Investigation 6 Part 2 Food-Chain Game 5/5/2016

* You will need your composition books today.* Bell work 35 May 5, 2016 * You will need your composition books today.* Take out your bell work paper, skip a line, write Thursday, and answer the following questions. You can use your composition books and text books to answer the questions. What do people use energy for? When you sleep, you feel refreshed. What could be happening to make you feel that way? 3. Where does the energy in food come from originally? Remember to write complete sentences when doing your bell work.

13. Uses of Energy What do people use energy for? 2. When a person is low on energy, what can he or she do to get more energy?

13. Uses of Energy What do people use energy for? Everything, because all life processes require energy. 2. When a person is low on energy, what can he or she do to get more energy? Eat food

13. Uses of Energy 3. What other ways can people get more energy? 4. When you sleep, you feel refreshed. What could be happening to make you feel that way? 5. Where does the energy in food come from originally?

13. Uses of Energy 3. What other ways can people get more energy? There are no other ways 4. When you sleep, you feel refreshed. What could be happening to make you feel that way? Maintenance activities go on during sleep. You feel energized, but you didn’t really get more energy. 5. Where does the energy in food come from originally? The sun

13. Uses of Energy 6. How does energy from the Sun become food? 7. Which category increases biomass? 8. In which category is food produced?

13. Uses of Energy 6. How does energy from the Sun become food? Light energy is captured during photosynthesis. Carbon dioxide and water are changed into energy-rich molecules called carbohydrates. Carbohydrates are food. 7. Which category increases biomass? Growth and reproduction 8. In which category is food produced? Growth and reproduction primarily; waste can be used as an energy source by decomposers.

14. Wrap up/warm up Return to your focus question 6.1 What are the kinds of work you do that require energy? Draw a line of knowledge and summarize your ideas about energy use.

1. Review food chain During this course we have been talking a lot about food chains and food webs. What is the difference between a food chain and a food web? What is being transferred in a food chain?

1. Review food chain What is the difference between a food chain and a food web? A food chain is a direct path of food interactions in an ecosystem, with one organisms at ach level of producers or consumer. A food web is all the feeding interactions between organisms in an ecosystem, with multiple organisms at each level. What is being transferred in a food chain? Energy in the form of food. In this activity, you will look at one food chain from Mono Lake.

2. Food-chain interactions Does everything in a food chain get eaten? Discuss in your groups 2. What could happen if all of the producers or all of the primary consumers in an ecosystem were eaten?

2. Food-chain interactions Does everything in a food chain get eaten? What could happen if all of the producers or all of the primary consumers in an ecosystem were eaten? The other organisms in that ecosystem would not have anything left to eat. We are going to investigate what it takes to keep the ecosystem intact and going. We want a sustainable ecosystem. Sustainable means the ecosystem lasts, or maintains itself, over a long period of time.

3. Focus Question 6.2 FQ 6.2 What is needed to sustain a food chain? Write the Focus Question in your notebooks, put it in your table of contents. FQ 6.2 What is needed to sustain a food chain? We will come back to it later to answer it.

4. Review Mono Lake organisms Turn to your Mono Lake food web in your notebooks. Find the planktonic algae What eats the planktonic algae? What is one of the organisms that eats the brine shrimp? What eats the California gulls?

4. Review Mono Lake organisms What eats the planktonic algae? Brine Shrimp What is one of the organisms that eats the brine shrimp? California gulls and most of the other birds. What eats the California gulls? Coyotes We are going to concentrate on four of these organisms: planktonic algae, brine shrimp, California gulls, and coyotes. These organisms represent one food chain within the more complex food web at Mono Lake.

5. Food-Chain activity You are going to participate in a simulation of this food chain with populations of those four organisms. There are name tags that label each organisms. Some will be brine shrimp, some will be California gulls, and some will be coyotes. The bag of popcorn represents planktonic algae eaten by brine shrimp.

7. Feeding When the game starts, the brine shrimp will try to eat their food, algae, by putting popcorn into their stomachs. (bags) The gulls will try to eat the brine shrimp by gently tapping them on the shoulder or arm. When a gull tags a brine shrimp, the gull takes the brine shrimp’s stomach, and the brine shrimp leaves the game. They coyotes will try to eat the gulls by gently tapping them on the shoulder or arm. When a coyote tags a gull, the coyote takes the gull’s stomach(s), and the gull leaves the game.

8. How to determine survival At the end of the round, you will combine the food in the stomachs you collected and look at the total amount. If your stomach is full enough, you survived. If you were eaten or didn’t get enough to eat, your organisms dies. Brine shrimp must fill their stomach to the bottom line. California gulls and coyotes must fill their stomach to the top line To be a sustainable ecosystem, there must be at least two brine shrimp, two California gulls, and one coyote left at the end of the round.

9. Roles There will be 3 groups, Yellow Brine shrimp Green gulls Pink coyotes. MAKE SURE YOU REMEMBER THE COLOR AND WHO YOU ARE ALLOWED TO EAT!!! You will get to play several rounds depending on time. Because you are moving around, bending over to pick up popcorn, be careful no pushing, shoving, or running.
