What makes one ecosystem strong and another weak?

Biodiversity can explain why one ecosystem is strong and another weak in the face of change. The more intertwined and connected species, genetic, and ecosystem diversity is, the stronger and more resilient an ecosystem is. A species with little variation is more susceptible to be greatly impacted by change.

What makes one ecosystem strong and another one weak?

Terms in this set (67) What makes an ecosystem strong and another ecosystem weak in the face of change? … The volume of species, their genetic diversity, and the complexity of the ecosystem form such rich biodiversity in the forest that one species gap won’t cause the system to collapse.

What makes one ecosystem stronger than the other?

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 can make an ecosystem unstable?

1 Answer

  • Removal of native species.
  • Introduction of new species.
  • Pollution, toxification of an area.

What two things make an ecosystem stable?

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.

What makes an ecosystem strong?

A healthy ecosystem consists of native plant and animal populations interacting in balance with each other and nonliving things (for example, water and rocks). Healthy ecosystems have an energy source, usually the sun. … Decomposers break down dead plants and animals, returning vital nutrients to the soil.

How is Shannon diversity calculated?

How to calculate the Shannon diversity index? Calculate the proportion (pi) of each species – divide the number of individuals in a species by the total number of individuals in the community. For each species, multiply the proportion by the logarithm of the proportion. Sum all the numbers from step 2.

What makes an ecosystem with 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.

What is stability in an 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 are the limiting factors that help balance the ecosystem?

Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources. Others are abiotic, like space, temperature, altitude, and amount of sunlight available in an environment. Limiting factors are usually expressed as a lack of a particular resource.

What factors affect ecosystems?

They include factors such as light, radiation, temperature, water, chemicals, gases, wind and soil. In some environments, such as marine environments, pressure and sound can be important abiotic components.

What are the factors affecting ecosystem degradation and loss?

Important direct drivers include habitat change, climate change, invasive species, overexploitation, and pollution. Most of the direct drivers of degradation in ecosystems and biodiversity currently remain constant or are growing in intensity in most ecosystems (see Figure 4.3).

What can destroy ecosystem?

Various human activities threaten to disrupt this balance and destroy the world’s ecosystems.

  • Pollution. Pollution is one of the main causes of ecosystem destruction. …
  • Climate Change. …
  • Land Clearing. …
  • Resource Exploitation. …
  • Population Decline.

What makes an ecosystem resilient?

An ecosystem can display resilience in at least two ways: in the ability to resist an environmental perturbation and not switch to another state, and in how quickly it recovers after the disturbance (1).

Which 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.

How does the stability of an ecosystem depend on?

Stability of ecosystem depends upon the interchange between producers and consumers. Their interaction leads to formation of trophic levels and energy flow in an ecosystem. Trophic levels are steps or divisions of food chain characterized by specific method of obtaining food.
