Question

Which one of the following levels of ecology most considers the effects of predation and interspecific competition on the distribution and abundance of organisms

• A. Biotic
• B. Community
• C. Ecosystem
• D. Population

Answer 1

The correct option is B Community

• A community is a group or association of populations of two or more different species occupying the same geographical area and in a particular time, also known as a biocoenosis. Predation is one of the factors believed to have a major impact on competitive interactions. Intraspecific competition is an interaction in population ecology, whereby members of the same species compete for limited resources. Effect of predators on competition between their prey have resulted in almost every conceivable outcome i.e, increase or decrease its impact on the community. SInce community consists of different types of organisms, the effects of predation and interspecific competition would be maximum in this level of ecology.

So the correct option is 'community'.
