Which situation would not encourage competition? select one: a. the amount of vegetation decreases due to a drought in a rabbit habitat. b. a long, wet season results in additional earthworms in a robin habitat. c. a long dry season results in a decrease in pond algae in a fish habitat. d. a wet, rainy season results in flooded caverns foxes normally use as shelters.

Competition is defined as rivalry, in which organisms compete or interact to gain a share of an environmental resource. The competition can be healthy or harmful.

The correct answer is:

Option B. A long, wet season results in the additional earthworms

Competition occurs between organisms in an ecosystem with a limited share of limited environmental resources.

The organisms when trying to gain or obtain the same resource, causes the overlapping of niches, eventually leading to competition. The animals primarily compete for food, water, and shelter.

The robin is a carnivorous bird, which feeds on worms and beetles. The increment in the population of the worms in robin habitat will decrease the competition. The robin will have a high amount of food, and thereby discouraging the competition.

Therefore, Option B is correct.
