Carnivorous plants

Carnivorous plants overview of habitats and food idiosyncrasies at nutrient-poor locations (eg moor), some species can invade a method to find the lack of nutrients (especially nitrogen and compounds) commercially. They catch and digest animal prey. Most insects, though the larger tropical species occasionally catch a frog, or the various aquatic species accordingly Krustazeen or small fish. These animals is for growth and prosperity of the plant in its barren habitat is very supportive, but not vital. A carnivorous plant is so even after prolonged almost not a cure, it is all things. The trapping this carnivoren are varied and refined. The booty is in the digestive juices drowned, absorbed or in the case bears a kind of fixed. The individual families are basically divided according to their fishing. Description of individual families, their habitats and lifestyles. For the ones subgroup, Sarracenia, the individual pitchers in the form of a rosette arranged. This structure, we will still find many times. This example is the jug from a thin tube and upwards is becoming more widely, with most species to a piece about Mark Grand Opening. This is a kind of shield around, which in some ways a lid is formed. In the center of the rosette of the flowers. They sit at a long stalks high above the rest of the plant. Probably avoids the plant so that they are their own pollinator. The insect catch will now proceed as follows: The opening of the pitchers is slightly raised and often colorful, but the lid is usually brightly colored. Of this, and the scent of nectar plant insects are attracted. In search of nectar, they are on the edge of the hole down, then hike into the interior of the pot. This is designed so that you can while the bottom - even very quickly, because the interior walls are smooth and slippery - but not upward. Prevent the damp interior walls and strong, hard hair, in such an angle from the tower walls that overcoming impossible.
Finally, land animals in the digestive fluid, which is at the bottom of the pot has accumulated. Regarding the way these individual species developed different ways of eating. Some distinguished from the secretions done here serves as the cover and rain is designed so that a dilution of the secretions in prevented rainwater. Others need the rain as a dilution of their concentrated secretions. This closes the lid is not opening. The digestive secretions flow in a zone, which is deep in the cup, with hair below the occupied region. The juices, then the secretion from the glands are similar to the animal digestive enzymes. In the Sarracenia species but are always bacteria in the digestive involved. For a few types of bacteria even take over the whole digestive work. This system is usually insects, like flies, bees, mosquitoes, etc., for the victims. Occasionally has a spacious opening but once the happiness, an insect fangenden tree frog, or even larger insect smaller toads to catch. As if all this is still not common enough to have some Sarracenia species (Darlingtonia), nor various extra traps idea. With this type of cover protects the hole before the rain. He is shaped so that the plant looks like an attacking cobra (In its North American distribution area will be called Cobra Lily).
These snake-like appearance is an outgrowth of the opening (looks like a snake tongue) even more, he is bright-colored and acts as a runway for insect prey. The lid completely obscured the entrance. Normally he would be so obscured, and to become a place in which no reasonable insect would stop. Therefore, the plant cover in their tissues transparently spots, a sort of window developed. Now is the entrance illuminated. Another effect: An insect that wants to get out, crawls to these transparent stains, in the assumption that it is here to the outcome of the whole affair. This is obviously not out. Rather, the insect crawls tired. Plumpst and finally into the digestive fluid. Another interesting representative of the Can Nepenthes plants, with over 60 sub-species residing on Borneo and the surrounding area. These plants live on the earth’s surface or epiphytic in rain forests, savannas and dry, sandy hill areas. Nepenthes has long, slender, leaves sworts like with serrated edge, the tips in tendrils semester. This keep the plant in the rest of vegetation established. At the ends of tendrils formed the opening, with a rain equipped. The cans are in most types of colorful designs. The flowers are small and uninteresting and are in a tuft at the tip of the stem. Naturally, this plant has a nasty trick from camp: From the stems of the plant, on the leaves and tendrils, up to because pitchers are small droplets of nectar secreted.
