Here's why:
* Plants are living organisms: They grow, reproduce, and require energy to survive.
* Photosynthesis: Plants use a process called photosynthesis, where they take in carbon dioxide (CO2) and water (H2O) and, using sunlight as energy, produce glucose (sugar) for their own use and release oxygen (O2) as a byproduct.
* Oxygen for Animals: Animals, including humans, breathe in oxygen and exhale carbon dioxide. This oxygen is crucial for their survival and energy production.
Therefore, plants play a vital role in the ecosystem by producing the oxygen that animals need to breathe.
