Energy? • What are the sources of energy we find in our homes? • What do you think the main source of energy is for our planet? • The sun is the main energy source of our planet. • Plants are the only organisms able to turn the sun’s energy into food energy. What do we call that process? • PHOTOSYNTHESIS!
Energy? • Where does your body get its energy? • Our body gets energy from the food we eat. • Let’s brainstorm everything we know about food.
Investigation: Food Chains • All animals eat plants or other animals to get they energy they need to live. • If a rabbit ate a carrot the food chain would look like this: • If you then ate the rabbit the food chain would look like this:
Investigation: Food Chains • Some animals eat only plants. They are called… • HERBIVORES • Some animals eat mostly meat. They are called… • CARNIVORES • Some animals rely on both plants AND meat for their energy. They are called… • OMNIVORES
Investigation: Food Chains • There is actually even more to this chain… • After a hawk dies, fungi (like mushrooms) and other decomposers break down the dead hawk, and turn the remains of the hawk into nutrients, which are released into the soil. • The nutrients (plus sun and water) then cause the grass to grow. • It's a full circle of life and energy!!
Food Chain Games • Practice making different types of food chains. • Chain reaction game • Food chain puzzle • What living things need & the food chain
Make your own food chain • Your food chain should have at least three organisms. • Make sure your arrows point in the direction the energy is traveling. • Label your organisms with the appropriate terms: • Producer • Omnivore • Carnivore • Herbivore • Decomposer
Food Webs • Do you only eat one kind of food? • Most organisms get energy from more than one source. • A diagram that shows how food chains connect and overlap is called a food web. • Turn your textbooks to page B23 to see an example of a food web. Answer the following questions…
Food Web Questions • Why are there no arrows leading to the blueberries? • Why are there no arrows leading from the owl? • What foods does the deer eat? • What foods does the fox eat? • Do you know of other animals that live in a forest such as this one? Would a complete food web for a forest be much larger or smaller than the one shown?
Food Web Games • Fill in the food web • Build your own food web • Scholastic food web game • Fun with food webs
Ernie Energy • Listen to the song about Ernie and write down any important information about his trip. • Now draw a picture in your spiral representing the trip that Ernie took.
