1 The Marine Food Chain By: Whitney Hughes

2 Content Area: Science Grade Level: 4 Summary: The purpose of this instructional PowerPoint is allow the students to learn about the marine food cycle, and then recall that information in an interactive activity. Learning Objective: Given multiple-choice questions, students will be able to classify a specific species by their diet with 100% accuracy. Content Standard: Classify organisms as carnivores, herbivores, or omnivores. Accomplishment: Being able to determine how many organisms meet their energy needs by their physical characteristics and abilities.

3 Facts For this activity you will need to gather information about the marine food chain. This information will be used to answer questions later on. Here are a few things you will need to do while on the site. When you arrive to the website there will be a video that you can watch or skip. The Tabs you will need are the Marine Food Chain tab and the Seafood Decision Guide tab. To view more information about the species you will need to click on each food chain level Once you have read about each level, you should go to the Seafood Decision Guide to check out even more important information about the animals in that level.

4 Let’s Get Started! Now you know what to look for, let’s show you were to go! When you are done gathering enough information you can come back here and go to the next page. Go Here

5 Question #1 Tilapia, Oysters, Mussels, King Crab and Shrimp are all eaten in restaurants, and they are considered to be_______ because they eat __________. carnivores; Zooplankton, Phytoplankton and Scallops omnivores; Seaweed, Sea grass, and Clams herbivores; Zooplankton and Parrotfish herbivores; Seaweed, Phytoplankton and Sea grass

6 Correct! These tiny animals are herbivores because they do not eat other animals. Instead, they eat plants like Phytoplankton, Seaweed and Sea Grass.

7 Question #2 Cod, Monkfish, Salmon, Yellowfin Tuna, Swordfish, Rainbow Trout, and Blue Crab are larger and faster than most of their competition and some have no predators but humans. This means they are… Level 1 carnivores Level 4 omnivores Level 4 carnivores Level 3 omnivores

8 Correct! Level 4, also known as the Top Predators level, is the home of the largest, fastest animals underwater. This level contains carnivores like Sharks, Mahi Mahi, Seals, Barramundi and Halibut as well!

9 Question # 3 Squids, Pink Shrimp, Catfish, American Lobster, Flounder, Pollock, Sardines and Sole… are smaller carnivores because they are food for bigger carnivores. eat carnivores and herbivores eat zooplankton All of the above

10 Correct! These smaller carnivores are food to the larger carnivores in Level 4. They eat carnivores like themselves and herbivores like Zooplankton.

11 Conclusion In this lesson the students have learned how various animals underwater meet their energy needs and what level they are placed on the food chain. The students have also had the chance to display their knowledge of classification, by classifying groups of animals as either carnivore, omnivore or herbivore. In the future students can use the physical characteristics of a specific underwater animal or species to figure out their level on the food chain and diet facts, like they did in this activity.
