Ecology
The study of interactions that take place between organisms and their
environment.
Interdependence
all species rely on other species for survival
Organism
An individual living thing
Population
A group of organisms, all of the same species, that live in the same place at the same time.
Biomass Pyramid
shows the total mass of organisms in each level of a food chain
Number Pyramid
shows the number of organisms in each level of a food chain
Community
All the populations of different species that live in the same place, same time
Energy Pyramid
shows the available energy in each level of a food chain
Niche
an organism's role in the ecosystem
Ecosystem
All populations in an area and the abiotic factors they can interact with
Food pyramid
a diagram that shows the relative amount of energy, organisms, or biomass in each trophic level
Biosphere
The portion of Earth that supports life
Habitat
place a plant or animal lives
Transpiration
the release of water vapor directly into the air from an organism
Detrivore (Detritivore)
organism that eats decaying organisms
Biotic factors
all the living organisms that inhabit an environment
Abiotic factors
the nonliving parts of an organism's environment.
Omnivore
organism that eats plants and animals
Carnivore
organism that eats animals only
Acclimation
when some organisms migrate or go dormant to deal with unfavorable abiotic factors
Herbivore
organism that eats plants only
Producer
- organisms that can make their own energy by doing photosynthesis
Secondary Consumer
consumer that eats a consumer
Consumer
organisms that cannot make their own energy and must eat others
Primary Consumer
consumer that eats a producer
Food chain
shows the direct path of energy from a producer to a consumer in an ecosystem
Heterotroph
organism that cannot make their own food
Trophic Level
an organism's position in a food chain or food pyramid
Food Webs
show all the interconnected food chains within an ecosystem
Autotroph
organism that can create its own food
Photosynthesis
the chemical reaction where water & carbon dioxide combine to form glucose
Respiration
the chemical reaction that releases the energy in glucose
