Pre-trip lesson worksheet Refresh Your Memory: Food Chains and Food Webs 1. Take a dish containing animal ingredients you just ate as an example to complete a food chain. (If you are a vegetarian, you can invite your classmates to provide you with a dish) Example ① Dish: Beef and choy sum stir-fry ② The animal I ate: Cows
LABEL THE FOOD WEB. Label each organism based on its position in the food web: = Producer, 1 = Primary Consumer, 2 = Secondary Consumer, 3 = Tertiary Consumer, 2) Then label each animal as: H = Herbivore, C = Carnivore or O = Omnivore. D = Decomposer (Some may have more than one label.) Oak Tree. Squirrel.
Select four cards to create a food chain, starting with a producer. Label the trophic level of each organism in your food chain as follows: producer, primary consumer, secondary consumer, tertiary consumer. Record your food chain in the space below using species names and arrows.
Worksheet: Food Webs. In this worksheet, we will practice interpreting the interdependent relationships of organisms in ecosystems using food webs. Q1: Each link of the food chain is named according to what the organism eats and how it contributes to the energy of the ecosystem.
the types of food humans eat. Discuss and compare eating meat (carnivores), with vegetarians (herbivores). Explain how the same is true in the ocean and give examples, like sharks ( carnivores) and seahorses (herbivores). Discuss how animals who eat both are called omnivores like the Green turtle, and some are scavengers (crabs).
Ecological Pyramids Worksheet 1. Give one example of a food chain that exists in nature. 2. In an ecological pyramid, what happens to energy, biomass and # of species as you move up? Why? 3. What is biomass? 4. In an ecosystem, can there be more carnivores than herbivores? Explain why or why not? 5. What is the 10% rule? What is its significance?
Food Web. A food web shows how energy is passed on from one living thing to the next. It shows the feeding habits of different animals that live together in an ecosystem. In the food web pictured on the left, energy is passed from the grass to the mouse to the snake to the hawk.
