What does animal waste decay create?
Hereof, how do organisms use nitrogen quizlet?
Once bacteria in the roots of plants have "fixed" the nitrogen, the nitrogen can be used by organisms to build proteins and other complex substances. Plants absorb the nitrogen. Animals eat the plants. Decomposers break down these complex compounds in animal waste and in the bodies of dead organisms.
Regarding this, what are the elements important to life that are recycled?
Valuable elements such as carbon, oxygen, hydrogen, phosphorus, and nitrogen are essential to life and must be recycled in order for organisms to exist. Nutrient cycles are inclusive of both living and nonliving components and involve biological, geological, and chemical processes.
Plant and animal wastes decompose, adding nitrogen to the soil. Bacteria in the soil convert those forms of nitrogen into forms plants can use. Plants use the nitrogen in the soil to grow. People and animals eat the plants; then animal and plant residues return nitrogen to the soil again, completing the cycle.
