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.
Which ecosystem is most stable and why describe?
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.
What makes for a healthy and stable ecosystem?
To be healthy and sustainable an ecosystem should maintain its metabolic activity level and its internal structure and organization and resist external stresses (Costanza, 1992).
What ecosystem is most likely to be 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.
Why are ecosystems stable?
All ecosystems are stable systems. This means that they maintain a natural balance. An ecosystem involves the flows of nutrients and energy (in the form of food). If the organisms Having in an ecosystem use up nutrients, like nitrogen, from their environment, without replenishing them, soon the system will collapse.
Which of the following are factors in determining 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)
Can we say that a balanced ecosystem is the same as a stable ecosystem?
When something is in equilibrium, it’s in balance. In the real world of ecosystems, nothing is ever perfectly balanced. So an ecosystem in equilibrium is said to be in a relatively stable state. This means that the populations of various animals in the ecosystem are generally staying within a similar range.
What is ecosystem stability in biology?
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.
How do you maintain an ecosystem?
Ten Simple Things You Can Do to Help Protect the Earth
- Reduce, reuse, and recycle. Cut down on what you throw away. …
- Volunteer. Volunteer for cleanups in your community. …
- Educate. …
- Conserve water. …
- Choose sustainable. …
- Shop wisely. …
- Use long-lasting light bulbs. …
- Plant a tree.
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.
Why does a complex ecosystem provide stability?
The reason greater stability is found in complex ecosystems is that with more complex interactions, the ability of organisms to deal with disturbances increases. … A food web depicts various ways in which organisms eat other organisms and obtain energy for their survival.
How do species impact the stability of an ecosystem?
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 is homeostasis in ecosystem?
– Homeostasis in ecology is the ability of an ecosystem to maintain its overall stability despite any disturbances. It is a result of the combination of biodiversity and the ecological interactions that occur between the species. – The ecosystem is maintained as an equilibrium.
