Question

What is a waste product created by plants during the light-dependent reaction of photosynthesis that is released as a gas into the atmosphere and used by heterotrophs.

Answer 1

Oxygen

Step-by-step explanation:

Oxygen is a gaseous non-metal element that is taken up by animals (heterotrophs) during the process of respiration. Animals need oxygen to be able to survive.

Oxygen is produced by plants (autotrophs) into the atmosphere through a process called photosynthesis. The process of photosynthesis is when plants take up carbondioxide and water in the presence of energy captured from sunlight and further produces glucose (carbohydrate) and release oxygen into the atmosphere as a byproduct.
