Students will study the following concepts based on this lesson plan: the area an organism lives in must provide it with its basic life requirements and the ability of the habitat to do so is affected by abiotic and biotic factors. Abiotic factors in the environment are explained in terms of light, temperature, precipitation, and the process of soil formation. The types of biotic organization covered include populations, communities, ecosystems, the biosphere, food chains, and food webs. The lesson plan provides objectives, skills, time needed, a content outline, materials, significant terms, a glossary, and a field activity to study microhabitats. The site is part of a group of lesson plans whose main goal is for students to develop an understanding of the interdependence of all organisms and the need for conserving natural resources.
