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 occurs when members of the same species compete for limited resources (including mates).

• Migration is movement, not competition.
• Elk sharing water is cooperation, not competition.
• Different garden plants are different species, so this is interspecific competition, not within a single population.
• Two male sea horses are the same species competing for a mate, which fits intraspecific (within population) competition.

Answer:

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