Question

toxins and contaminants can move up the food web and organisms at higher trophic levels can be threatened, even if the pollutant is introduced to the environment in very small quantities through a process known as ___________.

○ bioaccumulation
○ redistribution
○ pollutant compounding
○ trophic accumulation
○ bottom - up control

Explanation:

Bioaccumulation is the process by which toxins and contaminants build - up in organisms over time. As organisms at lower trophic levels consume pollutants, these pollutants are passed up the food web, threatening higher - trophic level organisms even with small initial pollutant quantities.

Answer:

A. Bioaccumulation
