levels of organization
organism-> population-> community-> ecosystem-> biosphere
organism

community
all populations of different species that live in the same area
ecosystem
communities and abiotic factors that are in an environment
biosphere

producers
autotrophs convert light energy into glucose through photosynthesis
*ALL ENERGY ON EARTH ORIGINATES FROM THE SUN
ecology
the study of the environment as the home to living things
consumers
heterotrophs obtain energy by eating glucose
Herbivore
organism that only eats plants known as primary consumers
carnivore
