Use this life science worksheet to help students boost their understanding of photosynthesis and how matter and energy cycle on Earth. Designed for middle school learners, this worksheet begins with a diagram and a short passage explaining how photosynthesis works and how animals and photosynthetic organisms are connected. Students will then answer a series of comprehension questions about the inputs and outputs of photosynthesis, how animals depend on matter from plants for growth and survival, and why the sun is the ultimate source of energy on Earth.
