Which of the following is an example of how biogeochemical cycles are important to sustaining life?
A
The atoms in water molecules are destroyed during a drought.
B
Oxygen atoms are converted into carbon atoms during respiration.
C
New carbon atoms are created during the carbon cycle.
D
Nitrogen waste from an organism is converted into usable nutrients for others.
Explanation: 

Detailed explanation-1: -Expert-Verified Answer. The statement ‘nitrogen waste from an organism is converted into usable nutrients for others’ is an example of how biogeochemical cycles (Option d). The biogeochemical cycles refer to how different element circulates between non-living things (abiotic) and living things (biotic) in an ecosystem.

Detailed explanation-2: -Which biogeochemical cycles are key to life? Water, which contains hydrogen and oxygen, is essential for living organisms. That places the water cycle pretty high on the list of cycles we care about!

Detailed explanation-3: -Biogeochemical cycles help in the regulation of natural elements that are necessary for living beings, by channeling through physical and biological phenomena. It acts as a recycling procedure in nature.

Detailed explanation-4: -Some examples of the biogeochemical cycles are the phosphorus cycle, oxygen cycle, carbon cycle and nitrogen cycle. Human activities have different impacts on the various biogeochemical cycles.

Detailed explanation-5: -Carbon Cycle Carbon is one of the most important elements to living organisms, as shown by its abundance and presence in all organic molecules. The carbon cycle exemplifies the connection between organisms in various ecosystems.
