Introduction: Ecological Cycles Allow Matter To Be Passed From One Organism To Another And Also From One Ecosystem To Another

Cycles Activity and Notes NAME: ______HR:_____ DATE:______

Introduction: Ecological cycles allow matter to be passed from one organism to another and also from one ecosystem to another. You may have learned about the water cycle in a previous science class. In this activity you will look at both pictures and websites to learn about ecological cycles: the water, carbon, nitrogen and phosphorus cycles.
