Answer 1

Answer:

Photosynthesis produces: glucose and $O_{2}$

                 ...from  $CO_{2}$, energy (light) and $H_{2} O$

Respiration produces: energy (ATP),$CO_{2}, H_{2} O$  

                ....from glucose and  $O_{2}$

Explanation:

These end products, namely $O_{2}$ and glucose are then used in respiration...

Using energy in the form of solar energy, plants, phytoplankton, algae, and other microorganisms produce chemical energy via photosynthesis. This complex mechanism is central to these species.

They combine light energy from the sun, water, and carbon dioxide.

6$CO_{2}$ + 6$H_{2} O$ + (energy) →$C_{6} H_{12} O_{6}$ + 6$O_{2}$

In the mechanism of cellular respiration, organisms extract energy from food. Sugars in the form of glucose are broken down into carbon dioxide and water during aerobic respiration in mitochondria to produce energy in the form of ATP (adenosine triphosphate).

$C_{6} H_{12} O_{6} + 6 O_{2} _{\to$ $6CO_{2} + H_{2} O + energy (ATP)$

The waste products, $CO_{2}$ and $H_{2} O$,  result from respiration, these are used as reactants in the photosynthetic process. In turn, its products are the reactants $O_{2}$  and $C_{6} H_{12} O_{6}$ in respiration.
