Why is the nitrogen cycle important for the survival of organisms in an ecosystem? A. The nitrogen cycle recycles nitrogen throu
gh an ecosystem, making it available to all organisms. B. The nitrogen cycle keeps organisms from consuming nitrogen in their ecosystem. C. The nitrogen cycle allows all organisms in an ecosystem to consume nitrogen instead of consuming each other. D. The nitrogen cycle stores nitrogen in safe places, keeping it from entering an ecosystem.
A. The nitrogen cycle recycles nitrogen through an ecosystem, making it available to all organisms.
Explanation:
Nitrogen is a vital nutrient in ecosystems. The point of the nitrogen cycle is to recycle it so that it keeps being put back into an ecosystem.
For instance, animals need nitrogen in their diets. They get nitrogen by eating plants which obtain nitrogen from the soil. But how does nitrogen get into the soil? Well, decomposers can decompose dead organisms and recycle their nitrogen so that it enters the soil again. If there wasn't a nitrogen cycle, all the nitrogen would eventually be used up and ecosystems would suffer.
Nitrogen is an essential nutrient for plants and a significant component of proteins, which all animals need to grow, reproduce and survive. The nitrogen cycle converts nitrogen into compounds that plants and animals can use.
