Answer:
the bottom left one is the one
Answer:
The correct answer is - B. lower environmental availability of CO2
Explanation:
In C4 plants they have developed a mechanism for the CO2 concentrating and leads to the lower environmental availability of CO2 for these plants, C4 to avoid photorespiration.
These plants tend to be found in drier environments with high sunlight levels and not thrive in a cool shady forest due to this mechanism that results in low availability of carbon dioxide.
The given statement is False. Hence, the correct choice is F.
The activity of the plants and the animals are influenced by the abiotic factors present in their environment. The change in the abiotic factors outside the body such as the temperature, air and the presence of the water molecules provoke responses in the body of the organism. For example, the winters (low temperature) causes the loss of the leaves in the deciduous trees and the increase in the temperature causes more sweating in our body.
