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.
What do stable ecosystems have?
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 is meant by 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.
Which one has more stable ecosystem?
Oceans are the most stable ecosystems. Other terrestrial ecosystems undergo changes and succession of biotic components. But oceans remain stable for the long duration of time.
Which of the following is true for the stabilized ecosystem?
Which of the following is TRUE for the stabilized ecosystem? Explanation: Ecosystem has been classified on the basis of community metabolism. The ratio of photosynthesis to respiration, i.e., P/R is equal to 1 for a stabilized ecosystem.
Which of the following is one of the principles of Ecosystem Stability?
The Principles of Ecosystem Stability are: Ecosystems dispose of waste and replenish nutrients by recycling all elements. Ecosystems use sunlight as their source of energy. The size of a consumer population is maintained such that overgrazing and other forms of overuse do not occur.
What characteristics contribute to the stability of a community?
The features of a stable community are as follows:
- (i) Communities should have greater biodiversity for greater stability.
- (ii) It should be able to prevent invasion by alien species.
- (iii) It should be able to restore itself in a short period of time.
- (iv) Variations should be minimal in the community.
Are ecosystems always 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.
What is a stable community in biology?
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.
How does an ecosystem maintain balance?
A balanced ecosystem works via energy and material cycling. The chief energy source of ecosystems is sunlight. Photosynthesis of sunlight by plants creates oxygen as a waste product, which in turn is used in respiration by animals. Animals, in turn, create carbon dioxide as waste, and that is used by plants.
On what does the stability of a natural ecosystem depend?
How does the stability of an ecosystem depend on its producers? They provide the basis for an ecosystem’s energy. What happens to energy as it flows through a food web? The energy is stored within an organism but most of the energy is lost to the environment as heat.
What is stability in biodiversity?
Biodiversity and Ecosystem Stability
Ecosystem stability is the ability of an ecosystem to maintain a steady state, even after a stress or disturbance has occurred.
Why are complex ecosystems more stable?
The reason greater stability is found in complex ecosystems is that with more complex interactions, the ability of organisms to deal with disturbances increases.
Why organism is important in maintaining the stability of ecosystem?
Living organisms change soil composition, chemical features, the composition of the atmosphere as well as the hydrosphere, oxygen-carbohydrate balance and, fmally, the structure and functions of the biosphere. They create the conditions necessary for life and ensure biosphere stability.
Which of the following is likely to contribute to the stability of an ecosystem?
The factors that stabilize the ecosystem are species diversity, nutrients, energy flow, population under control, distributions of plants and animals.
What ecosystem is the world largest and most stable ecosystem?
Of all the ecosystems, ocean is the largest and most stable ecosystem.
What is true about the ecosystem?
An ecosystem is the structural and functional unit of the biosphere comprising biotic and abiotic components. Organisms can be classified into three main categories – producers, consumers and decomposers. In a true ecosystem, producers outnumber consumers.
Which is not the characteristic of population?
Complete Answer:
The phenotype is not really a defining characteristic of the population. It is a collection of measurable characteristics of a person arising from the interaction of the genotype with the ecosystem. Population size is the correct figure of people in the general population.
What is the final stable community in an ecological succession called?
An ecological community in which populations of plants or animals remain stable and exist in balance with each other and their environment. A climax community is the final stage of succession, remaining relatively unchanged until destroyed by an event such as fire or human interference.
What is environmental stability?
Stability of environmental systems is essentially a concept that acknowledges, responds to change, or lacks change in the systems involved. Discussion must therefore incorporate ideas of equilibrium, and of how, or by what mechanism, an average condition or equilibrium is maintained (White et al., 1984, p.
Which causes the stabilization of the community?
Stabilizing causes. These include the climatic factors resulting in the stabilization of community. Primary succession is the process by which a single new community gets established in a bare area. The species is usually microbes which act as the pioneer species of the succession.
How many of the following are the characteristic feature of stable ecosystem?
Solution : The characteristics that make a community stable are <
br>
(i) Less variation in productivity from year to year. <
br>
(ii) Resistance or resilience to occasional disturbances (natural or man-made). <
br>
(iii) Resistance to invasions by alein species.
Which of the following is a feature of a stable community?
Solution : Features of stable community are as follows: <
br>
(i) Communities should have greater biodiversity for greater stability. <
br>
(ii) It should be able to prevent invasion by alien species. <
br>
(iii) It should be able to restore itself in a short period of time.
What is stable community Class 12?
A stable community is self-perpetuating and final biotic community that is in perfect harmony with the physical environment. It does not show much of changes i.e., less variation in year to year productivity and is usually resistant to natural or man made disturbances as well as alien invasion.
What is an example of a ecosystem?
Examples of ecosystems are: agroecosystem, aquatic ecosystem, coral reef, desert, forest, human ecosystem, littoral zone, marine ecosystem, prairie, rainforest, savanna, steppe, taiga, tundra, urban ecosystem and others.
