Adaptations and interdependence using Online Video

With this topic, you'll study the adaptations, interdependence, and food-energy flow of organisms in pond, forest, and grassland communities. You will also study the adaptations, interactions, and food-energy flow of organisms in desert, swamp, seashore, and man-made ecosystems. Use our 4 online elementary educational video titles to explore some of the diverse ecosystems that make up our planet: forests, grasslands, and pond communities. Also explore some of the other diverse ecosystems that make up our planet: deserts, swamps, seashores, and man-made communities. Learn why an ecosystem's plants and animals are dependent upon one another for their existence, how their varied adaptations enhance their chances for survival, how food energy flows from organism to organism, and how human actions can affect natural environments.

Learning Objectives:

• Learn what food energy is and how it is produced.
• Study the flow of energy through plants and animals of a natural community and investigate how plants and animals are adapted to their environments.
• Examine the interdependence of organisms in natural communities.
• Examine how predators relate to food chains.
• Study how nonliving factors affect the plants and animals within an ecosystem and investigate how plants and animals are adapted to their environments.
• Discover how humans can affect natural environments.
