An example of predation in nature

By type of food, all living organisms are divided into autotrophs and heterotrophs. The first include plants and some bacteria that receive organic substances by photosynthesis or chemosynthesis. Heterotrophs are those organisms that consume already prepared organic compounds. These include mushrooms and animals. The latter are herbivorous or carnivorous.

Who are predators?

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

Animals-predators

All animals are divided into unicellular and multicellular. The latter are represented by such basic types as Causes, Worms, Molluscs, 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 desks: Crustaceans, Arachnids, Centipedes and Insects. A vivid example of predation in arthropods is a mantis. He can hunt small lizards, frogs and even birds and rodents. Beetle is also an example of predation in arthropods. It feeds on other insects, earthworms, mollusks, and larvae of various beetles. The fly-rod also leads a predatory life: it eats dragonflies, wasps, beetles. Almost all spiders also feed on insects, mostly flies. Spiders have the largest tarantulas and tarantulas. They have poison, with which they paralyze their victims. The first, except birds, can eat rats and other large rodents. The second mainly consumes large insects, such as ground beetles, various beetles, crickets, as well as caterpillars and larvae. A vivid example of predation in centipedes - scolopendra.

Predator Fish

Fish, fed by other large representatives of fauna, are both freshwater and marine. The first include pike, pike perch, perch, ruff. Pike is the largest freshwater predator, its weight can reach more than thirty kilograms. It eats smaller fish.

Sudak is also an example of predation in freshwater fish. It is also large, its weight is twenty kilograms, and its average length is 130 cm. Its diet consists of smaller predators: ruffs, roaches, as well as gobies, minnows and other small fish. Among marine predatory fish , a large white shark (carharadona) and barracuda are isolated. The first - the largest predatory fish in the world, it consumes 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 length is on average two meters. The main part of their diet consists of shrimp, squid, smaller fish. This fish is also called sea pike.

World of birds

The lifestyle and mode of feeding of most large birds is predation. Examples of animals of this class that hunt other living creatures: hawks, golden eagles, falcons, owls, snake eaters, kites, condors, eagles, kestrel.

Predators among mammals

This class is divided into twenty-one squads. Predatory animals of this group stand out in the eponymous detachment. To him belong mainly all well-known families, there are only thirteen of them: Dogs, Cat, Bear, Hyena, Cuny, Panda, Skunk, True Seals, Eared Seals, Walrus, Viverra, Madagascar viver, Nandinievye. Dogs include dogs, wolves, foxes, arctic foxes, jackals. The diet of all these animals consists mainly of small mammals, for example, rabbits, rodents, and also from birds. Some of them feed on carrion - they are jackals, wolves. To the cat belong tigers, lions, manulas, leopards, caracals, ocelots, lynxes, etc. They eat small mammals, mostly rodents, sometimes eat fish, insects. The bear menu can include both meat food and vegetable: berries, other fruits, roots of different plants. Seals and walruses hunt fish and some invertebrates. To viverrovymi and include animals such as genetics, African civets. They feed on birds, small animals, birds, invertebrates, bird eggs. The family of Madagascar viverr includes various kinds of mungo. Their menu includes insects and scorpions. To nandinievym refers to a single species - palm civet. She hunts mice and rats, large insects. The family of Kunya includes martens, badgers, mink, ferrets, they eat chicks and bird eggs.

Examples of predation in the plant world

Most of the plants are autotrophs. They extract their nutrients exclusively through photosynthesis, in which, absorbing solar energy, carbon dioxide and water, they receive organic substances (mainly glucose) from them and release oxygen as a by-product. But among them there are predators that feed on insects, since where they dwell there is not enough light to live only through photosynthesis. These include venus flycatchers, sundewers, non-panthers, and sarracenia.
