Biodiversity
has 3 levels
variation in ecosystems or habitats
the number of species and their relative abundance
genetic variation within each species
species
a group of similar organisms with the same morphological, physiological,
ecosystem
it is a self sustaining unit
self contained/ defines area
community of organisms
many interactions occur between biotic and abiotic factors
all linked but food webs, energy flow in system, nutrient cycling
there is independence between organism and environment
niche
role of organism or how it fits in an ecosystem
including where it lives
how it obtains its energy
members of the same species occupy same niche
different species alter their use of the niche to avoid competition by dividing resources (Resource partitioning)
