Ecosystem : biological communities with abiotic factors that affect it
Biome : large group of ecosystems
Habitat : area where an organism lives
Niche : organisms role in its environment
Predation : act of an organism consuming another
Symbiosis : interaction of 2 different species
Mutualism : interaction when both species are benefited
Commensalism : interaction between 2 species when one is not affected while the other is benefited
Parasitism : when one species is harmed while the other Is benefited

Matter : anything that has matter and takes up space
Nutrient : chemical substance an organism must obtain to sustain life
Nitrogen Fixation : conversion of nitrogen into a form usable by plants
Dentrification : converting fixed nitrogen back into a gas through soil
Limiting Factor : a biotic or aboitic factor that restricts natures tendencies
