Question

Which of the following statements about biogeochemical cycles is true? a. biogeochemical cycles are cycles involving only nonliving components. b. the rock cycle is a biogeochemical cycle. c. biogeochemical cycles are not an important part of the earth system. d. carbon, nitrogen, and oxygen cycles are biogeochemical cycles.

Answer 1

The correct statement about biogeochemical cycles is that carbon, nitrogen, and oxygen cycles are examples of these cycles, which involve recycling inorganic matter between living organisms and their nonliving environment.

Step-by-step explanation:

The correct statement about biogeochemical cycles is d. carbon, nitrogen, and oxygen cycles are biogeochemical cycles. Biogeochemical cycles are the recycling of inorganic matter between living organisms (the biotic components) and the abiotic, nonliving environment. These cycles involve a series of interconnected pathways that include both living and nonliving components. The carbon cycle, nitrogen cycle, and oxygen cycle are prominent examples of biogeochemical cycles that play a critical role in sustaining life on Earth by recycling essential elements. The rock cycle, contrary to one of the options given, is not categorized as a biogeochemical cycle because it does not directly involve the biological processes of living organisms.
