Some environmental oxygen also enters through stomata for respiration (the breakdown of stored sugar for energy). 9. Carbon dioxide enters the plant through these openings for photosynthesis and waste oxygen exits through these same openings. Light intensity required to open the stomata is very low, as compared to the intensity required for photosynthesis. Biotic factors are the living or once-living organisms in the ecosystem.When we say living organisms, they are capable of growth, reproduction, they eat, they breathe, and have the characteristics of living organisms.
