∞ • Plants and animals are linked for survival through the carbon dioxide-oxygen cycle.
Photosynthesis • To undergo photosynthesis, plants need: • sunlight • water • carbon dioxide Carbon Dioxide
Photosynthesis • Plants make food and oxygen in the process of photosynthesis. • Plants release the oxygen into the air. Oxygen Food
Carbon dioxide • Carbon dioxide is found in the air. • It gets there from: • volcanoes erupting • burning fossil fuels • animals
Animals • Plants make food through a process called photosynthesis • When animals consume the plants, they are consuming energy from the plants. • Animals convert the plant’s energy into the energy they need to grow and thrive.
