2. mercury has contaminated the water source that the fish below live in. as this fish grows older, the concentration of mercury in this fish has increased. this is an example of...
3. in habitat fragmentation, who might benefit?

Explanation:

1. Habitat destruction is a major cause of biodiversity loss as it removes the living spaces of species.
2. Biomagnification is the process where the concentration of a pollutant (like DDT) increases as it moves up the food chain.
3. Bioaccumulation refers to the increase in concentration of a substance (mercury) in an organism over time.
4. In habitat fragmentation, species that thrive in edge habitats (which increase in fragmented landscapes) might benefit.

Answer:

1. B. Habitat destruction
2. D. Biomagnification
3. A. Bioaccumulation
4. B. Species living in the edge habitat
