Best answer: Why does biodiversity make ecosystems more stable or resilient?

Generally speaking, greater species diversity (alpha diversity) leads to greater ecosystem stability. This is termed the “diversity–stability hypothesis.” An ecosystem that has a greater number of species is more likely to withstand a disturbance than an ecosystem of the same size with a lower number of species.

Why does biodiversity effect resilience or the stability of the ecosystem?

Diversity-Stability Theory

Biologically diverse communities are also more likely to contain species that confer resilience to that ecosystem because as a community accumulates species, there is a higher chance of any one of them having traits that enable them to adapt to a changing environment.

Does biodiversity make ecosystems more resilient?

A new study published in the journal Nature last week finds that ecosystems that have a greater number of species are indeed more resistant to extreme climatic events, including prolonged wet and dry periods.

Why does biodiversity make ecosystems more stable?

It has been shown that biodiversity of an area has a large impact on the ecosystem stability of that area. … This increase in complexity makes it more likely that the ecosystem will return to a stable state after a disturbance, because the ecosystem has more ways to respond to a disturbance and fix problems.

How does biodiversity make an ecosystem more sustainable resilient to survive?

Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.

Why is resilience important in biodiversity?

Resilience is a key underpinning principle of biodiversity strategies at all levels of government. … Ecological resilience is generally defined as the ability of ecosystems to resist permanent structural change and maintain ecosystem functions.

How does biodiversity contribute to climate stability?

Biodiversity – Contribution to climate stability. Vegetation influences the climate at macro and micro levels. … On smaller scales, vegetation has a moderate influence on local climates and may create quite specific microclimates. Some organisms are dependent on such microclimates for their existence.

Why is biodiversity important to ecosystem?

Biodiversity is important to humans for many reasons. … Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services.

Which ecosystem is more resilient?

Ecosystems that are more complex are more resilient, or better able to tolerate and recover from disturbances, than ecosystems that are less complex. To help illustrate why this is, imagine a complex ecosystem with many components and many interactions between those components.

How do keystone species maintain diversity in an ecosystem?

Such species help to maintain local biodiversity within a community either by controlling populations of other species that would otherwise dominate the community or by providing critical resources for a wide range of species. The name keystone species, coined by American zoologist Robert T.

How does biodiversity affect the stability of an ecosystem quizlet?

How does biodiversity affect the stability of an ecosystem? Having a number of different organisms increases the stability of an ecosystem, because a change in the population of one organism will have less effect on the population of an organism that depends on it.

Why are more complex ecosystems more stable?

The reason greater stability is found in complex ecosystems is that with more complex interactions, the ability of organisms to deal with disturbances increases.

What makes ecosystem stable?

The two key components of ecosystem stability are resilience and resistance. Resistance is an ecosystem’s ability to remain stable when confronted with a disturbance. … First is to maintain a diversity of plants and animals in an ecosystem. Humans have a tendency to simplify ecosystems to maximize one particular output.
