Choose the correct statement.

There is linear relationship between incident light and CO₂ fixation rates at low light intensities.

At higher light intensities the rate of photosynthesis does not show further increase because other factors become limiting.

Light saturation for photosynthesis occurs at 10% of the full sunlight.

Light becomes a limiting factor for plants growing in shades or in shades of other plants of dense forests and during cloudy days.
