Energy is needed for aquatic animals to perform basic survival tasks. In animals, energy is obtained through food. Plants obtain energy from the sun and convert it to food, and all living things obtain and transfer energy by participating in food webs. Food webs show the transfer of energy from the sun to producers which then transfer their own food to consumers. In this lesson students will learn the structure of a basic food chain. They will learn the vocabulary involved with producers and consumers. They will then understand how multiple food chains combine to form a more complex food web. Students will have access to IFXs so they can pick out animals and create their own food chain. A 360 video on ecosystems is also included in this lesson.
Use animal and underwater IFXS to show examples during discussion. For example, I used a clownfish, shark, whale, octopus, mollusk, starfish, freshwater fish like bass, sea otter and many others.
