Answer: The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature.
Explanation:
They're considered to be human like hands. They have a thumb like humans which allows them to grip onto trees and maneuver better. It also helps them with their grip onto branches and trees because they rarely come down from up there, so they need to be able to grip tightly even a sleep. I would say it's natural selection due to evolution.
That answer would be false
Oxygen production of plants different at different times of the day due to presence of sunlight.
In cellular respiration, oxygen is taken in and carbondioxide is releases in the environment whereas in photosynthesis, carbondioxide is taken inside and oxygen is releases in the atmosphere so in this way matter is conserved during the processes of photosynthesis and cellular respiration.
Oxygen production of plants different at different times of the day because oxygen only produced when there is photosynthesis process which only occurs in the presence of sunlight. If plant was placed in a completely dark environment then there is no oxygen is produced and no photosynthesis occur.

Hummingbirds pollinate native cactus. In areas of the Sonoran Desert with few hummingbirds, (5)invasive species such as buffelgrass have taken over the ecosystem. The theory that the balance of ecosystems can rely on one keystone species was first established in 1969 by American zoology professor Robert T. Paine.
