Do dead plants give off oxygen?

Answer 1

In short, no. The oxygen they produce is from photosynthesis, which in a dead tree will by definition not be happening. There will be many products produced from its decay, like CO2. The only metabolic process that produces oxygen is photosynthesis which only requires CO2, water and light, none of which will come from a dead tree.

Answer 2

No, dead plants do not give off oxygen because they are no longer undergoing photosynthesis, the process by which plants generate oxygen. Instead, dead plants undergo decomposition, releasing carbon dioxide back into the environment.

Answer 3

No, dead plants do not give off oxygen. Dead plants will release carbon back into the atmosphere.
