look, a flower! You know, plants provide the oxygen that animals need to survive. Also, plants and animals provide the water, carbon dioxide, and ATP energy that plants need to survive.
A process called photosynthesis occurs when the reactants of photosynthesis, carbon dioxide, water, and light energy help to make photosynthesis occur. The products of photosynthesis are glucose and oxygen. Photosynthesis only occurs in plants during day.
A process called cellular respiration occurs when reactants of cellular respiration, oxygen and glucose help to make cellular respiration occur. Products of cellular respiration are ATP energy, carbon dioxide, and water. Cellular respiration occurs both day and night in plants and animals.
This process occurs over and over again in a continuous loop called the energy cycle.
Plants depend on animals for survival and animals depend on plants for survival.
