Vocab/Info of Ecosystem Structure Flashcards
population
a group of like species that live in the same habitat
community
a collection of all living organisms in every trophic level who live in the same habitat
ecosystem
includes all living organisms in a habitat and the land, water and air resources that make up their environment
ecological niche
the combination of all behaviors that an organism uses to decrease competition and increase access to resources, leading to its survival
resource partitioning
when species feed in a separate territory or region to avoid competition
range of tolerance
represents the gap of acceptable conditions the species will feed, live, migrate to
keystone species
very important, extinction would lead to extinction of many other species
edge effects
a change in species composition, physical conditions, or other ecological factors at the boundary between two ecosystems
genetic biodiversity
a variety of DNA alleles or variations within a population
ecosystem biodiversity
a variety of microecosystems or habitats for organisms to
occupy- more opportunity for specialization and resource partitioning
species biodiversity
a community has a large variety of different species- creating more complex and healthy food webs and species interactions
