Question

which situation would encourage competition?
a dry season results in additional open caverns for foxes to use as shelters.
a warm, sunny season, results in a bloom of algae growth in a fish habitat.
a long, wet season results in additional earthworms in a robin habitat.
the amount of vegetation decreases due to a drought in a rabbit habitat.

Explanation:

Competition among organisms occurs when a shared limited resource becomes scarcer, forcing individuals to compete for access.

• Option A: More shelters mean fewer competition for this resource.
• Option B: More algae (food for fish) reduces competition.
• Option C: More earthworms (food for robins) reduces competition.
• Option D: Less vegetation (the main food source for rabbits) means rabbits must compete for the remaining limited food.

Answer:

D. The amount of vegetation decreases due to a drought in a rabbit habitat.
