7 kwi 2020 · Pyramid of Energy Packet. Every organism needs to obtain energy in order to live. For example, plants get energy from the sun, some animals eat plants, and some animals eat other animals. A food chain is the sequence of who eats whom in a biological community (an ecosystem) to obtain nutrition.
Describe the differences between a food chain and a food web, and give an example of a food web in a specific ecosystem. Discuss the role of producers, consumers, and decomposers in an ecosystem and how they are interconnected through food chains and food webs.

Grade Level: 7 Curriculum Links: Science and Technology Time Needed: 40 minutes – 1 hour Learning Goal To understand food chains/webs and how living things are connected in an ecosystem. Students will critically think about factors that can affect the balance of the ecosystem.
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.
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.
ecosystem is shown in diagrams called food webs and food chains. A food chain represents a series of organisms connected by where they obtain their energy. The energy source the producers are first in the food chain; then the series of organisms that eat other organisms to obtain energy follows in the chain .
