Explanation / Answer
answers:
80) d (red tide)
81) d ( energy)
Explaination : The loss of energy at each tropic level places a limit on how many top level carnivores a community can support.
82) b ( a language)
83) d (Secondary Carnivores)
Explaination: Toxin move up the food chain, so that predator ingest higher concentration.
84) C (genetic drift)
85) A ( it mimics the female hormone estrogen)
86) C ( Biological magnification )
Explanation: Biological magnification is an increase in the concentration of chemical as it passed upward towards in a food chain.
