What is happening in step
1?

• Animals are decomposing and realizing carbon into the soil.
• Animals are releasing energy into the environment and storing carbon.
• Animals are turning carbon dioxide from the atmosphere into organic molecules.
• Animals are breaking down organic molecules and releasing carbon dioxide into the atmosphere.

Why is sunlight important for the survival of living organisms?

• Sunlight creates fertile soil, which allows plants to release energy to other organisms.
• Sunlight allows decomposers to break down dead organisms, which plants and animals use as energy for photosynthesis.
• Sunlight is needed for plants to produce food, and the energy is then passed to other organisms through food consumption.
• Sunlight increases the amount of oxygen in the air, which is then converted to the carbon dioxide necessary for photosynthesis.
