what are three requirements for a stable ecosystem?

It is self-supporting because the requirements for a stable ecosystem are present: ENERGY (1) is supplied to the ecosystem by light. There are PLANTS (2) to change the light energy into the organic molecule of energy (glucose). RECYCLING (3) of materials occurs during photosynthesis and respiration.

1. A stable society should be self sustaining. 2. It should have social institutions such as educational institutes, political institutes, religious institutes, etc.

It is useful to categorize the requirements for life on Earth as four items: energy, carbon, liquid water, and various other elements. These are listed in Table 1 along with the occurrence of these factors in the Solar System (2).

The ability to maintain ecological processes over long periods of time. Sustainability of an ecosystem is the ability of that ecosystem to maintain its structure and function over time in the face of external stress. SPEAKER'S NOTES: Sustainability is the ability to maintain something over a long period of time.

Requirements of a Control System. Stability, accuracy and speed of response are the three requirement s of a control system. Stability: A system is to be stable if the output of the system after fluctions, variation or oscillation, if any, settles at a reasonable value for any change in input or change in disturbance.

It must be stable. It must be capable of being expressed when needed. It must be capable of accurate replication. It must be transmitted from parent to progeny without change.

Generally speaking, greater species diversity (alpha diversity) leads to greater ecosystem stability. This is termed the "diversity–stability hypothesis." 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.

Healthy ecosystems clean our water, purify our air, maintain our soil, regulate the climate, recycle nutrients and provide us with food. ... Biodiversity is the key indicator of the health of an ecosystem. A wide variety of species will cope better with threats than a limited number of them in large populations.

Requirements for growth Plants need air, light, warmth, water and nutrients to be healthy. If a plant doesn't have one of these requirements it could affect its growth or even die.

A sustainable development model (SDM) framework that is inclusive of the “whole” natural environment is presented to illustrate the integration of the sustainable development of the “whole” ecosystem. The ecosystem approach is an inclusive framework that covers the natural environment relevant futures and constraints.

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.
