an ecological community consists of all the species that live and interact in a given area. however, different species can lives with various species, overlapping and underlying depending on the area. species are categorized based on energy source: autotrophs, heterotrophs. because as energy (biomass) passes through different levels, some energy is lost in different ways: most energy is held at the primary producersprimary consumerssecondary consumers, variations of biomass depends on community. Types of ecological interactions: predationoscillating effect (if there are more predators, extinction of prey might is common.
