Answer:
The correct answer will be option-A.
Explanation:
Photosynthesis is a process which uses sunlight energy to synthesize food in the form of glucose. The process takes place in the chloroplast in two stages: light-dependent reactions and light-independent reactions.
The light-independent reaction produces to convert the carbon dioxide from the atmosphere to glucose through the Calvin cycle. The carbon gets fixed and reduced form+4 state to +1 state.
Respiration is the process which oxidizes the glucose molecule to produce energy in the form of ATP molecules. This ATP is utilized by the cell to perform various functions.
Thus, option-A is the correct answer.

Answer: Gene Pool
Explanation:
Gene pool is the collection of all the gene and various allelic form of those gene within a population.
Variation naturally occurs among the gene of members of the same species that interbreed. 
Gene pool It is therefore the total number of gene of all the members among the population of a particular species. Gene pool is used to determine the level of mutation, variation, genetic diversity among members of a population.
