Question

How nutrient cycling affects the growth of Redbud trees?

Answer 1

Not only redbud trees, but nutrient recycling is important for the growth of all the organisms.

We will discuss this in context of plants (redbud trees) only.

Plant harvest solar energy and take up carbon dioxide to synthesise sugar in a process called as photosynthesis.

In this process, water is also used and splitted to produce protons and Oxygen gas.

Oxygen gas is released into the atmosphere and taken up by animals and plants. Both animals and plants show aerobic cellular respiration in the presence of oxygen for The breakdown of glucose to synthesise ATP.

The breakdown of glucose leads to the evolution of carbon dioxide and water. This carbon dioxide is released into the atmosphere which is then again taken up by the plants to synthesise sugar molecules during photosynthesis.

This is one of the steps of nutrient Recycling in plants, which involves photosynthesis and respiration.

The Other step is decomposition. Whenever plants die, they fall on the ground. They are acted upon by various decomposers like bacteria and fungus. The decomposers breakdown complex organic molecules present in the dead plant bodies into simple inorganic molecules like water and carbon dioxide. Carbon dioxide is against released into the atmosphere and is used by other plants for photosynthesis.

Water is always reduced to evolve Oxygen gas so that it can be used by organisms showing aerobic respiration.

The third step of nutrient recycling which is seen in some plants like the members of family fabaceae is the recycling of element nitrogen. The bacteria present in the roots of these plants is able to undertake nitrogen fixation. This bacteria takes up atmospheric nitrogen and convert it into nitrate and nitrite which is used by the plants. The nitrate and nitrite are incorporated into nucleic acids and proteins and when the plants die, the decomposers help in the release of Nitrogen oxides back into the environment.

All of these nutrient recycling is present in redbud trees and because it is the member of family pharmacy, it will also so nitrogen recycling.

Nutrient cycling is related to the cycling of mainly carbon, hydrogen and oxygen. Other nutrients like Phosphorus, Sulphur, nitrogen are also involved.

Please give me a good rating.
