What is Nudation in ecological succession?

Nudation. It is the development of a bare site uninhabited by any organisms. The process is usually caused by disturbances. These factors can be either topographic (soil erosion, wind action etc); climatic (hails, storm, glaciations, fire etc.); or biotic (human activities).

What are the causes of Nudation?

The cause of nudation may be topographic (soil erosion, landslide, volcanic activity, etc), climatic and biotic (human beings and pathogens).

What is Nudation in biology?

Nudation. Ø Definition: Nudation is the development of a bare area (an area without any life form). Ø It is the first step in ecological succession.

What are two types of successions?

There are two major types of ecological succession: primary succession and secondary succession. Primary succession happens when a new patch of land is created or exposed for the first time.

What is Ecesis in ecology?

Definition of ecesis : the establishment of a plant or animal in a new habitat.

How an ecosystem regulates itself in equilibrium?

Decomposers help in returning the nutrients back into the environment. Various nutrient cycles, such as carbon, water, nitrogen and phosphorus ensure that these are continuously recycled. Intraspecific interactions such as prey and predator relationships also help in maintaining the balance of an ecosystem.

What is competition and Coaction?

Competition and Coaction: As the species aggregate within a restricted space, there happens competition for space and nutrition. Secondly, the life process of one individual is affected by the surrounding species in various ways which are known as coaction.

Who proposed Monoclimax theory?

1. Mono-climax Theory: According to the mono-climax theory of succession (Clements, 1936), every region has one climax community toward which all communities are developing. He believed that climate was the determining factor for vegetation and the climax of any area was solely a function of its climate.
