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.

Kobotan [32]

Parietal cells produce gastric acid (hydrochloric acid) in response to histamine (via H2 receptors), acetylcholine (M3 receptors) and gastrin (gastrin receptors). Parietal cells contain an extensive secretory network (called canaliculi) from which the HCl is secreted by active transport into the stomach.

How is the process of natural selection involved in evolution?
Ann [662]
Natural selection means that the organisms better adapted to their environment, that is, they have developed the right characteristics/skills/response to the external ambient, have higher chance to survive, making the next generations genetically inherit such acquired surviving characteristics.
These generations will thus have a higher chance of survival, making these species being "naturally selected" as survivors, while those who haven't or are slower in this process, have a higher risk of elimination.
