How are pesticides passed through the food chain?

Answer 1

There are a couple of main routes: * A bug would absorb the pesticide, and be eaten (before or shortly after death) by a bird or other insectivore. That animal would then absorb whatever of the pesticide the bug hadn't metabolised or ejected. From there, it would be passed on through the food chain as normal, the amount of poison transferred lowering bit by bit - assuming that no animals in the chain ate any more infected bugs or plants, as below. * A plant may absorb the chemicals from the ground or air, following its release. The plants may be eaten by bugs and insects and follow the above course, or they may be eaten by herbivores like cattle and sheep. There on, same as usual; some gets broken up, some gets tossed out, but some carries on to whatever eats the herbivore, and some again to whatever eats that predator. Either way, the pesticide is passed on like every other chemical in a food chain; part is used by the animal at each stage, part is excreted as waste (possibly to rejoin the cycle later) and part is then consumed by the next stage. And so on ad nauseam or until all of the poison is destroyed or altered.

Answer 2

Many foods are treated, but washed many times before it even reaches the consumer who many times will wash it anyway. It should not actually be inside the food since not enough is applied normally to penetrate the soil & there are safeguards if it does. Moisture dilutes out almost anything & would have to be much stronger than legal limit to be harmful when soil moisture comes into play.

Answer 3

Pesticides kill what we determine to be pests - but that pest is the prey of other animals. Chemicals are often waterborne to lie dormant, awaiting absorption by other animals. This was the case with DDT in America, almost leading to the loss of the Bald Eagle (and many other forms of life).

Answer 5

Humans put pesticide on the plants. Insects then eat the plant and become sick, but may not die right away. They may scuttle, fly, crawl, or however they move away, only to get eaten by something else, which gets eaten by something else, so on and so forth. OR, a herbivorous creature may eat your plant and then that gets eaten, etc. etc.

Answer 6

Pesticides affect the food chain because even the smallest bacteria or producer can absorb the pesticides and as you continue up to the food chain to the consumer or herbivore (veggie eater) or carnivore (meat eater), they have absorbed many amounts of pesticides because they have eaten other producers that have absorbed the pesticides.

Pesticides are toxic chemicals that can cause mutations along with birth defects and can even cause cancer. They can also poison an entire ecosystem.

Answer 7

Consequences of pesticides entering the food chain are the extinction or endangering of animals and the spread of harmful diseases to other animals and humans.
