1 Food Chains and the Organisms in them!!!!! Copyright 2014-all rights reserved-www.cpalms.org

2 DO NOW!!!! Energy Flow Dominoes 1.Get into groups of 4. 2.Each group will receive a set of Energy Flow Dominoes. 3.Each member is to have 5-6 dominoes. 4.Whoever has the “Start” domino places it down first and reads the clue on the table. The person with the answer places it down next to the clue. 5.Continue until there are no more pieces left. 6.The “Stop” domino should be at the end!!!! If it’s not go back you did something wrong!!!!! Copyright 2014-all rights reserved-www.cpalms.org

3 1. How Organisms Get Matter and Energy -The ultimate source of the energy for life on earth is the sun. -Energy is the ability to cause change. Copyright 2014-all rights reserved-www.cpalms.org

4 -Matter and energy flow (move) through the environment in cycles. -Animals and plants depend on these cycles to get the food and nutrients they need to survive. -There are 2 main categories of organisms in the environment; autotrophs and heterotrophs. Copyright 2014-all rights reserved-www.cpalms.org

5 2.Heterotrophs are consumers; they must eat to get food. Ex: Lions, Humans, Rabbits. Copyright 2014-all rights reserved-www.cpalms.org

6 1.Autotrophs are producers; they make their own food through a process called photosynthesis. Ex: Trees, plants, algae. Copyright 2014-all rights reserved-www.cpalms.org

7 10% Rule When one animal feeds off another, only about 10% of the available energy is transferred.  There is a loss of energy in the form of heat in the process.  Additional loss of energy occurs during respiration and movement of the organisms before they are eaten.  More and more energy is lost as one moves up through trophic levels. Copyright 2014-all rights reserved-www.cpalms.org

8 Trophic Level  A trophic level is each level in a food chain. Copyright 2014-all rights reserved-www.cpalms.org 1 st Trophic Level 2 ND Trophic Level 3 rd Trophic Level

9 Trophic Levels  First trophic level = producers(autotrophs)  Second trophic level = primary consumer(heterotrophs)  Third trophic level = secondary consumer(heterotrophs)  Fourth trophic level = tertiary consumer(heterotrophs) Copyright 2014-all rights reserved-www.cpalms.org

10 Food Chain  A food chain is the series of organisms showing feeding relationships. A food chain usually begins with a green plant (producer) which is eaten by an animal (consumer). The arrow means 'is eaten by', and shows the flow of energy along the food chain. 10 Producer -> Consumer 1 -> Consumer 2 -> Consumer 3 -> Herbivore Carnivore Carnivore Copyright 2014-all rights reserved-www.cpalms.org

11 Food Web A network of interrelated food chains in a given area 11 Copyright 2014-all rights reserved-www.cpalms.org

12 CHECKPOINT QUESTIONS!!!!!! Copyright 2014-all rights reserved-www.cpalms.org

13 Is this organism a autotrpoh or heterotroph? If it’s a heterotroph what type of consumer is it? Which trophic level is it in? HeterotrophCarnivore3 Its eating a primary consumer. Copyright 2014-all rights reserved-www.cpalms.org

14 Is this organism a autotrpoh or heterotroph? If it’s a heterotroph what type of consumer is it? Which trophic level is it in? Explain why. HeterotrophDecomposer2 It is consuming a dead producer Copyright 2014-all rights reserved-www.cpalms.org

15 Is this a autotrpoh or heterotroph? If it’s a heterotroph what type of consumer is it? Which trophic level is it in? Explain why. Autotroph 1 It makes it own food and is eaten by consumers. Copyright 2014-all rights reserved-www.cpalms.org

16 Is this organism a autotrpoh or heterotroph? If it’s a heterotroph what type of consumer is it? Which trophic level is it in? Explain why. heterotroph-Herbivore2 It is eating a producer. Copyright 2014-all rights reserved-www.cpalms.org

17 Identify the possible food chains and the organisms on each trophic levels.

18 We Do– WE ARE ALL CONNECTED  Everyone will receive an organism and a task card for that organism. You will have 10-15 minutes to research the organisms answering the following questions.  Independent Organism Research Question.  1. What type of organism am I? (producer,consumer,decomposer)  2. Who are my natural predators?  3. How do I obtain energy?  4. What is my natural habitat? Copyright 2014-all rights reserved-www.cpalms.org

19 WE ARE ALL CONNECTED 1.Each student will have their organism taped to their shirt. 2.Each student stands in a circle and introduce yourself as the plant or animal you represent. 2.Each student stands in a circle and introduce yourself as the plant or animal you represent. 3. The student with the sun picture should stand in the center of the circle. 4.The ball of yarn represents the energy flow in this ecosystem. As each student throws the yarn ball, he/she will explain the transfer of energy that took place using essential vocabulary and the 10% rule using 1000 kJ as the starting point. 5. The student representing the sun holds on to the end of the yarn and tosses the ball of yarn to someone who can use that energy. 6.When a student receives the ball of yarn, he or she should hold a piece of the yarn and throw the ball to someone else that could use the energy. 7.When the yarn reaches a carnivore, break it off. This represents a food chain. 8.Toss the yarn to the sun to start another food chain. Continue making chains until every classmate holds at least one strand of yarn.

20 You Do  Question the following 1.How many food chains did we create? How many food webs did we create? Explain the difference. 2.Why is a food web a more complete picture of the feeding relationships in an ecosystem than a food chain? 3.Identify and describe an ecosystem in or around your home. List all the biotic and abiotic factors interacting there and explain how you think they affect each other.
