|
|
|
Energy flows into living organisms and remains there, while chemical compounds are transferred from organism to organism.
|
|
|
Chemical compounds flow in one direction in a food chain and energy is produced.
|
|
|
Energy is transferred from organism to organism in a food chain and chemical compounds are recycled.
|
|
|
Energy flows out of living organisms and is lost, while chemical compounds remain permanently inside organisms.

Detailed explanation-1: -So, the correct answer is ‘Energy flows while matter is cycled’. Was this answer helpful?
Detailed explanation-2: -So, the correct answer is ‘Energy flows while matter is cycled’.
Detailed explanation-3: -The correct answer is 3. A food web shows how energy is transferred in an ecosystem. For instance, the solar energy is transferred to the producers such as plants so that they can convert it into chemical energy. The chemical energy stored in producers are transferred to the consumers once they eat the plants.
Detailed explanation-4: -There is a flow of energy from one trophic level to the other in a food chain. Producers bring energy from the sun into the community. Primary consumers eat the producers, which makes them herbivores in most communities. Secondary consumers eat the primary consumers, which makes them carnivores.
Detailed explanation-5: -All these nutrients are released back into the abiotic world when the organisms die and decompose, which once again enters the biotic world through the producers. Therefore matter flows cyclically in an ecosystem. Energy flow however, is always uni-directional, i.e from sun to producers to consumers.
