Which may be an indicator of a stable ecosystem?

Q. Which may be an indicator of a stable ecosystem? The fluctuations of populations of organisms can be predicted.

What are two indicators of a stable ecosystem?

Stability has two components:

Resistance – the ability of the ecosystem to continue to function without change when stressed by disturbance. Resilience – the ability of the ecosystem to recover after disturbance.

What defines a stable ecosystem?

Stability (of ecosystem) refers to the capability of a natural system to apply self—regulating mechanisms so as to return to a steady state after an outside disturbance.

What is an ecosystem indicator?

Ecosystem indicators are quantitative biological, chemical, physical, social, or economic measurements that serve as proxies of the conditions of attributes of natural and socio-economic systems (Environmental Protection Agency 2008, Kurtz et al. 2001, Landres et al. 1988, Fleishman and Murphy 2009).

What is the best indicator of a healthy ecosystem?

A commonly cited broad definition states that a healthy ecosystem has three attributes:

  • productivity,
  • resilience, and.
  • “organization” (including biodiversity).

What type of ecosystem is most stable?

The ocean is the most stable ecosystem. It is stable due to its natural liquid nature (saline), dissolved oxygen, light and temperature. Note: An environment is considered to be stable when its structure and function remain unchanged for a long period of time.

Which characteristic do stable ecosystems tend to have?

Stability Important

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. Resilience is the speed at which an ecosystem recovers from a disturbance.

How do you know if an ecosystem is stable?

An ecosystem is said to possess ecological stability (or equilibrium) if it is capable of returning to its equilibrium state after a perturbation (a capacity known as resilience) or does not experience unexpected large changes in its characteristics across time.

What primarily maintains ecosystem stability?

Overall, biodiversity is very important, because it helps maintain ecosystem stability, which is the ability of an ecosystem to maintain a steady state, even after a stress or disturbance has occurred.

What does stability mean?

Definition of stability

1 : the quality, state, or degree of being stable: such as. a : the strength to stand or endure : firmness. b : the property of a body that causes it when disturbed from a condition of equilibrium or steady motion to develop forces or moments that restore the original condition.

What is the name of the indicator ECO?

1 Eco-Indicator 99 (Impact Points) Eco-indicator 99 (EI99) is a top-down model that initially identifies three environmental damage endpoints: human health, ecosystem quality, and resources.

What are ecological indicators examples?

Ecological indicators are biological assemblages or taxa that by their presence or condition indicate something about the environment. For example, the presence or absence of patches of plants or bare soil can be used as indicators of the state of the health of the landscape.

What are the 5 environmental indicators?

Five important global-scale environmental indicators are biological diversity, food production, average global surface temperature and atmospheric CO concentrations, human population, and resource depletion.

What are indicators of ecosystem health?

Ecosystem health indicators are measures which help us to understand where action should be taken to restore ecosystem health and associated benefits. Condition indicators tell us whether an ecosystem is in a good state. They include indicators of habitat, species and resources, such as water and carbon.

What does indicator species tell us about the health of an ecosystem?

Indicator species (IS) are animals, plants, or microorganism used to monitor changes in our environment. For example, they can tell us about the impact of pollution on an ecosystem, or how well an impaired environment is being managed or restored.

What is an indicator of the health of an ecosystem by the variation of life that exists in it known as?

Biodiversity, n. The variability among living organisms on the earth, including the variability within and between species and within and between ecosystems. … Greater biodiversity in ecosystems, species, and individuals leads to greater stability.
