what is the relationship between ecological succession and equilibrium in an ecosystem?
320743
Equilibrium in ecology refers to a state that occurs such that a small disturbance or change is counter balanced by another change so that the community is restored to its original state. Thus, as a community goes through multiple changes through each stage of succession, it is not in equilibrium.

Biotic and Abiotic Factors An ecosystem is defined as any community of living and non-living things that work together. ... Both biotic and abiotic factors are related to each other in an ecosystem, and if one factor is changed or removed, it can affect the entire ecosystem.

An ecosystem is the term used to describe both the biotic (living) and abiotic (nonliving) factors in a system. ... A biosphere is the term used to describe the combination of every ecosystem on the planet.

Which of the following best describes the link between survivorship curves and equilibrium species? Equilibrium species are limited by density-dependent factors and have few offspring. Opportunistic species are limited by density-independent factors and have many offspring.

Populations and succession. A population is a group of organisms of the same species occupying a particular space at a particular time that can potentially interbreed. In any ecosystem relationships are dynamic, usually moving from colonisation (pioneer) to climax communities in a process known as succession.

Ecology and evolution are intimately related because an organism's ecological situation directs its evolution, and the organism's response to its ecological situation may be evolutionarily. ... In a general sense, ecological situations can be viewed as forces leading to evolutionary solutions to ecological problems.

An ecosystem is a community of living organisms interacting with one another and their non-living environment within a particular area. The biosphere is that part of the earth inhabited by living organisms, including land, ocean and the atmosphere in which life can exist.

Key points. Ecology is the study of how organisms interact with one another and with their physical environment. The distribution and abundance of organisms on Earth is shaped by both biotic, living-organism-related, and abiotic, nonliving or physical, factors.

Succession. ... In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area that was previously occupied by living things is disturbed, then re-colonized following the disturbance.
250461
The primary succession occurs following an opening of a pristine habitat, e.g., on lava flow, an area left from retreated glacier, or abandoned mine. The secondary succession is a response to a disturbance e.g., forest fire, tsunami, flood, etc.

A population is a group of individuals of the same species. A community is a group of populations. An ecosystem is a community combined with the abiotic (non-living; think nutrients, precipitation, disturbances) factors that influence the abundance and distribution of those populations.

Biodiversity provide stability to the ecosystem and maintains the ecological balance. Plants and animals in ecosystem are linked to each other through food chain and food web. The loss of one species in the ecosystem affects the survival of other species. Thus the ecosystem becomes fragile.

An ecosystem consists of living and nonliving things in an area. A community is all the populations in that area. ... A population is made up of only one species.

Ecological imbalance is when a natural- or human-caused disturbance disrupts the natural balance of an ecosystem. The balance of an ecosystem can be disrupted by natural or human-caused disturbances. If a species disappears or a new species is introduced it can shift an ecosystem to a state of ecological imbalance.

It has been shown that biodiversity of an area has a large impact on the ecosystem stability of that area. ... This increase in complexity makes it more likely that the ecosystem will return to a stable state after a disturbance, because the ecosystem has more ways to respond to a disturbance and fix problems.

An ecosystem describes all the living organisms (biotic components) with their physical surroundings (abiotic components) in a given area. A community describes only the living organisms and their interactions with each other.

An ecosystem is a discrete structural, functional and life sustaining environmental system. ... Biotic component of the ecosystem includes the living organisms; plants, animals and microbes whereas the abiotic component includes inorganic matter and energy.
