Question

Which of the following is an important part of the natural release of biogas in the environment?

(a) Biogeochemcial cycle

(b) Environment pollution

(c) Afforestation

(d) Deforestation

I have been asked this question in an international level competition.

My doubt stems from Enzymes Catalyzing Pesticide Degradation Reactions topic in section Biodegradation of Pesticides in the Environment of Environmental Biotechnology

Answer 1

Correct option is (a) Biogeochemcial cycle

The best I can explain: The natural release of biogas in the environment due to the activity of methanogens leads is crucial for biogeochemical cycle, whereas, biogas does not lead to a considerable amount of environment pollution, afforestation and deforestation are caused by human intervention.
