Curated OER
Biomass Energy
Junior ecologists relate how food chains and food webs route matter and energy through an ecosystem. They trace feeding levels of a food chain or food web through a pyramid of energy. As a reinforcement activity, learners construct three...

Building Ecological Pyramids
Looking for a fresh take on traditional food/energy pyramids? Conduct an innovative activity where pupils build their own! The lesson uses research data from Gorongosa National Park in Mozambique for a real-life safari touch. Scholars...

Energy Flow in Ecosystems
Emerging biochemists more fully understand the flow of energy in ecosystems as they explore the laws of thermodynamics and relate them to energy transfer in food chains. They also investigate heat loss from the human body and how...
NOAA
An Ocean of Energy
Young biologists trace the path of the sun's energy through marine ecosystems in the second part of this four-lesson series. Building on prior knowledge about producers, consumers, and decomposers young scholars are introduced to the...
University of California
Energy and Biomass Pyramids
Young scientists play tag as they act out the food pyramid in the ocean ecosystem. Energy circles pass from the smaller prey to the predators and at the end of the activity, a data chart and analysis questions allow pupils to apply their...
Curated OER
Dynamics of Ecosystems
A set of guided notes walks your biology or environmental studies learners through the dynamics of ecosystems. They write short answers to questions about the energy budget, food webs, trophic levels, and biogeochemical cycles. One way...
Curated OER
Ecological Pyramids
Students apply the ecological pyramids of numbers and biomass with an activity using topographic maps. For this trophic level lesson, students work in groups using a topographic map to determine the number of organisms that can live in...
Curated OER
Food Chains, Food Webs, Biomass Pyramids and Cycle
In this food chains worksheet, students complete a crossword puzzle by placing 16 terms into the puzzle that match the clues given. Students review food webs, biomass pyramids, and the water cycle.
Curated OER
Pyramid of Biomass
Students interpret data to demonstrate biomass and number pyramids. They use information to draw conclusions and examine an example of biological magnification.
Curated OER
Populations and Ecosystems
Seventh graders create a model of an ecosystem and label it to show structure and function. They research the food web of an aquatic animal and also trace energy flow from the primary producer up the food chain.
Curated OER
Ecology and the Conservation of Natural Resources Lesson 2
Students compare and contrast abiotic and biotic factors. They discuss how these factors effect ecosystems. They answer questions to complete the lesson.

Who Can Harvest A Walleye?
Seventh graders investigate the concept of how an ecosystem is put together while conducting research using a variety of resources. They correctly differentiate between a herbivore and carnivore by placing them in the order of hierarchy...
