Question

variation optimal and limiting factors on light and temperature​

Answer 1

Answer:

Definition of limiting factor and law of limiting factors. ... For example, photosynthesis is affected by many factors, such as light, temperature, and carbon dioxide concentration, but on a warm sunny day carbon dioxide concentration will be the limiting factor as light and temperature will be at optimum levels.

Answer 2

Answer:

Temperature, carbon dioxide content, and light intensity are the key variables influencing photosynthetic rate. Any one of these could, under a certain circumstance, turn into a limiting factor, which would then obscure the impacts of the other components while directly affecting the rate at which photosynthesis can occur.

Explanation:

• At low light levels, the rate of the light-dependent response and hence photosynthesis normally rises proportionately as light intensity increases.
• However, as light intensity rises higher, another component ultimately caps the rate of photosynthesis. the rate reaches a plateau. Chlorophyll may be degraded at very high light intensities, and the rate rapidly declines.
• The photosynthetic reactions that don't require light are temperature-dependent.
• They are enzyme-catalyzed reactions.
• The overall rate rises as the enzymes get closer to their ideal temperatures.
• For every 10 °C increase in temperature, it roughly doubles.
• As enzymes are denatured above the optimal temperature, the rate starts to drop until it eventually stops.
