Q10. You are studying the effect of a new pollutant on an ecological community in a lake that has three mysterious species. You sample the concentration of the pollutant in each species for 4 years after the pollutant first appeared. The graph below displays your data.
Which option below most likely describes the nature of the pollutant and the trophic levels of each of the three mysterious species?
The pollutant is bioaccumulating in the community. Species B is a producer, Species A is a primary consumer, and Species C is a predator.
The pollutant is bioaccumulating in the community. Species C is a producer, Species B is a primary consumer, and Species A is a predator.
The pollutant is causing eutrophication of the lake. Species A is a producer, Species B is a primary consumer, and Species C is a predator.
The pollutant is neither bioaccumulating in the community nor causing eutrophication. Species C is a producer, Species B is a primary consumer, and Species A is a predator.

2) Species - A is a predator as o comes on the top of trophic level hence when they kill the primary consumer all the substance are kepp on accumulating in the body hence more bio accumulation..!!
3) Species - B is a primary consumer as when they die the substance are released in the marine environment thus resulting in a release of the substance in the water causing eutrophication..!!
4) Species - C is a producer as it is the first level in the topic level hence the accumulating of the substance is also low and hence I also causes less eutrophication on dying..!!
