The following standards are covered: 4th Grade Life Science
2. All organisms need energy and matter to live and grow.
As a basis for understanding this concept:
-Students know plants are the primary source of matter and energy entering most food chains.
-Students know producers and consumers (herbivores, carnivores, omnivores, and decomposers) are related in food chains and food webs and may compete with each other for resources in an ecosystem.
-Students know decomposers, including many fungi, insects, and microorganisms, recycle matter from dead plants and animals.
3. Living organisms depend on one another and on their environment for survival. As a basis for understanding this concept:
-Students know ecosystems can be characterized by their living and nonliving components.
-Students know that in any particular environment, some kinds of plants and animals survive well, some survive less well, and some cannot survive at all.
