Question

An association of individuals of different species living in the same habitat and having functional interaction is
A. Population
B. Ecological niche
C. Biotic community
D. Ecosystem

Answer 1

Hint: There are various interactions between animals and plants in nature. They help each other to co-exist either by benefiting or harming each other. This relationship is very specific. It sometimes makes them sensitive to some growths making them indicators for the same. These interactions make the environment.

Complete answer:Ecosystem is the whole of the species of every kind on our planet Earth. There are units that make this large biome possible. The change in the basic unit will affect all the rankings in the hierarchy thereby, affecting the largest ranking. Ecology is the sum of all the different varieties in our surroundings. The manner in which organisms reside therefore becomes very important to understand. Ecological hierarchy means the ranking of the ecological members. Every species existing in the universe makes the ecology. So the hierarchy places them in order- individual, population, community, ecosystem, biome, biosphere. The ecosystem is made up of many communities spread in larger areas. They all have different characteristics but live in the same atmosphere under the common universe. Community is the gathering of different populations. Different species populations make the community of an area. The community prevails in various types of interactions between two organisms, this can be beneficial or harmful.
Option A: Population: They may live in the same habitat but can have different functional interactions. It varies from place to pace.
Option B: Ecological niche: This shows the position of a species in the ecosystem. It also tells about its role in the ecosystem.
Option C: Biotic community: All the living species when living in the same habitat and have the same functional interactions, they make the biotic community like plants, animals, etc.
Option D: Ecosystem: the biotic and abiotic components together make the ecosystem.
So the answer is an option: Biotic community

Note: Abiotic components refer to the non-living things in the ecosystem. For example – rock, water, light, etc. will shape the ecosystem and enhance the beauty of nature. The interactions between both biotic and abiotic components will give the whole organized ecosystem.
