The ultimate source of energy in an ecosystem is either light energy from the sun or chemical energy from compounds originating deep within Earth.
Autotrophs (or producers) make their own food using light energy or chemical energy while heterotrophs (or consumers) use other organisms as a source of food.
The organisms within an ecosystem are related by their energy roles, and an ecosystem can be divided into trophic levels to express these roles.
An ecological pyramid illustrates the change in energy or biomass at different trophic levels within an ecosystem.
Each organism occupies a unique niche in an ecosystem.
As a result of competition for limited resources, two different species cannot occupy the same niche, because one species will be more successful than the other and will cause the other to die off or leave the ecosystem.
When organisms of different species interact with one another in an ecosystem, they do so in three basic ways: predation, herbivory, or symbiosis.
Ecosystems tend toward stability when there are regular population cycles between predators and their prey and when the population number of the keystone species is at a healthy …show more content…
