Define biotic factor
All the biological components of an ecosystem (inter/intraspecific competition, predation, disease, food supply).

Define abiotic factor
All the non-biological compenents of an ecosystem (pH, soil type, CO2/O2/N2/H2O concentration/availibility).

Define producer
Autotrophic organisms that convert light energy into chemical energy, that can then be availible to consumers.
5 of 9
Define consumer
Organism that eats other living organisms.
6 of 9
Define decomposer
