Challenge Question #19
"Do you think a small, medium or large fish would potentially contain more
toxins? Explain why."
The largest fish will have more toxins because it ate more fish which ate
more green algae which absorbed the toxins from the water. The small fish
ate 1000 grams of green algae, and 100 grams of water flea and 10 grams of
Dragonfly nymph. The medium fish ate 10,000 grams of green algae, and 1000
grams of water flea and 100 grams of Dragonfly nymph and 10 grams of little
fish. The large fish ate 100,000 grams of green algae and 10,000 grams of
water flea and 1,000 grams of Dragonfly nymph and 100 grams of little fish
and 10 grams of medium fish. Everything in the water can absorb the toxins
and the large fish are eating a lot more things that have toxins in them.
