Question

In spite of interspecific competition in nature, which mechanism the competing species might have evolved for their survival?

• A. Competitive release
• B. Resource partitioning
• C. Mutualism
• D. Predation

Answer 1

The correct option is B

Resource partitioning

The correct option is B.

Explanation for the correct option:

1. The coexistence of species in the same habitat is aided by resource partitioning.
2. This explains how comparable species survive competition in an ecological niche without causing the extinction of weaker species, allowing an ecosystem to maintain a high level of biodiversity.
3. Resource partitioning, which helps prevent rivalry in an ecological niche, is the division of scarce resources among species.
4. Because creatures struggle for scarce resources in every environment, diverse species must learn to live in harmony.

Explanation for incorrect options:

Option A:

1. When environmental conditions change, competition can diminish population abundance and increase the chance of extinction, but if competition and environmental change cause selection pressure to parallel, adaptation can be accelerated.

Option C:

1. Mutualism is a sort of interaction in which neither the host nor the symbiont suffers any negative effects.
2. The duration of this partnership could be either longer or shorter.
3. The word "mutualist" denotes that the host and the tiny partner are the other participants involved in the mutualism.

Option D:

1. The number of individuals in the prey population is reduced as a result of predatory behavior.
2. Carnivorous interactions, in which one species eats another, are the most well-known forms of predation.

Final answer: In spite of interspecific competition in nature, the competing species might have evolved resource partitioning for their survival
