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.
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.
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 food chain, food web, and energy pyramid are all models that show feeding relationships and allow us to make predictions. Compare and contrast the strengths and weaknesses of each model by filling in the table below.
In “Food Webs Activity: Building a Food Chain,” you built a food chain and learned how energy flows through trophic levels. In this part of the activity, you will complete a food web by modeling the energy flow between organisms.
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 Webs and Chains. Overview: This activity sheet will familiarize your students with food webs and chains, along with the changes that can happen when parts of the food web are altered. Each animal plays a critical role in their habitats. That role may be as a key part of the food web.
