Question

Which of the following statements about adaptive radiation is correct? a. Adaptive radiation occurs very slowly over time. b. Adaptive radiation occurs within a single lineage. c. Adaptive radiation occurs in the presence of competitors. d. Adaptive radiation occurs in species that live in one habitat.

Answer 1

Answer:

c. Adaptive radiation occurs in the presence of competitors.

Explanation:

Adaptive radiation is a process of diversification in which  new species are originated from an ancestral species due to changes in the enviroment or deu to pressures such as competition for resources that lead organisms to find new niches. For example, if there are many competitors for the same food source, that pressure could lead some organisms to look for a new food source, that, in turn, can lead to the adaptation of their body to the new food source. For example, bird beaks that were specialized for seeds can be adapted for insects.
