Spheres of the Earth There are four interconnected spheres on Earth: biosphere geosphere hydrosphere . atmosphere Matter cycles and energy flows through these four spheres. Matter cycles • Different forms of matter continually cycle through the four spheres. • Matter cannot be created or destroyed; it can be transformed and recycled. • Carbon can move through many different forms: ■ as glucose (C6H12O6) in organic matter ■ as methane (CH4) in decaying matter ■ as carbon dioxide (CO2) in the atmosphere Biosphere The biosphere represents all living components on Earth. Components include: all plants (e.g. trees, flowers and grasses) all animals (e.g. birds, mammals and fish) all fungi (e.g. mushrooms and molds) other examples The biosphere can be described as the total sum of all ecosystems.
