Biological Communities
Living things work together in groups known as communities. These vary in size from very simple ones to very large. complex communities. A drop of water caught in the curved leaves of a plant is host to many bacteria and other organisms, and represents a small biological community. At the other end of the scale a large area, such as the Amazon rain forest, can also be considered a community.
One of the primary ways in which the organisms in a community interact is through food chains, and even more complex relationships called food webs. Communities are also tied together by the flow of energy and water and minerals. You may want to consider the cycles that occur in the natural world and how they relate to biological communities. The carbon cycle, the nitrogen cycle, and the water cycle are some possibilities.
You can explore many online resources related to biological communities, also known as ecosystems.
