During the winter time, the total number of hours of sunlight decreases. what effect would this have on the process of photosynthesis?
a) the rate of photosynthesis would decrease and less glucose would be produced.
b) the rate of photosynthesis would increase and more glucose would be produced.
c) the amount of available sunlight does not influence the rate of photosynthesis.
d) it would have no effect on plants having needles instead of leaves, that stay green all year long.

A) The rate of photosynthesis would decrease and less glucose would be produced.

Explanation: Photosynthesis is a phenomenon in which green plants containing chlorophyll use sunlight as a source of energy to convert carbon dioxide and water to form glucose and oxygen.

Photosynthesis is the process used by plants, algae and certain bacteria to convert energy from sunlight and turn it into chemical energy in the form of glucose which is used a s a source of energy by many organisms.

Thus decreasing the amount of sunlight would decrease the rate of photosynthesis and less glucose will be produced.

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
