Vertical distribution of different species occupying different levels in a biotic community is known as:
1 Stratification
2 Zonation
3 Pyramid
4 Divergence
Explanation:
Vertical distribution of different species occupying different levels in a biotic community is known as stratification. For example trees occupy top vertical strata or layer of a forest, shrubs the second and herbs and grasses occupy the bottom layers.

Which among the following is not a functional unit of the ecosystem?
1 Decomposition
2 Nutrient cycling
3 Energy flow
4 Pollution
Explanation:
Pollution is not a Functional unit of the ecosystem. The ecosystem is the Functional unit of the environment system i.e. ecology. The abiotic components provide the matrix for the synthesis of organic components.

The species, though insignificant in number, determine the existence of many other species in a given ecosystem. Such species is known as .
1 Sacred species
2 Endemic species
3 Keystone species
4 Extinct species
Explanation:
Keystone species hold together the complex web of relationship in an ecosystem. They can be animals, plants or microorganisms. Example of keystone species includes starfish, Sea otters, wolves elephants, tiger, lion etc.

Which of the following supports a dense population of plankton and littoral vegetation?
1 Oligotrophic
2 Eutrophic
3 Lithotrophic
4 Agroecotrophic
Explanation:
Eutrophication means nutrient enrichment. The main factor that cause eutrophication is the release of large amount of phosphate and nitrate into water body. The enrichment of minerals allow large number of algae, cyanobacteria \& aerobic bacteria to grow.
