Question

in which trophic level chemicals like ddt are accumulated in highest concentration? why?

Answer 1

Chemical like ddt are accumulated higher in concentration in the tertiary consumers ans the level of chemical gets increased due to biomagnification!

Answer 2

Answer:

Chemicals like DDT are accumulated in tertiary consumers.

Explanation:

• Biomagnification is the accumulation of a chemical by an organism as a result of exposure to both food and water, resulting in a concentration that is higher than what would have been expected from equilibrium and higher than what would have occurred with only water exposure.
• The biomagnification mechanism causes the concentration of DDT in an animal's body to increase the higher up the food chain the animal is (for example, tertiary consumers like seals).
• The highest trophic level is formed by tertiary consumers.
• Higher up the food chain, or as we move up the trophic levels, the number of harmful non-biodegradable compounds that collect within an organism's body increases.
• Biomagnification is the term for the sharp rise in DDT levels in tertiary consumers compared to Primary consumers.
