Most diverse organisms of an ecosystem are
1 producers
2 consumers
3 carnivores
4 decomposers
Explanation:
Decomposers include the most diverse group of organisms including bacteria fungi and other living organisms that breakdown the organic matter accumulated in the bodies of consumers into inorganic material. Producers- Producer are organisms the make their own food Exp.-green plant, small shrub. Consumers- Any organism that can't make its own food. Consumers have to feed on producer. Carnivores- carnivores are animal that eat other animal.

The highly degraded organic matter rich in nitrogen and potassium in particular, resulting from the activity of earthworms, is called
1 Worm castings
2 Vermicompost
3 Compost bedding
4 Humus
Explanation:
The highly degraded organic matter rich in nitrogen and potassium in particular, resulting from the activity of earthworms, is called vermicompost. Vermicomposts are rich in nutrition and thus, they are widely used as biofertilizers in organic farming and sewage treatment plants.

Increase in the concentration of a pollutant at successive trophic levels in an aquatic food chain is called
1 Biodegradation
2 Eutrophication
3 Bio-remediation
4 Bio-magnification
Explanation:
Increase in the concentration of a pollutant at successive trophic levels in an aquatic food chain is called Bio-magnification. Biomagnification is the accumulation of a chemical by an organism from water and food exposure that results in a concentration that is greater than would have resulted from water exposure only and thus greater than expected from equilibrium.
