Which of the following abiotic factors might have an effect on how much photosynthesis can occur by the producers in an ecosyste
Evgesh-ka [11]

Abiotic factors such as temperature, water quality, air quality, soil quality, and sunlight efficiency affect the rate of photosynthesis. Thus, the correct option is D, i.e. All of the above can affect photosynthesis.

<h3>What is Photosynthesis?</h3>

Photosynthesis may be defined as a process through which green plants synthesized their own food (glucose) via carbon dioxide and water in the presence of sunlight.

The rate of photosynthesis primarily depends on the numerous abiotic factors which are present in a particular environment.

For example, Desert plants accomplish photosynthesis by the CAM pathway, which requires less water as compared to rainforest plants.

The maximum rate of photosynthesis occurs in the region of photosynthetically active radiation (PAR), which belongs to the wavelength of 400nm-700nm.

Therefore, it is well described above.
