What does not cycle through an ecosystem?
Thus, the correct answer is ‘Energy.’
Which of the following plastics Cannot be used to make petrol?

Which of these is continuously recycled in ecosystem?
Explanation: The mineral nutrients that recycle in nature are carbon, sulfur, nitrogen, phosphorus, oxygen, among others etc. These continually recycle along with other mineral nutrients into productive ecosystem.
How is matter recycled?
Unlike energy, matter is recycled in ecosystems. Decomposers release nutrients when they break down dead organisms. … nutrients pass to primary consumers when they eat the plants. When living things die, the cycle repeats.
Is phosphorus recycled in an ecosystem?
Of all the elements recycled in the biosphere, phosphorus is the scarcest and therefore the one most limiting in any given ecological system. … Some of it passes through freshwater and terrestrial ecosystems via plants, grazers, predators, and parasites, to be returned to those ecosystems by death and decay.
How are nutrients recycled on Earth?
Nutrients in the soil are taken up by plants, which are consumed by humans or animals, and excreted again by them — or they are released back into the environment when organisms die (e.g. plants lose their leaves). … Essentially, all nutrients that plants and also human beings require to survive are cycled in this way.
