C Correct answer
Explanation

Both native animals and transgenic animals suffer in different ways - native animals from ecological disruption and competition, and transgenic animals from the genetic manipulation procedures and health effects. The question asks which suffers more, and the answer implies both experience significant suffering.

  1. Bioremediation

  2. Biomagnification

  3. Eutrophication

  4. Bioaccumulation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Bioremediation is the use of living micro organisms to degrade the environmental contaminants into less toxic forms. It uses naturally occurring bacteria and fungi or plants to degrade or detoxify substances hazardous to human health and the environment.
