Earthworm is a 

biology interdependence in living beings - plants and animals animals as consumers scavengers and decomposers interdependence between plants and animals

  1. Herbivore

  2. Secondary consumer

  3. Tertiary consumer

  4. Detrivore

Show answer
Correct Option: D
Explanation:

Decomposer is an organism which decomposes dead organic matter. They breakdown organic matter of dead animals and plants and release nutrients in the environment. Detritivores are also called as detritus eaters. They are heterotrophs that obtain nutrients by consuming detritus (decomposing plant and animal matter). Earthworm is an example of detrivore.

Thus, the correct answer is 'Detrivore.'

The last chain of food is

  1. producers

  2. decomposers

  3. parasites

  4. none of the above

Show answer
Correct Option: B
Explanation:
A. Producers are photosynthetic green plants. They are autotrophs as they convert solar radiations into chemical energy and prepare their own food.
B. Decomposers are micro consumers that reduce organic remains. They form the last step of the food chain because they breakdown detritus (the dead remains of plants and animals) into smaller particles.
C. Parasites are the organisms that live in or on the host organism from which they derive their nutrition.
So, the correct answer is 'Decomposers'.

The decomposers in an ecosystem

  1. convert inorganic material, to simpler forms

  2. convert organic material to inorganic forms

  3. convert inorganic materials into organic compounds

  4. do not break-down organic compounds

Show answer
Correct Option: B
Explanation:
Decomposers are micro consumers and include certain bacteria and fungi. They are known as saprophytes and release the minerals trapped in organic remains of plants and animals. The process of decomposition occurs outside the body of decomposers. They release enzymes on the organic dead remains which decompose them into simple inorganic substances which are absorbed by decomposers.
So, the correct answer is 'convert organic material to inorganic forms'.

Which of the following microorganisms convert nitrogenous waste into nitrogen compound?

  1. Bacteria and Fungi

  2. Fungi and Protozoan

  3. Protozoan and Algae

  4. Protozoan and Bacteria

Show answer
Correct Option: A
Explanation:

Bacteria and fungi belongs to the class of decomposers. They act on the waste materials and converts the nitrogen present in the waste to useful nitrogenous compounds. It also increases the nitrogen content of the soil and increases the fertility of the soil.

So, the correct answer is option A.

......... are also called saprophytes.

  1. Producers

  2. Consumers

  3. Decomposers

  4. Parasites

Correct Option: C

Which of the following is nature's cleaner?

biology interdependence in living beings - plants and animals animals as consumers scavengers and decomposers interdependence between plants and animals

  1. Consumers

  2. Producers

  3. Decomposers and scavengers

  4. Symbionts

Show answer
Correct Option: C
Explanation:
A food chain is series of plants/animals which are interrelated in the form of organism being eaten as food by the other. It consists of producers, consumers and decomposers. Plants are producers. The herbivores are primary consumers and carnivores are secondary consumers. Decomposers and scavengers are those which decomposes the waster organic matter and release energy back in the environment. Hence, they are also called as nature's cleaner. They are present in the apex of the pyramid.
Thus, the correct answer is 'Decomposers and scavengers.'

Bacteria and fungi are

  1. Scavengers

  2. Primary consumers

  3. Secondary consumers

  4. Decomposers

Show answer
Correct Option: D
Explanation:

Decomposers are microorganisms which decomposes organic matter. These include bacteria and fungi. They breakdown organic compounds obtained from the dead animals and leaves and releases carbon and energy back in the environment. They usually occupy the apex of the pyramid.

Thus, the correct answer is 'Decomposers.'

A detritivore is a/an

biology interdependence in living beings - plants and animals animals as consumers scavengers and decomposers interdependence between plants and animals

  1. Animal feeding on plant matter

  2. Animal feeding on decaying organic matter

  3. Plant feeding on an animal

  4. Animal feeding on another animal

Show answer
Correct Option: B
Explanation:

A detritivore is an animal feeding on decaying organic matter. It is a heterotroph that obtains nutrients by consuming detritus. Examples include millipedes, earthworms, fiddler crabs, sea cucumbers. 

Thus, the correct answer is 'Animal feeding on decaying organic matter.'

True or False:
Decomposers help in recycling matter.

Correct Option: A

The organisms, which attack dead animals are

biology interdependence in living beings - plants and animals animals as consumers scavengers and decomposers interdependence between plants and animals

  1. First link of the food chain are known as primary producers

  2. Second link of the food chain are known as herbivores

  3. Third link of the food chain are known as tertiary consumers

  4. Present at the end of food chain are detritivores

Show answer
Correct Option: D
Explanation:

The organisms which attack dead animals and obtain nutrition from their detritus (decomposing parts of plant and animals, even feces) are called as detritivores (kind of heterotrophs). They are present at the end of the food chain because they consume the highest trophic level organisms by their biomacromolecular digesting enzymes. Therefore, concluding the food chains often.

So, the correct answer to the question is 'Present at the end of the food chain are detrivores'.
