Tell me a few of the food chains around us

i) Cotton - cotton aphid - aphid-eating fly - ladybug - sparrow - eagle ii) grass - grasshopper - frog - snake - owl.

3) Grass – Rat – Snake – Eagle.

iv) Grass – Grasshopper – Spider – Chickadee – Eagle.

Grass - aphids - small birds - snakes - eagles.

Rice Keichi - vole - owl.

Grass - sheep - wolf.

Rice - locusts - frogs - pants poor old snake - eagle.

Cotton - cotton aphid - aphid fly - ladybug - sparrow - husheng - eagle grass - grasshopper - frog - snake - owl.

Grass - Rat - Snake - Eagle.

Grass – grasshopper – spider – – eagle.

Examples:

1. Grass, hare, snake, eagle.

2. Cereals, insects, frogs, snakes.

3. Big fish, small fish, dried shrimp, zooplankton, green algae.

Food Chain and Ecological Balance:

It is generally believed that the more complex the food web, the stronger the ability of the ecosystem to resist external interference, and the simpler the food web, the more prone the ecosystem is to fluctuations and destruction.

Suppose there is only grass, deer and wolves living on an island. In this case, as soon as the deer disappears, the wolf starves to death. If there are other herbivores besides the deer (such as cattle or antelopes), the effect on the wolves will not be as great once the deer disappears.

On the other hand, if the wolf is wiped out first, the number of deer will increase dramatically due to the loss of control of the deer, and the grass will be over-eaten, and as a result, the number of deer and grass will drop greatly, or even fall to the hands of the gods.

If there is another carnivore other than the wolf, once the wolf is extinct, the carnivore will increase the predatory pressure on the deer without causing the deer to spread too much, thus potentially preventing the collapse of the ecosystem.

Big fish eat small fish, small fish eat dried shrimp, and dried shrimp eat mud.

There are several food chains in the picture, because there is no picture, give you an example.

There are five food chains in the picture.

Grass - rabbit - fox.

Similar to the collapse of the beam, you can also find out the food chain in your diagram.

If you don't understand, you can ask.

1. Little grass, rat, fox.

2. Grass, rabbit, fox.

3. Grass, rats, and eagles.

4. Grass, rabbits, and eagles.

5. Small grasses, locusts, frogs.

6. Grass, rabbit, snake.

7. Grass, rabbits, owls.

8. Grass, rats, snakes.

9. Grass, mice, owls.

10. Small grasses, locusts, and birds.

Dear, I'm glad to answer for you: What are some examples of the food chain? Answer: Food chain example:

1. Predatory food chain: based on plants, the latter preys on the former. Such as grass - hare - fox - wolf.

2. Broken food chain: refers to the food chain formed on the basis of broken food. Such as leaf fragments and small algae, a shrimp (crab) - fish - fish-eating birds.

3. Parasitic food chain: based on large animals, the food chain formed by small animals parasitizing large animals. Such as mammals-fleas-protozoa-protozoa-bacteria-filtered viruses.
