Who eats whom Food is one of the most important needs for animal survival, and here the little moves

Grass (rose) - aphid - ladybug - bird leaf - earthworm - bird.

King cobras, praying mantises, cannibals.

A lot of them, most of them don't survive by eating their own kind, but they eat their own kind, and King Cobra basically only eats other small snakes.

Komodo dragons.

People also survive by "eating" their own kind.

According to the principle of energy diminishing, it is impossible to satisfy the continuation of the species by simply eating the same kind. Occasionally eat a lot of animals of the same kind, including humans.

In addition to "carnivorous" plants, there are also plants that live by parasitizing other plants or trees. The "food" of these parasitic plants is actually plants. For example, dodder seeds.

Cuscuta is parasitic on cranberry or saddle vine, inserted into the tissue of cranberry or saddle vine through small tentacles, and sucks nutrients from cranberry or saddle vine.

Finally, don't you also feel that plants are amazing? Do you like these plants?

The food of plants is soil, rain and sunlight, plus the fresh air of nature, these are the natural foods of plants.

The main food of plants is carbon dioxide in the air, as well as sunlight and water.

Of course, there are various elements of the earth's surface.

When plants get this food, they produce oxygen to supply all kinds of creatures on the ground.

The food of plants is fertile soil, and the soil must be chosen correctly. Sufficient moisture, sufficient sunlight, and good air environment. Increase fertilizer appropriately. This is the best food for plants.

Sunlight allows plants to photosynthesize, allowing them to produce energy for their own use, groundwater and rain to feed them, and plants to eat when their leaves have decayed.

The need for nutrition in the life of living organisms is a common characteristic of biological sources, so every kind of hail and fool must obtain the food it needs from the environment in which it lives

So the answer is:

Animal cells do not have chloroplasts, cannot photosynthesize, cannot make organic matter on their own, and must ingest food (organic matter) from the outside world to live, so they belong to heterotrophs; The feces or their remains excreted by animals can also release carbon dioxide, nitrogen-containing inorganic salts and other substances through the decomposition of saprophytic bacteria

So the answer is: heterotrophs; Saprophytic bacteria

Each animal has different requirements for the living environment, but the survival of any animal is inseparable from food, water and shelter. The three basic elements, food and water provide energy for the animal, and concealment provides the environment that the animal needs for physiology, reproduction and survival.

There are many different living environments suitable for wild animals, and for the vast majority of wild animals, the natural environment without the influence of human activities is the most suitable home for their survival. The reasons for the endangerment of wild animals are both natural and man-made factors, and human economic activities are the most fundamental reasons for the endangerment of wild animals today.

The soil provides a habitat for animals to survive.

The contribution of soil is to provide nutrients and water for plants, habitat for animals, and shelter and raw materials for humans to make things.

The food that animals need is supplied by these substances, which are then broken down into energy by the body.

Some of the food he needed at noon was provided to him in some ways to stay alive.
