Green plants on our planet fed by photosynthesis, ie sunlight, carbon dioxide and water.
But there are those that are not averse to diversify the diet of "live food" - the so-called predatory or carnivorous plants.
As the name suggests, insectivoresPlants, other than normal photosynthesis, feed on insects, sometimes even frogs and lizards. They are represented by more than 600 species belonging to 19 families.
Grow carnivorous plants, as a rule, on acid soils poor in minerals, and the lack of nitrogen, potassium, phosphorus, they make of the animal feed.
Carnivorous plants can be divided into twolarge groups according to the type of trapping devices - active and passive. Passive secrete sticky substances that keep insects, or have cavities - jugs, bubbles, once in production that can not get out and digested.
Active plant move to catch and hold the food. In their arsenal of traps in the form of traps and crab claws, collapsing pitchers, folding sticky leaves.
Carnivorous plants, despite their exotic, spread almost all over the world, from the temperate latitudes to equatorial - only in the CIS their lives 18 species.
Sundew live mostly in Australia, butmeet their representatives on the wetlands of the temperate zone. sundew leaves are covered with fine hairs at the end of each - a drop of sticky secretion, similar to dew. When an insect, attracted by the smell, adheres to the drop, plant leaf curls around its prey and digest.
Great contribution to the study of the carnivorous plants made famous naturalist Charles Darwin. In 1875 he published the book "Carnivorous plants", which summed up the results of fifteen years of research.
Venus Flytrap different interesting Trappersdevice - two flaps with long hairs on the edge of the trap like a slam when an insect lands between them. Digestion production takes about ten days. Flycatcher is able to distinguish the small foreign objects from living creatures, and works only on the latter.
Venus Flytrap may contain house atnecessary conditions are met - good lighting and humidity, soil composition, and, of course, live food. But please, do not overfeed the plant - it can lead to its destruction.
Nepentisy otherwise called kuvshinochnikami duetrapping devices. At the ends of these long leaves of vines reaching 20 meters, are bright jugs. Attracted by the smell of insects crawling on the edge, often fall to the bottom of the jug, and, not being able to get on a slippery surface, are digested.
