What is a true statement about ecosystems?

What is a true statement about ecosystems?

True – Ecosystems are dynamic and a greater input leads to a greater biodiversity.

What are three 3 key features of a healthy ecosystem?

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

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

What kind of ecosystem is healthy one?

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.

Which statements describe ecosystems biodiversity is one way to judge the health of an ecosystem ecosystems must be balanced to survive a healthy ecosystem can support an unlimited number of life forms the parts of an ecosystem exist independently and have little to do with each other people’s activities?

Thus, the correct statements would be: Balance is required for the survival of an ecosystem. People’s actions sometimes improve the health of an ecosystem. One way to determine an ecosystem’s health is by its biodiversity.

How do you keep a healthy ecosystem?

How to maintain a balanced ecosystem

  1. Manage Natural Resources Carefully. A concerted effort to use natural resources in a sustainable manner will help to protect and maintain ecological balance.
  2. PROTECT THE WATER.
  3. reduce logging.
  4. reduce chlorofluorocarbon.
  5. Stop open burning.

What is the most harmful thing to environment?

How do you balance an ecosystem?

You have the power to have a positive effect, no matter how small, in maintaining the delicate balance of the Earth’s ecosystem. Recycle to help prevent the over-harvesting of natural resources. Conserve energy by choosing more energy efficient appliances and automobiles.

What is a balanced ecosystem called?

Ecological balance is a term describing how ecosystems are organized in a state of stability where species coexist with other species and with their environment. These ecological changes are called disturbances. A disturbance is any change that causes a disruption in the balance of an ecosystem.

How do animals keep the ecosystem balanced?

The Balancing Act Each animal plays a role to help keep the balance in nature. Animals that feed primarily on plants bring about a balance in the plant world. But, we should remember that they help to remove the bodies and carcasses of other animals that have died. This helps in keeping the natural habitat healthy.

What makes a 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. Resilience is the speed at which an ecosystem recovers from a disturbance. First is to maintain a diversity of plants and animals in an ecosystem.

What is an example of a stable ecosystem?

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. Their volume is massive and thus, minor shifts in oceans are not easily felt.

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 are three requirements for a stable ecosystem?

Stability of an ecosystem also needs to have a resistance to change. This resistance to change has three forms: Inertia – the resistance to change, Resilience – the ability to recover from change and succession – the replacement of species by another. Individuals are born; they grow, and they die.

Why are diverse ecosystems more stable?

Increased alpha diversity (the number of species present) generally leads to greater stability, meaning 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.

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. Interactions within ecosystems are extremely important to their functioning.

Which factor is most important in predicting whether an ecosystem is stable?

Variation among species in their response to such fluctuation is an essential requirement for ecosystem stability, as is the presence of species that can compensate for the function of species that are lost.

Why it is important that a community is stable?

A stable community is one in which the size of the populations of all species remain relatively constant over time. In the example above the amount of grass, and the numbers of rabbits and foxes all remain relatively constant. The different populations are living in a healthy balance with their environment.

What are the factors that affect the stability of an ecosystem?

Factors affecting stability: Disturbance frequency and intensity (how often and what kind of tillage) Species diversity (intercropping or rotations), interactions (competition for water and nutrients from weed species), and life history strategies (do the species grow fast and produce many seeds or slow with few seeds)

Which ecosystem is most stable and why?

The ocean is the most stable ecosystem. It is stable due to its natural liquid nature (saline), dissolved oxygen, light and temperature.

Which ecosystem has the most stable conditions?

Oceans

Which is the largest and most stable ecosystem?

ocean

Which ecosystem has highest productivity?

Tropical rainforests

Why is productivity important to an ecosystem?

Ecosystems have characteristic amounts of biomass at each trophic level. The productivity of the primary producers is especially important in any ecosystem because these organisms bring energy to other living organisms by photoautotrophy or chemoautotrophy.

Which ecosystem has least productivity?

Tundra
