Photosyntheis and resperationmove to bottom carbon dioxide is a product. a. carbon dioxide is a reactant. b. carried out in animals. c. carried out in plants. d. chemical reactionoxygen is a product. e. oxygen is reactant. produces usable energy source.

The correct answer is-

1. Photosynthesis- Carbon dioxide is a reactant, Oxygen is a product,  Carried out in plants, Produces usable energy source.

2. Respiration- Carbon dioxide is a product, Oxygen is reactant, Carried out in animals, Produces usable energy source.

Explanation:

Photosynthesis is a complex process which takes place in the green plants which synthesize the energy molecule called glucose. The reaction takes place in the presence of sunlight combining the carbon dioxide and water forming the glucose and oxygen gas.

Respiration is a complex process which involves the breakdown of the glucose molecule in the presence of oxygen and forming the energy molecule called ATP which is utilized in the metabolic reactions. The complex process releases carbon dioxide.
