The question asks to identify the correct statement about decomposers. To answer this, we need to recall the fundamental role of decomposers in an ecosystem and how they obtain energy and process matter.
Correct Option: B) They convert organic matter into inorganic substances
This question tests knowledge of ecological roles within an ecosystem, specifically focusing on how organisms obtain energy. We need to classify earthworms, dung beetles, and millipedes based on their feeding habits.
Correct Option: B) Detritivores
The question asks about the consequences of removing decomposers from an ecosystem. To answer this, we need to understand the role of decomposers in nutrient cycling and energy flow within an ecosystem.
B) Run out of available nutrients for producers. Decomposers are crucial for recycling nutrients from dead organic matter back into the ecosystem, making them available for producers. Without decomposers, these essential nutrients would remain locked in dead biomass, leading to a depletion of available nutrients for new growth.
The question asks to identify which of the given options is NOT a function of decomposers. We need to recall the primary roles of decomposers in an ecosystem and then evaluate each option against these roles.
Based on this analysis, the production of organic compounds from inorganic ones is not a function of decomposers.
Correct Option: B) Producing organic compounds from inorganic ones
The question asks to identify the biotic components of an ecosystem. An ecosystem consists of both biotic (living) and abiotic (non-living) components. Understanding the distinction between these two categories is key to answering this question.
Correct Option: C) Producers, consumers and decomposers are the living components of an ecosystem. They represent the biological aspects and interactions within the ecosystem.
The question asks to identify an abiotic component of an ecosystem. An ecosystem consists of two main types of components: biotic (living) and abiotic (non-living). Understanding this fundamental classification is key to answering the question.
C) Temperature is a non-living physical factor that significantly affects the life processes and distribution of organisms within an ecosystem. Therefore, it is an abiotic component.
