Best answer: Why does the biodiversity of an ecosystem affect its resilience quizlet?

When species are more diverse their likelihood of surviving increases. … Species diversity would show more resilience because the organisms are more likely to inherit traits that can help them survive. If there’s little diversity then the species won’t be able to adapt to change.

Why does 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.

How is biodiversity related to ecosystem resilience quizlet?

Species diversity is related to genetic diversity. The more genetically diverse a species is, the more resilient it is. … The more species diversity, the more resilient the ecosystem.

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.

Does biodiversity decrease an ecosystems resilience?

In conclusion, the works done by Isbel et al., Steneck et al., and Oliver et al., have led us to answer that the biodiversity of an ecosystem affects the resilience of an ecosystem.

Why is resilience important in an ecosystem?

Increasing resilience can reduce the risk that the system will cross critical thresholds and undergo a detrimental regime shift. … System resilience can play an important role in maintaining conditions that will sustain the provision of ecosystem services that contribute to human well-being.

How does biodiversity affect ecosystem stability?

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.

What makes an ecosystem resilient quizlet?

When a disturbance affects communities and populations but not the overall flow of energy and matter it is said to have high resistance. Resilience- The rate at which an ecosystem returns to its original state after a disturbance. Resilience of an ecosystem ensures that it will continue to provide benefits to humans.

What is the most important factor in an ecosystems resilience?

Ecologists can deem heterogeneity and diversity as individual components. Further, redundancy and modularity are deemed to be important factors determining the resilience of an ecosystem.

How does habitat loss affect generalist species?

If habitat loss happens and it changes, the specific things they are used to eating will go away. Generalist species would just move to a different habitat because they can adapt easily to different climates. Can you think of a reason why it might be advantageous to be a specialist?

Does biodiversity make ecosystems more resilient?

Greater biodiversity makes ecosystems more resistant to climate change. … The productivity of low–diversity ecosystems, those with one or two species, was reduced by about 50 percent on average during extreme climatic events.

Why an ecosystem with greater biodiversity is 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.

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.

What happens to ecosystems and biodiversity when the environment changes?

Ecosystem perturbations driven by climate change have direct human impacts, including reduced water supply and quality, the loss of iconic species and landscapes, distorted rhythms of nature, and the potential for extreme events to overwhelm the regulating services of ecosystems.

How is the resilience of an ecosystem different from its resistance to disturbance?

Resistance is the ability for an ecosystem to remain unchanged when being subjected to a disturbance or disturbances. … Resilience is the ability and rate of an ecosystem to recover from a disturbance and return to its pre-disturbed state.

How biodiversity can help maintain a viable ecosystem for resilience to stress?

Ecosystems with a high degree of biodiversity can cope with more stress, such as higher temperatures or increasing salt concentrations, than those with less biodiversity. They can also maintain their services for longer, as botanists and ecologists have discovered.
