ecosystems
a complex system of living organisms and their non-living environment

can sustain itself
consumer/heterotroph

absorbs the nutrients and also releases it into the ground
plants and algae needs said nutrients to grow
photosynthesis
a process that green plants convert the sun’s solar energy into glucose/carbohydrates
primary consumer
- relies on producers/autotrophs for energy
- includes herbivores
secondary consumer

includes omnivores and carnivores
population
an ecosystem made up of the same species
biomass
the mass of dry matter contained in a group of living things
detritus
