Limiting Factors

• Water depends on the rainfall and location.
• Sunlight depends on climate, season and surroundings (tall trees covering short plants).
• CO2 is used by all plants.
• A limiting factor is an environmental factor that limits growth or activities of a living organisms. They can be biotic or abiotic.
• Some biotic factors are food and predators.
• Some abiotic factors are CO2, sunlight and water.
• Wavelength is a limiting factor.
• Sunlight is white light, so it has all the visible wavelengths, but growing plants indoors is not the same.
• Water is a limiting factor.
• Water is one of the raw materials of photosynthesis, water shortage can slow and even stop the process of photosynthesis.
• Less water, less splitting electrons, and less photosynthesis.
• Light Intensity and CO2 are limiting factors.
• Increasing light or CO2 increases photosynthesis to a point.
• Temperature is a limiting factor.
• Increasing temperature, increases photosynthesis, until it reaches optimal temperature. Afterwards, the rate of photosynthesis decreases.
• Any chemical reactions uses enzymes.
• Denatured enzymes are irreversible.
