Question

which of the following describes an example of competition between species? a a tick lives on a deer. b a fungus and an alga live together as a single organism. c two species of bird feed on the same berry tree. d a snake hunts a rabbit.

Explanation:

• Option A: A tick living on a deer is an example of parasitism, where one organism (the tick) benefits at the expense of another (the deer).
• Option B: A fungus and an alga living together as a single organism (like in lichens) is an example of mutualism, where both organisms benefit from the relationship.
• Option C: Two species of bird feeding on the same berry tree is competition. Competition occurs when two or more species vie for the same limited resource (in this case, the berries on the tree).
• Option D: A snake hunting a rabbit is an example of predation, where one organism (the snake - the predator) hunts and consumes another (the rabbit - the prey).

Answer:

C. Two species of bird feed on the same berry tree.
