Biomagnification: Osprey A bird rehabilitation center is hoping to breed its ospreys. Knowing the dangers of biomagnification to the birds' eggs and young, what strategies might they take to minimize the danger? (Choose all that apply.) Check All That Apply Feed the ospreys smaller fish Feed the ospreys larger fish, but fewer of them. Feed the ospreys fish from a toxin-free ecosystem
Feed the ospreys smaller fish. Feed the ospreys larger fish, but fewer of them. Feed the ospreys fish from a toxin-free ecosystem. Encourage the ospreys to drink large amounts of clean water. No strategy can help, since biomagnification is an inherent property of each species. Feed the ospreys only carnivorous fish.
Biomagnification: Which species to test? A researcher is concerned about a chemical in the Lake Kariba ecosystem that has the potential to biomagnify, much like DDT. Due to limited resources, pollutant levels can be tested in only two species. Which two species are the best to compare to reveal possible biomagnification between them? (Choose two.)
