I will be able to investigate how organisms and populations in an ecosystem depend on and may compete for biotic and abiotic factors: quantity of light, water, range of temperatures, and soil composition.
Organism: a living thing
Population: The same kind of organisms that live in the same area during the same time.
Biotic: living thing(s)
Biotic: Dog
