Plant & Animal InterdependenceWeek 9
Directions1.Prepare your desk for science.2.Use voice level 0 (no voice) to skim through textbook pgs. 78-83 to remember what we discussed yesterday. Pay attention to the vocabulary words in yellow!
Targets & Warm UpTargets:Students will understand how the parts of an ecosystem interact.
Warm Up: What is an ecosystem?
Ecosystem (pg. 79)
• All the living and nonliving things in an environment and the many ways they interact
Can you use the words we have learned to describe this picture?
ecosystem, living, nonliving, habitat, population, community,
niche

Once you are finished with the Table of Contents, go to page 28 and 29 and add the title and date to the top of the page.
What is the main energy source for life on Earth?
How do plants use sunlight energy?How does this energy get passed on to animals?
Energy in Plants and Animals
• Producers: organisms that make (produce) their own food
• Consumers: organisms that eat (consume) other living things– Herbivores– Carnivores– Omnivores
Herbivores
Carnivores
Omnivores
Producer or Consumer?If it is a consumer, what type of consumer is it?
Food ChainThe process by which energy moves from one type of living thing to another
•In a food chain, organisms transfer energy by eating and being eaten•Where does this energy come from?
Food Chain• Always begins with energy from sunlight
(even if you don’t see it on the actual chain)• Producers come after the energy from the sun• Consumers follow the producers
• The arrows point from the “eaten” to the “eater”
Can you make a food chain?

Food Chain Video
DecomposersOrganisms that break down the waste and remains of dead plants and animals•Dead plants and animals are broken down and put back into the soil, air, and water•Living plants use these materials and then pass them on to animals
Examples: bacteria, fungi, and insects
Food Chain with a Decomposer
Producers, Consumers, and Decomposers
Food WebA system of overlapping food chains in which the flow of energy branches out in many directions.
Can you make a food web?
Reflection questions
• How do producers, consumers, and decomposers interact?
• How do food chains and food webs show interdependence?
Targets (Revisited)
Students will understand how the parts of an ecosystem interact.
