Answer: Abiotic factors are the non-living parts of the environment that can often have a major influence on living organisms. Abiotic factors include water, sunlight, oxygen, soil and temperature. ... Without water, animals become weak and confused, and they can die if they do not rehydrate. The biotic factors in an ecosystem are the living organisms, such as animals. These living organisms affect each other and influence the health of the ecosystem. The carrying capacity depends on biotic and abiotic factors. If these factors improve, the carrying capacity increases. Abiotic factors may include space, water, and climate. The carrying capacity of an environment is reached when the number of births equal the number of deaths. A limiting factor determines the carrying capacity for a species.
