Question

The major cause of environmental degradation is ____

(a) Bio-magnification

(b) Nitrogen deposition

(c) Quorum quenching

(d) Lyophilization

I got this question in an interview for job.

I would like to ask this question from Issues for Environmental Biotechnology topic in section Issues and Scope of Environmental Biotechnology of Environmental Biotechnology

Answer 1

The correct option is (b) Nitrogen deposition

To explain: Nitrogen deposition is the major cause of environmental degradation as increased nitogen in the soil and water leads to loss of species and shifts occur in plant communities, whereas, Bio-magnification is the process by which toxic substances get deposited in the food chain, quorum quenching leads to inhibition of quorum sensing and lyophilization is a process of freeze drying.
