1. Plants capture sunlight: Plants have a green pigment called chlorophyll that absorbs sunlight energy.
2. Plants take in carbon dioxide: Plants absorb carbon dioxide from the air through tiny pores on their leaves called stomata.
3. Plants take in water: Plants absorb water from the soil through their roots.
4. Photosynthesis occurs: Using the energy from sunlight, plants combine carbon dioxide and water to create glucose (a type of sugar) and oxygen. This process happens in the chloroplasts of plant cells.
5. Plants release oxygen: Plants release the oxygen produced during photosynthesis back into the atmosphere.
6. Plants store energy: The glucose produced during photosynthesis is the plant's source of energy, and it's also stored in the plant's tissues (roots, stems, leaves, etc.).
7. Animals eat plants: When animals eat plants, they consume the stored glucose (and other nutrients), which provides them with the energy and building blocks they need to survive.
In summary, plants use photosynthesis to create food (glucose) for themselves and other organisms. This process is essential for life on Earth as it provides the foundation for the entire food chain.
