Roles in an Ecosystem-(First Level consumers)
are consumers that get their energy from producers first level consumers are usually herbivores or omnivores. (Second Level consumers
) are consumers that get their energy from first level consumers. Second level consumers are usually omnivores or carnivores.
(Third Level consumer
) are consumers that get their energy from second level consumers. Third level consumers are usually carnivores.
Species Interactions- within ecological webs include four main types of two-way interactions: mutualism, commensalism, competition, and predation (which includes herbivory and parasitism), because of the many linkages among species within a food web, changes to one species can have far-reaching effect.
Community structure- is the ecologist's term for indicating what organisms are present in a given environment, in what numbers, and how they relate to each other,traditionally, a biological community is named for a dominant element.
Ecological Succession- is the gradual process by which ecosystems change and develop over time. Nothing remains the same and habitats are constantly changing. There are two main types of succession, primary and secondary.
