ecology Flashcards
– group of similar organisms that breed and
produce fertile offspring
species
group of individuals that belong to the same species and live in the same area
population
different populations living together in a defined area
Community
all the organisms that live in a place
together with their physical environment
Ecosystem
– group of ecosystems that share similar climates
and typical organisms
Biome
– all life on Earth and all parts of Earth in
which life exists
Biosphere
organisms that capture
energy from sunlight or chemicals and convert it into
forms living cells can use
Producers (Autotrophs)
can not make their own
food; acquire energy from other organisms by ingesting
them
Heterotrophs consumers
heterotrophs that eat plants
herbivores
heterotrophs that kill and eat other animals
carnivores
heterotrophs whose diets include both plant and animal matter
omnivores
heterotrophs, who feed on detritus (small pieces of decaying
matter) by grinding them into smaller pieces (earthworms and
snails)
Detritivores
They chemically break down
organic matter (bacteria and fungi
Saprotrophs
an increase in the
concentration of a substance as you
move up the food chain
Bioamplification
It occurs within an
organism, where a concentration of a
substance builds up in the tissues and
is absorbed faster than it is removed
bioaccumulation
