Question

Which organisms release carbon dioxide as waste?

1-consumers only
2-consumers and decomposers
3-producers and decomposers
4-producers only

Answer 1

consumers and decomposers

(but plants also release co2 at night! )

Answer 2

The organisms that release carbon dioxide as waste are known as consumers and decomposers (option 2).

• Animals and humans that eat plants as a significant source of nutrients are referred to be consumers.

• They breathe aerobically, which means they take oxygen from the air and exhale carbon dioxide as a byproduct of respiration.
• Decomposers are creatures that eat dead and rotting plant and animal matter.
• They break down complex organic matter into simpler forms while emitting carbon dioxide as waste.
• Plants (producers) use carbon dioxide in their photosynthetic mechanism.

• Hence, carbon dioxide is given out by consumers and decomposers which is then used up by the producers.
