, not competition.
2. Two male sea horses (same species) fight for a female (mate competition within a population).
3. Elk sharing water is cooperative behavior, not competition.
4. Different garden plants are different species, so this is interspecific competition, not within a single population.

Answer:

B. Two male sea horses fight to win over a female.
