Describe photosynthetic organisms as the primary producers of food and biomass in ecological systems.
Describe photosynthesis in plants and algae as an endothermic chemical reaction that utilises light energy to convert carbon dioxide and water into glucose and oxygen.
Explain how environmental conditions, specifically temperature, light intensity, and carbon dioxide concentration, act as limiting factors on the rate of photosynthesis.
Explain the complex, simultaneous interactions of multiple limiting factors on the overall rate of photosynthesis.
Investigate the physiological effect of varying light intensities on the rate of photosynthesis through practical experimentation.
Explain the mathematical relationship between the rate of photosynthesis and light intensity, particularly its inverse proportionality to the distance from a light source.
Calculate expected light intensities and photosynthetic rates using the inverse square law.
