Answer: C) density-dependent inhibition
Explanation: When density is high. cell division is inhibited. Density-dependent inhibition occurs when cells grow to a limit and the density of the area is high, growth becomes inhibited as a result of competition for nutrients, space and growth factors. When such arises, the cells get a notification to stop division.
The biogeochemical cycles refer to the pathway through which chemical substances move through the abiotic and biotic sections of the earth. The chemical substances that are usually moved through these cycles include: carbon, water, nitrogen, phosphorus, sulfur, etc.
The purpose of biogeochemical cycles is to transfer the necessary nutrients from the environment into the living organism and then back into the environment again, thus, the cycle functions by recycling the chemical substances that are part of living organism.
