Bring on the ants! Players send leafcutter ants and mushrooms—two important rainforest decomposers—into the leaf litter that is built-up on the forest floor, in this interactive game from PLUM LANDING™. In the process, they make healthy new soil that will provide nutrients for other organisms.
In this lesson, students will be able to identify the producers, consumers, and decomposers and sort them with their group to create a food chain.
The classroom resource provides a video that will describe the interactions between organisms in a food chain. There is also a short test that can be used to assess students' understanding. Students can use the information presented in this video to create their own model that shows the transfer of matter between organisms.
The classroom resource provides a video that will describe the interactions between organisms in a food web. There is also a short test that can be used to assess students' understanding. Students can use the information presented in this video to create their own model that shows the transfer of matter between organisms.
The purpose of this lesson is to introduce students to the idea that energy is passed from one organism to the next in a food chain. This lesson will serve as proof that owls eat rodents and use this energy to survive.
The purpose of this lesson is to acquaint students with a type of ecosystem (the submerged aquatic vegetation of a bay) and how the different organisms of that ecosystem compete with one another for resources. Students will research plants and animals that live in the submerged aquatic vegetation (SAV) of a bay area. After researching the organisms, students will do class presentations and create a food web using pictures of all of the organisms. At the end of the lesson, they will discuss their ideas of organisms sharing food, space, water, air, and shelter.
This lesson is the second of a two-part series on the cycle of life. This series should help enhance student understanding of the flow of matter and energy and the interdependence of life by focusing on food chains and food webs. The first lesson in this series on food chains is Cycle of Life 1: Food Chain (http://sciencenetlinks.com/lessons/cycle-of-life-1-food-chain/). This second lesson will help students understand that some insects depend on dead plant material for food and that they interact with other organisms in various ways.
