This is biological magnification; the concentration of poison in the environment gets higher and higher as it goes up the food chain. The poisons are kept in the bodies of the animals that eat them. They are not broken down or eliminated. So a predator that is higher up the chain gets a lot of the poison from its food.

∙ 14y agoIf you assume that 1 gram of a harmful chemical went on each plant in an area and assume that a rabbit eats 10 plants then the rabbit has consumed 10 grams of the harmful chemical. If a fox then eats 10 rabbits it has then consumed 100 grams of the harmful chemical and this dosage is likely to be more harmful then the small doses which the rabbits consumed, particularly if it has a cumulative effect and remains in the body. So if the fox ate 10 rabbits a day it might have 3000 grams of the chemical in its system after a month.

∙ 13y agoMany insects are killed by poisons. Many others are simply made weak. The weak insects are easy for their predators to catch. As their predators catch insects full of toxins, the toxins build up in their blood. Their predators could be a spider less affected by the toxin. As their predators catch the weakened insects, they become sick, it becomes easier for their predators to catch them. The predator could be a small bird. As the toxin builds up in it, it acts sicker and easier to catch. This keeps happening until a hawk or eagle ends the build up. Each time, the smaller animal is eaten, the smaller animal is digested. it is turned into energy and building blocks for the larger animal. The poison is not digested but is simply stored in the tissues of the larger animal.
For that reason humans are not fit for human consumption.

How would you explain the need for biodiversity?
A constant environment will not select different animals but if we assume that the earth's environment is changing then a wide range of genetic variation and a wide range of biodiversity will mean that as the environment does change then at least some of the organisms will survive
What is the environment for a zoologist?
around animals
Environment and its components?
The environment is defined as the surroundings of man and other living things. It comprises of four major components namely: Hydrosphere (Water bodies), Atmosphere (air), Lithosphere (earth's crust) and Biosphere (living things).

I can't particularly tell what you are asking because of the grammar, but here it is calledcamouflage.
Explain why it is important for plants and animals to be adapted to their environment?
their would be to many bugs they would destroy important life cycles
Explain how energy is transferred into the environment?
Energy is transferred into the environment by the sun. The sun provides the base energy for all ecosystems in the world. Plants turn sunlight into chemical energy through photosynthesis. Then, animals eat the plants for energy, and other animals eat those animals and other animals eat THOSE animals and so forth. Another way to look at it is to say that energy is transferred into the environment whenever you burn fossil fuels.

How does looking after the environment important for animals?
Looking after the environment is important for animals as the environment is their habitat - where they live. If we don't look after the environment then the animals will lose their habitats - for instance, cutting down loads of trees is bad for animals as well as the environment because you are getting rid of loads of different creatures' habitats.
