Sample Essays, Example Research Papers and Tips Posted on by azseo Biodiversity vs Species Diversity Essay Biological diversity includes all organisms, species and populations living on earth or in a particular area.
In other words, biodiversity reflects full diversity and variety of life on Earth. Biodiversity shows how healthy an ecosystem is — the healthier an ecosystem, the larger its biodiversity.
Biodiversity has three levels — genetic, species and ecosystem diversity. A species is a group of plants or animals that are similar and able to breed and produce offspring under natural conditions. Species diversity is the number of different species of living things living in a particular area and all the differences within and between populations of species, as well as between different species.
Ecosystems change all the time — some of them faster, and some of them slower. Ecological succession is the changing cycle of communities or species that live in an ecosystem during a particular time period.
There any minor changes even in relatively stable ecosystems. At any point of time, any ecosystem can become a subject to external forces, which can restart succession process. First, pioneer species come to places, where there were no living beings before them.
In such cases, it is called primary succession. Pioneer species are usually autotrophs, photosynthetic bacteria and lichen and they can find, for example, bare rocks to occupy. Primary succession can also occur in the places after volcano eruption, glacier retreat, fire or flood.
Pioneer species should be able to continue to exist under tough conditions. For example, lichen are able to overcome nearly drying out.
Pioneer species change their microenvironment, which allows new species to come. After lichen, mosses usually come next.
As primitive species colonize the area, they increase the fertility of the soil, become decaying matter and leave minerals. Afterwards, ferns can appear, followed by flowers and grass. Grasses prevent water from running off, keeping it trapped in the soil.
As a next stage, trees and bushes come. Larger trees bring shade and hide smaller tries from sunlight. Consequently, some smaller plants die out.
Succession can also occur, when one community comes instead of another one. Such successions are much more common.Essay on the Importance of Biodiversity. (example: tropical rain forest) are more productive than ecosystems with lower biodiversity (example: temperate forests). Biodiversity is essential for maintenance and health of ecosystems through the occurrence of various checks, controls, negative and positive feed backs.
