Do all ecosystems return to the original climax community following a disturbance Why or why not?

Do all ecosystems return to the original climax community following a disturbance?

Do ecosystems return to “normal” following a disturbance? Secondary succession in healthy ecosystems following natural disturbances often reproduces the original climax community. Ecosystems may or may not recover from extensive human-caused disturbances.

Is the original climax community in an ecosystem more likely to be restored after a natural disturbance or a human-caused disturbance explain your answer your answer?

Why or why not? No original climax communities are not always restored. Succession does not always follow the same path. Some climax communities are disturbed so often that they cannot return to their original state due to natural disasters such as volcanic eruptions, wildfires, mudslides, hurricanes etc.

Can some ecosystems recover after a disturbance?

The change a terrestrial ecosystem experiences as it recovers from a disturbance depends on the intensity and magnitude of the disturbance. The major mechanisms of recovery in such ecosystems are primary and secondary succession. Primary succession occurs in a landscape that previously was devoid of life.

What happens to an ecosystem after a disturbance?

Whenever an ecosystem is affected by a substantial disturbance event, individuals and even entire species may be weakened or killed off. Other ecological damages can also occur, such as changes in hydrologic processes or soil contamination.

Does secondary succession restore original climax community?

Secondary succession may not restore the original climax community when the soil structure and microbiome is damaged. Julie is studying the clearing of tropical rain forests in Brazil. The land is being cleared for farming, but the poor quality of the soil limits the productivity of the farms.

What environmental factors may affect the type of climax community that develops in an ecosystem?

In addition to trees, each successive community harbors many other life forms, with the greatest diversity populating the climax community. Similar ecological zonings occur among marine flora and fauna, dependent on such environmental factors as bottom composition, availability of light, and degree of salinity.

How does a climax community differ from a successional community?

How does a climax community differ from a successional community? A climax community is relatively stable, long-lasting, complex and interrelated group of many different organisms. A successional community is a stage in the successional process. You just studied 20 terms!

What is a climax community in science?

climax, in ecology, the final stage of biotic succession attainable by a plant community in an area under the environmental conditions present at a particular time.

When species that colonized for the first time on the bare area is known as?

The species colonizing an uninhabited area for the first time is referred to as the pioneer species and the dominating community is called pioneer community. Soon, a wider range of plants and animals will occupy the area until a climax community is established.

What is an ecosystem that rapidly returns to its original state after a disturbance?

APES Chapter 3 Vocab Review

A B
environmental resistance a measure of how much a disturbance can affect an ecosystem (usually in terms of energy flow)
resilience the rate at which an ecosystem returns to its original state after a disturbance. Highly resilient = returns to original state rapidly

How does disturbance affect ecological communities?

Disturbance Affects Species Diversity. (A) Species diversity is low at low disturbance frequency because of competitive exclusion. … At high disturbance frequency, species diversity is predicted to be low, because only “weedy” species that quickly colonize and reach maturity are able to survive.

How ecosystems can be restored?

Ways to restore them include reducing tillage, using more natural fertilizer and pest control, and growing more diverse crops, including trees. These steps can rebuild carbon stores in soils, making them more fertile so countries can feed their growing populations without using even more land.

What happens to an ecosystem following a disturbance explain both types of succession?

After a disturbance in which the soil has been destroyed/removed, the pioneer species will arrive first. This is a key part of primary succession. … Once the soil has formed, the ecosystem goes through the stages of ecological succession until another disturbance occurs.

How an ecosystem can reach the climax community?

In scientific ecology, climax community or climatic climax community is a historic term for a community of plants, animals, and fungi which, through the process of ecological succession in the development of vegetation in an area over time, have reached a steady state.

How has ecosystem been disturbed?

Many ecosystems are influenced by disturbances such as e.g. land-use, fragmentation, fire, floods or storms. … In particular the interaction of different disturbances and between disturbances and other stress factors (such as habitat loss, pollution or temperature change) is not yet well understood and studied.
