Question

Assertion:
Herbivores are also called key industry animals because they convert plant matter into animal matter.
Reason:
Decomposers play a pivotal role in the ecosystem and they indirectly support the producers.
A) Both assertion and reason are correct and the reason is the correct explanation for assertion
B) Both assertion and reason are correct but the reason is not the correct explanation for assertion
C) Assertion is correct but the reason is incorrect
D) Both assertion and reason are incorrect.

Answer 1

Hint: The ecosystem is the ecological structure and functional unit in which living organisms communicate with each other and with the surrounding environment and reside in harmony and collaboration. An ecosystem's structure can be split into two key components, namely: Biotic and Abiotic.

Complete answer:
Because of the capacity of a herbivore to live exclusively on hard and fibrous plant matter, the primary An animal that gets its nutrition from eating plants, and only plants, is a herbivore. Examples include herbivores and invertebrates such as crickets and caterpillars, as well as vertebrates such as deer, koalas, and many species of birds. For these animals, the digestive systems capable of handling significant amounts of plant material have evolved.
Herbivorous animals are key industry animals, according to Elton (1939), as they turn plant matter into the animal matter and the lives of all other consumers (higher animals) are dependent on these primary consumers.
A decomposer is an organism that decomposes or breaks down, organic material like the remains of dead animals. Bacteria and fungus comprise decomposers.
Decomposition is an essential process because it facilitates the regeneration of organic matter in an ecosystem. Decomposers in any ecosystem play an important role. Without decomposers, dead animals can not be broken down and recycled into other living matter.
By breaking down dead organisms and animal waste, decomposers get nutrients and energy. Decomposers release nutrients, such as carbon and nitrogen, back into the atmosphere through this process. Such nutrients are recycled back into the environment so that they can be used by producers. When they are ingested or consumed, they are transmitted to other species. Many of these nutrients are recycled back into the soil, so the roots of plants can pick them up.
In this way, producers are indirectly supported by decomposers and play a key role in ecosystems.
Thus from the above discussion, it is clear that both assertion and reason are correct but the reason is not the correct explanation of assertion thus option B is the correct answer.

Note: Animals who eat other animals are carnivores. The term carnivore comes from Latin and simply means "meat-eater."Wild animals, such as lions and tigers, such as snakes and sharks, are examples of vertebrate carnivores, whereas invertebrate carnivores include sea stars, spiders, and ladybugs, while invertebrate carnivores include sea stars, spiders, and ladybugs.
 Omnivores are animals that eat both foods derived from plants and animals. Omnivore in Latin means to eat anything. Examples of vertebrate omnivores are humans, bears, and chickens; cockroaches and crayfish are invertebrate omnivores.
