solution carnivorous plants insects to obtain nitrogen jawaban

Because there are only a limited number of genes and new genes, new abilities cannot simply be imbued within us of out of sheer necessity; the organism must alter the functions of a few genes over time, or rather, compromise a few abilities to replace them with new ones.

Carnivorous plants have been estimated to have evolved around 60-125 million years ago.

However, what made them indulge in such an immoral act of eating their own or in a sudden outburst of temper, finally eat the buggers sitting on them Honestly, Id do the same if people sat on me without acknowledging my presence.

The most coveted need: Nutrition Every organism on this planet is a survivor, and fights a battle every day.

Fitness has a broad meaning when it comes to evolutionary biology but lets say in its most primitive sense it is derived from consuming food, so an organism that eats every day stays healthy, fit, to fight another day.

The primary source of food for plants is the environment and soil that their roots clench beneath them.

They are photosynthetic organisms that transform inorganic matter from the environment into organic molecules (glucose).

Other than carbon dioxide seeping in from the air, they also require other important nutrients, which they receive from the mish-mash of water and soil.

This is the process of converting ammonia from protein decay into crucial nitrite and nitrates ions.

What if an unfortunate plant grows in a habitat that lacks these nutrients Carnivorous plants are a specialized group of plants that grow in wet, boggy, acidic soils.

The pH of the water and soil they grow in is too acidic to allow nitrification.

It seems that they compensated for this shortage with the ability to digest insects and other arthropods.

Therefore, nitrogen-devoid soil plants have evolved into carnivorous plants that can entrap and digest insects as a means of obtaining nitrates.

The Manipulation of Biological Mechanisms This type of evolution is called convergent evolution.

It is a product of strict biological restrictions imposed by nutrient-scarce ecosystems.

Beneath the inexhaustible beauty of nature lies a highly ungenerous parent.

In dire necessity, it never provides, but rather forsakes its children, forcing them to utilize what they already possess they must adapt.

In some sense, this extremely strict edification makes an organism self-sustaining and researchers think this is exactly what happened.

A team confirmed this when they successfully identified the key genomic changes that allowed some plants to adopt a carnivorous lifestyle.

Carnivorous plants realized that the creation of entirely new molecular strategies isnt necessary.

Previously existing genes could be assigned new biological functions to produce these necessary molecules.

The selection here isnt random, it is guided by externalities.

According to Professor Julio Rozas, from the Department of Genetics, Microbiology and Statistics, these plants ability to feed from animals in poor soils is the result of the action of natural selection, which independently favored several genetic changes on the same set of genes.

The First Mechanism: The Trap Natural selection operates on the scale of genes.

Genes contain the blueprint on the basis of which our body parts are manufactured.
