Explanation:
An environment's biology includes both abiotic factors like atmosphere, water, soil, sunlight and temperature; and biotic factors which are living components of the ecosystem.
These factors lead to a gradual change of an ecosystem over time; however, humans drastically impact the environment through over-exploitation and pollution- we disrupt normal abiotic and biotic interactions.
Oxygen is an inorganic gas that makes up the atmosphere, thus it is abiotic
; it is utilized by animals which undergo cellular respiration to produce energy for life processes. A field mouse may continue to reproduce, increasing the population, and feed on other biotic factors, and aid in nutrient cycling.
