Sunlight and nutrient
availability are the factors influencing photosynthetic productivity. Plants,
fungi, and algae obtain the energy they need to live from photosynthesis. The
amount of sunlight and the amount of other nutrients (especially nitrogen, phosphorous
and iron) available influence the productivity of organisms through
photosynthesis.
Explanation:
Respiration is the process of releasing energy through the breakdown of nutrients such as glucose. Respiration can be aerobic (uses oxygen) or anaerobic (does not use oxygen). Aerobic respiration takes place continuously in both plants and animals. It occurs through a process known as cellular respiration.
