An example of predation in nature

By type of food, all living organisms are divided intoautotrophs and heterotrophs. The first includes plants and some bacteria that receive organic matter through photosynthesis or chemosynthesis. Heterotrophs - those organisms that eat ready-made organic compounds. These include mushrooms and animals. The latter are herbivores or carnivores.

Who are the predators?

These are living organisms that hunt and eat other creatures. These are animals, bacteria, and even some plants.

Predatory animals

All animals are divided into single-celled andmulticellular. The latter are represented by such basic types as the Intestinal Cavity, Worms, Mollusks, Arthropods, Echinoderms, Chordates. Chordates include fish, birds, reptiles, amphibians, mammals. Examples of predation in nature exist in each of the classes of animals.

Predatory arthropods

This type includes such cash registers:Crustaceans, Arachnids, Centipedes and Insects. A vivid example of predation in arthropods is the mantis. He can hunt small lizards, frogs and even birds and rodents. Ground beetle is also an example of predation in arthropods. It eats other insects, earthworms, mollusks, larvae of various beetles. The fly-ktyr also leads a predatory way of life: it eats dragonflies, wasps, racehorse beetles. Almost all spiders also feed on insects, mostly flies. In spiders, tarantulas and tarantulas are the largest. They have a poison with which they paralyze their victims. The first, except for birds, can eat rats and other large rodents. The second mainly eats large insects, such as ground beetles, various beetles, crickets, as well as caterpillars and larvae. A striking example of predation in centipedes is skolopendra.

Predator fish

Fish feeding on other major representativesfauna are both freshwater and marine. The first are pike, perch, perch, ruff. Pike is the largest freshwater predator, its weight can reach more than thirty kilograms. She eats smaller fish.

Sudak is also an example of freshwater predation.fishes. It is also large, its weight is twenty kilograms, and the average length is 130 cm. Its diet consists of smaller predators: ruffs, roach, and also gobies, minnows and other small fish. Among the marine predatory fish emit the great white shark (carharadona) and barracuda. The first one is the largest predatory fish in the world, it eats fur seals, seals, sea otters, sea turtles, tuna, mackerel, sea bass. In some cases it can attack people. White sharks have several rows of teeth, the total number of which can reach 1500 pieces. Barracudas also reach impressive sizes - their average length is two meters. The main part of their diet consists of shrimp, squid, smaller fish. This fish is also called sea pike.

World of birds

Lifestyle and nutritionbirds - predation. Examples of animals of this class that hunt other living creatures: hawks, golden eagles, falcons, owls, snake-eaters, kites, condors, eagles, kestrels.

Predators among mammals

This class is divided into twenty-one squad.Predatory animals of this group are allocated in the squad of the same name. Mainly known families belong to it, only thirteen of them are Dog, Cat, Bear, Hyena, Cunha, Panda, Skunk, Real seals, Eared seals, Walrus, Viver rovers, Madagascar wivera, Nandinia. Dogs, wolves, foxes, arctic foxes, jackals are dog dogs.

The diet of all these animals consists mainly ofsmall mammals, for example, hares, rodents, and also from birds. Some of them eat carrion - it's jackals, wolves. Tigers, lions, manulas, leopards, caracals, ocelots, lynxes, etc. belong to the cat. They eat small mammals, mainly rodents, sometimes feed on fish and insects. The bear menu can include both meat and vegetable food: berries, other fruits, roots of different plants. Seals and walruses hunt for fish and some invertebrates. Such animals as genetas, African civets are also considered to be viverrians. They feed on birds, small animals, birds, invertebrates, and bird eggs. The family of the Madagascar wyverr includesdifferent types of mungo. Their menu includes insects and scorpions. Nandinium refers to a single species - palm civet. She hunts mice and rats, large insects. The marten, badger, mink, ferret enter the Cunha family, they eat chicks and bird eggs.

Examples of predation in the plant world

Most of the plants are autotrophs.They extract nutrients only through photosynthesis, in which, absorbing solar energy, carbon dioxide and water, they extract organic matter (mainly glucose) from them and release oxygen as a by-product.

But among them there are predators that feedinsects, because where they live, there is not enough light to live only through photosynthesis. These include Venus flytrap, sundew, nepenthes, sarratsenii.
