A toxic material that has the potential to accumulate in the fat tissue of animals is accidentally released into an ecosystem. Plants and animals in this system include red-tailed hawks, mice, corn, and weasels. Arrange the organisms in order according to the level of toxins that they would be expected to accumulate
What will be an ideal response?
Higher concentrations of the toxin would be found as one "goes up" the food chain. Therefore corn should have the lowest, then mice, weasels and red - tailed hawks the greatest concentration.
