How do sulfur and phosphorus move from the biotic to the abiotic pools during their cycles? A) Primary consumers eat producers.
worty [1.4K]

Answer:D) Decomposers break down the remains of producers and consumers

Explanation:A biotic pool is a tidal pool with diverse and changing habitats of living factors. We can say they are important mini ecosystems within the larger ecosystem.

The abiotic pool involves the elemental phases of nature,the non living parts of the ecosystem. Decomposition (break down) of elements/organic compounds is the characteristic bridge between both pools into what is known as nutrients.

This tell us that the ultimate dead part of producers and consumers are used up in this process.

Some of the nutrients released in the biogeochemical cyclic process includes sulfur and phosphorus and they move through the ecosystem.

Note: The biogeochemical cycle is a pathway of movement for chemical elements.

The chemical elements in nature moves through both biotic and abiotic components via abiotic and biotic interaction in the ecosystem

Few abiotic factors includes rocks, air, water, and chemicals while biotic factors includes living organisms activities.

All living and non living elements of nature play vital roles in the great biogeochemical cycle.
