By type of food all living organisms are divided into autotrophs and heterotrophs.The former include plants and some bacteria, organic substances which are obtained by chemical synthesis or photosynthesis.Heterotrophs - those organisms that consume ready-made organic compounds.These include fungi and animals.Recent are herbivores or carnivores.
Who are the predators?
are living organisms that hunt and eat other creatures.Such animals are, bacteria and even some plants.
Animal predators
All animals are divided into unicellular and multicellular.The latter are represented by such basic types as Coelenterates, worms, mollusks, arthropods, echinoderms, chordal.By chordates include fish, birds, reptiles, amphibians and mammals.Examples of predation in nature exist in each of the classes of animals.
Predatory arthropods
This type includes such offices: Crustaceans, spiders, centipedes and insects.A striking example of predatory arthropods - mantis.He can hunt for small lizards, frogs and even birds and rodents.Beetle - as an example of predatory arthropods.It feeds on other insects, earthworms, mollusks, larvae of various beetles.Fly-asilidae also leads a predatory lifestyle, she eats dragonflies, wasps, beetles horses.Almost all spiders also eat insects, mainly flies.Spiders are the largest tarantulas and tarantula.They have venom with which they paralyze their victims.First, except for birds, can eat rats and other large rodents.The second generally eat more insects such as ground beetles, various beetles, crickets and caterpillars and larvae.A striking example of predation from centipedes - centipede.
Fish predators
fish eating other major representatives of fauna are both freshwater and marine.The former include pike, perch, perches, ruffs.Pike - the largest freshwater predator, it can weigh more than thirty kilograms.It feeds on smaller fish.
Pike - as an example of predation in freshwater fish.He too large, its weight is twenty kilograms, and the average length - 130 cm. Its diet consists of smaller predators: ruff, roach and calves, minnows and other small fish.Among marine predatory fish isolated great white shark (karharadona) and barracuda.The first - the largest predatory fish in the world, she eats sea lions, 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.Barracuda also reach impressive dimensions - the length of an average of two meters.The main part of their diet consists of shrimp, squid, smaller fish.This fish is also called sea pike.
World birds
lifestyle and way of eating most of the large birds - predation.Examples of this class of animals that prey on other living things: hawks, eagles, falcons, owls, toed snake-eagle, vultures, condors, eagles, kestrels.
Predators among mammals
This class is divided into twenty-one squad.Carnivorous animals in this group stand out in the eponymous squad.To him belong mostly to see family, a total of thirteen - a dogs Cat, Bear, Hyenas, Cunha, ailuridae, Skunsovye, true seals, eared seals, Walrus, civets, Madagascar civets, Nandinievye.By canids include dogs, wolves, foxes, arctic foxes, jackals.All these animals diet consists mainly of small mammals, such as rabbits, rodents, and birds.Some of them are scavengers - a jackals, wolves.For feline include tigers, lions, Man'ula, leopards, caracals, ocelots, bobcats, and so on. D. They eat small mammals, mostly rodents sometimes eat fish, insects.The menu may include both bear meat diet, and vegetable: berries, other fruits, roots of various plants.Seals and walruses prey on fish and some invertebrates.To include civets and animals such as genets, African Civet.They feed on birds, small animals, birds, invertebrates, bird eggs.Madagascar civets family includes various types of Mungo.Their menu consists of insects and scorpions.By nandinievym is only one species - palm Viverra.It hunts for mice and rats, large insects.The family Cunha includes martens, badgers, minks, ferrets, they eat chicks and bird eggs.
Examples predation in the plant world
Most of the plants are autotrophs.They obtain their nutrients exclusively by means of photosynthesis, in which, for absorbing solar energy, carbon dioxide and water, are prepared from organic substances (mostly glucose) and release oxygen as a byproduct.But there are also predators that feed on insects, as where they live, not enough light to live only through photosynthesis.These include the Venus flytrap, sundew, Nepenthes, Sarracenia.
