2 Rabbits, mice, frogs, snakes, owls, wolves, do spiders eat herbivorous insects, do they eat insect

Herbivorous insects are: frogs, spiders.

The rest do not eat) The birds that eat insects are: snakes, owls, wolves, spiders (in the rainforest) (the rest do not eat).

In general, this is the case, which excludes deliberate human feeding.

First of all, there is a lack of producers in the conditions of the question, so the producers (HerbsI add it, too.

How can there be so many skilled here! I think there are only five or six at most, first of all, cats eat mice, mice eat grass, this is a food chain, foxes eat rabbits, rabbits also eat grass! You don't have eagles here, there should be eagles that eat snakes and snakes eat frogs, and frogs eat bugs, which is also a food chain.

The beginning of the food chain is usually the green plants (producers), from which there must be at least three trophic levels. Writing the food chain starts with the kind of organism (producer) that starts with the energy transfer in the ecosystem, rather than with the abiotic component, such as the sun. There are many creatures in the food chain, and the latter can feed on the former, such as in the grassland, grass, hare, fox, wolf;

The biological chain between them, let me tell you, ah, ah, owls eat mice, rabbits eat grass, frogs eat bugs, spiders. Snakes eat frogs. Fox eats insect birds.

Summary. Hello dear, foxes, rabbits, snakes, frogs, insectivorous birds, insects, mice, eagles, they constitute a predatory relationship between snakes eating rabbits and mice. Eagles, eat rabbits, snakes, frogs.

Eagles prey on rats, insectivorous birds, and snakes, insects, rabbits, and rats feed on plants, snakes feed on rabbits and rats, and insectivorous birds feed on insects. Food chain is an ecological term first proposed by British animal ecologist Elton in 1927.

Foxes, rabbits, snakes, frogs, insectivorous birds, insects, mice, eagles, which of them constitute a predatory relationship? (Let's say a fox eats a rabbit).

Hello kiss, foxes, rabbits, snakes, frogs, insectivorous birds, rolling insects, mice, eagles, they constitute a predatory relationship between snakes eating rabbits and mice. Eagles, rabbits, snakes, frogs. Eagles prey on rats, insectivorous birds, and snakes, insects, rabbits, and rats feed on plants, snakes feed on rabbits and rats, and insectivorous birds feed on insects.

Food chain is a term first proposed by the British animal ecologist Elton in 1927.

The food chain reveals the laws of matter circulation and energy flow in biological systems, pointing out that when matter and energy are transformed from one organism to another, the biomass of the latter (high trophic level) is about one-tenth of the biomass of the pre-trophic (lower trophic level). The various levels of organisms that make up the food chain, according to a certain amount of relationship, are arranged in a golden tower from large to small.

The food chain must start with green plants, so the first link is grass, grass can be eaten by grasshoppers, rabbits, and rats, so the second link has three branches, grasshoppers can be eaten by spiders, birds, frogs, rabbits can be eaten by foxes, owls, snakes, rats can also be eaten by foxes, owls, snakes, then the third link has 9 branches, spiders can be eaten by birds, frogs, birds can be eaten by owls, frogs can be eaten by owls, snakes, foxes, and snakes can be eaten by owls, so the fourth link has 3*3*(2+1+3+1) = 63 articles.

To sum up, there are a total of 63 food chains.

15 food chains.

Don't have a diagram?

Wow, those people are so powerful, and they have seen a lot.

In this question, only grass is produced by grass, insects, rabbits, and mice are primary consumers, and foxes, spiders, insectivorous birds, and owls are secondary consumers. Insects can be preyed upon by birds and spiders, and spiders can be preyed upon by birds, so three food chains can be written through insects, both.

1) Grass, insects, spiders, birds.

2) Grass, insects, spiders.

3) Grass, insects, birds.

The rabbit is only preyed upon by foxes, so there is only one food chain in which it participates, i.e. 1) grass, rabbit, and fox.

Foxes and owls prey on mice, so there are two food chains that pass through mice, namely 1) grass, rats, and foxes 2) grass, rats, and owlsIn summary, there are six food chains that can be identified in this question.
