SUNLIGHT
Mazyrski [523]

Answer:

"without light energy from the sun, photosynthesis would still occur" is completely false. Light energy is needed for the light-dependent reactions, or simply the light reactions, of photosynthesis.

"oxygen is an input into photosynthesis, carbon dioxide is an output" is also completely false. It is the opposite.

These statements are true, however:

SUNLIGHT

CARBON DIOXIDE

WATER

MINERALS

OXYGEN

PLANT SUGARS

Carbon dioxide enters the leaves through stomata (tiny holes) in the leaves.

Sunlight is an input, CO2 is an input, water is an input (taken in through the roots, transported through the veins), minerals are a collective input, oxygen is an output (produced during photolysis), and plant sugars are an output (glucose, for an example).
