Why is an ecosystem with more biodiversity more stable than an ecosystem with less biodiversity?

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 is an ecosystem with greater biodiversity more resilient than an ecosystem with less biodiversity?

Explain why an ecosystem with greater biodiversity is more resilient then an ecosystem with less biodiversity. AN ecosystem with greater biodiversity has more organisms that preform similar functions so it can recover faster from disturbances than an ecosystem with fewer organisms.

Why is an ecosystem with a higher biodiversity more stable?

Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.

Is it better to have low biodiversity or high biodiversity?

The biodiversity of species, or species richness, is often used as a measure of ecological health. High biodiversity, with many species present, is good. It usually means that an ecosystem is healthy and relatively undisturbed by humans. Low biodiversity is characteristic of an unhealthy or degraded environment.

Why is an ecosystem with higher levels of biodiversity more stable than an ecosystem with lower levels of biodiversity quizlet?

An ecosystem with a high level of species diversity such as a rainforest (high productivity) is much more stable than an ecosystem with low biodiversity such as a desert (low productivity). All ecosystems are complex and all species have a niche. … Species surviving in one area can be used to repopulate other areas.

Why are ecosystems with more biodiversity healthier and more resilient?

This research showed that diverse communities are more stable because they exhibit resistance during extreme climate events.” … Instead, resistance to change clearly superseded resilience as the main mechanism by which biodiversity helps to preserve ecosystem stability in the face of climatic extremes, he said.

Why does the biodiversity of an ecosystem affect its resilience?

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.

What is stability in biodiversity?

Biodiversity and Ecosystem Stability

Ecosystem stability is the ability of an ecosystem to maintain a steady state, even after a stress or disturbance has occurred.

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.

Which ecosystem is most stable?

Oceans is stable ecosystems since it stays unchanged over the long term. Various natural geological and anthropogenic forces build and damage mountains, deserts and forests but oceans have remained stable over the long history of the Earth.

How are ecosystems with high biodiversity better than ecosystems with limited biodiversity?

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.

What is the difference between high and low biodiversity and high and low stability?

When an ecosystem has high biodiversity it is always more stable than an ecosystem that has low biodiversity. … Low biodiversity is when there are a few prominent species and a low number of other species within the habitat. High biodiversity is a habitat or ecosystem that has a high number of different species.

When might an increase in biodiversity lead to a decrease in the stability of an ecosystem?

An increase in biodiversity usually leads to an increased stability, but in the case of an invasive species it would lead to a decreased stability.

Which ecosystem has high biodiversity low biodiversity?

Estuarine areas (where rivers meet seas and oceans) have high biodiversity compared to other areas. Trophical rainforests are rich in terms of biodiversity. Arid and semiarid areas have low biodiversity. Deserts, for example, contain limited numbers of species.

How can an increase in biodiversity lead to an increase in ecosystem stability is a more biodiverse ecosystem is not subject to change?

How can an increase in biodiversity lead to an increase in ecosystem stability? … A more biodiverse ecosystem has a higher chance of adapting to species changes.

When might an increase in biodiversity lead to a decrease in the stability of an ecosystem quizlet?

An increase in biodiversity usually leads to an increased stability, but in the case of an invasive species it would lead to a decreased stability. Adding an organism to a food chain does not affect the other members of the food chain, but removing an organism does.
