Essay on insectivorous plants

Some are mountainous and rocky while others are pebbly or full of sand dunes. Some become baking hot under the sun whereas others are bitterly cold but there is one thing common about all of them and that is the hostile conditions which prevail making the survival of flora and fauna a complete admirable task.

Essay on insectivorous plants

Insectivorous plants Drosera capensisthe Cape sundew, bends on trapping an insect. Insectivorous plants are plants that derive some of their nutrients from trapping and consuming animals or protozoan.

The benefit they derive from their catch varies considerably; in some species it might include a small part of their nutrient intake and in others it might be an indispensable source of nutrients.

Introduction to Evolutionary Biology

Their prey animals typically, but not exclusively, comprise insects and other arthropods. Plants highly adapted to reliance on animal food use a variety of mechanisms to secure their prey, such as pitfalls, sticky surfaces, hair-trigger snaps, bladder-traps, entangling furriness, and lobster-pot trap mechanisms.

The list is far from complete, and some plants, such as Roridula species, exploit the prey organisms mainly in a mutualistic relationship with other creatures, such as resident organisms that contribute to the digestion of prey. In particular animal prey organisms supply carnivorous plants with nitrogen, but they also are important sources of various other soluble minerals, such as potassium and trace elements that are in short supply in environments where the plants flourish.

This gives them a decisive advantage over other plants, whereas in nutrient-rich soils they tend to be out-competed by plants adapted to aggressive growth where nutrient supplies are not the major constraints. Technically these plants are not strictly insectivorous, as they consume any animal that they can secure and consume; the distinction is trivial, however, because not many primarily insectivorous organisms exclusively consume insects.

Most of those that do have such a restrictive diet, such as certain parasitoids and hunting waspsare specialised to exploit particular species, not insects in general.

Indeed, much as large mantids and spiders will do, the larger varieties of pitcher plant have been known to consume vertebrates such as small rodents and lizards.Supposedly from *Origin of Species*, this one is all over the web (and even in a stone floor) but is from a management studies text.

They are often called insectivorous plants, because they usually trap insects. Since they get some of their food from animals, carnivorous plants can grow in places where the soil is thin, or poor in nutrients.

This is true for soils with little nitrogen, such as acidic bogs and rock outcrops. Jun 09,  · The first book on these plants was written by Charles Darwin, in , “Insectivorous Plants”. After further discoveries and research, it is believed that these carnivorous properties evolved on six separate occasions, from five different orders of flowering plants.
