In this unit students explore major marine ecosystems by locating them on maps. Students use marine examples to learn about energy transfer through food chains and food webs and then they discuss how food webs can illustrate the health...

A collection of three lessons where students learn about abiotic factors in marine ecosystems, about marine food chains and biodiversity, and about marine food webs and trophic levels. Includes handouts, website links, and a vocabulary...

Students learn about energy and nutrient flow in various biosphere climates and environments. They learn about herbivores, carnivores, omnivores, food chains and food webs, seeing the interdependence between producers, consumers and...

Students learn about energy flow in food webs, including the roles of the sun, producers, consumers and decomposers in the energy cycle. They model a food web and create diagrams of food webs using their own drawings and/or images from...

Fourth graders will be able to name some plants and animals that live in Utah's desert, forest or wetland ecosystems.

Students learn about the feeding relationships in an estuary ecosystem with this interactive energy pyramid activity. A second activity involves research and a video clip to elaborate the learning.

Read a brief history of the use of DDT in the United States, its effect on wildlife, and the banning of the toxin in 1972 by the EPA.

Kids learn about the food chain and food web. How energy cycles and transfers through living organisms.

Students will create a food chain model and use it to describe the movement of matter among plants, animals, decomposers, and the environment. Resources include a detailed lesson plan, student handouts, pictures of a completed chain,...

Given illustrations, students will analyze the flow of matter and energy in food chains, food webs, and ecological pyramids.

Students will build a food web diagram and illustrate the movement of matter through a series of food chains. Resources include detailed plans, examples of student work, videos of the lesson in action, and sample food webs.

For this lesson, students learn about marine food webs and pyramids, and how energy flows through a marine ecosystem. They then research a marine organism and its role in a marine food web. The class pools their information to create a...

Explains what is meant by a tertiary consumer in a food chain and provides examples.

In this lesson, learners will choose an organism of their choice and research its life cycle, food chain, diet, and habitat, then predict how habitat change might affect the organisms living within it.

This lesson plan provides an eight-day flow of educational activities in which students use the Great Salt Lake ecosystem to explore food webs and how changes in living and nonliving factors affect different populations.

A suite of lessons focusing on the process of upwelling. Inquiry-based exploration of seasonal upwelling includes marine food webs, food production in the ocean, wind-driven ocean currents, and seasonal changes in biotic and abiotic...

Describes how a food chain works in a desert and how the Mojave desert food chain works in particular.

Explains what a food web is, the complexity of one in a rainforest, and how energy flows through a food web.

Read to understand how energy and inorganic nutrients flow through a food chain in an ecosystem.

Learn about the mysterious jellyfish blooms that have occurred in the world's oceans. Because the resulting alteration to the marine food web has had devastating effects, researchers grow and study jellyfish at the Monterey aquarium....
