By genetic modification and evolutionary processes, biodiversity is increased and decreased by habitat loss, population reduction and extinction. The number and relative abundance of species present in a given biological organization is simply species diversity (population, ecosystem, Earth).

Genetic Modification is a procedure to change the qualities of a plant, creature or miniature life form by moving a bit of DNA from one living being to an alternate living being. This is done through focused expulsion of the ideal qualities from the DNA of one living being and adding them to the next living being. This strategy has for instance been utilized to create growths and microorganisms that produce drugs.

Evolution is the cycle by which current creatures have dropped from old progenitors. Evolution is liable for both the surprising similitude we see over all life and the astonishing variety of that life.

Explanation:

Evolution is change in the heritable qualities of organic populaces over progressive ages. These attributes are the statements of qualities that are given from parent to posterity during generation. Various attributes will in general exist inside some random populace because of transformation, hereditary recombination and different wellsprings of hereditary variety. Evolution happens when transformative cycles, for example, regular choice (counting sexual choice) and hereditary float follow up on this variety, bringing about specific qualities getting more normal or uncommon inside a populace.

It is this cycle of development that has offered ascend to biodiversity at each degree of natural association, including the degrees of species, singular life forms and atoms.

good thing- during decomposition the organic molecules in organic matter are broken down into simpler organic molecules that require further decomposition or into mineralised nutrients

bad thing- it can be harmful in crop productivity

a physical change is being made.
