This smart slide show outlines energy flow in ecosystems. It addresses the sun as the primary source of all energy, flows into explanations of photosynthesis and respiration, and explores trophic feeding levels and productivity....

Produce, consume, decompose...repeat! Examine how matter and energy cycles in ecosystems by watching a video discussing NGSS standard LS2B. The narrator explains the requirements of the standard at each grade level, plus gives tips to...

Twenty-two straightforward questions query your emerging ecologists on energy flow through ecosystems. They review abiotic and biotic factors, trophic levels, photosynthesis and cellular respiration, food chains, and primary...

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...

Middle or high school environmental studies classes will learn much from this presentation on energy in ecosystems. It covers the foundational topics of trophic levels, food webs, and nutrient cycles using informational text and...

Every living thing requires a food source, thus the interconnections in ecosystems become complex. Scholars learn about these interconnections in a presentation on energy flow. It starts with the sun and moves through many different...

How can you tell what an owl has eaten? Study the food chain and flow of energy in an ecosystem by dissecting an owl pellet and noting the bones found inside. Additionally, the lesson includes a game about consumers and producers with a...

Students explore energy and nutrient flow. For this science lesson, students diagram the flow of energy through food chains and food webs. Students discuss the importance of energy flow in Earth's ecosystems.

Why do energy pyramids only contain four to five levels? Individuals review food webs to begin discussing energy flow in ecosystems. Through discussion and a simulation, they explore photosynthesis and use this concept as a platform to...

Budding scientists work collaboratively to reenact energy flow in a food chain. Scholars take on roles such as producer and consumer and perform tasks that symbolize energy flow in order to provide evidence of how much energy passes...

Here is a practical activity for reinforcing understanding of energy flow in ecosystems. Learners identify whether each organism in a list is a producer or decomposer. They tell if each is an herbivore, carnivore, omnivore, or...

It's a jungle out there! Young biologists journey to Darien, Panama to examine the intricate relationships between the organisms that inhabit the jungle. Groups begin by demonstrating an understanding of energy flow in ecosystems, then...

The amazing process of a plant growing from a seed is the focus of this science lesson. Your class works in groups for a short time each day to document the growth of a plant they have sown from a seed. They utilize AlphaSmart devices,...

Rhinozilla is Mia's bearded dragon and the focus of this lesson on energy flow in an ecosystem. She uses him to explain the energy pyramid, from producers through third level consumers, and she likens the food chain to a video game. Mia...

Students determine the role of producers, consumers and decomposers in an ecosystem. In this biology lesson plan, students construct a wetland food web. They apply what they learned by playing a board game.

Young biologists trace the path of the sun's energy through marine ecosystems in the second part of this four-instructional activity series. Building on prior knowledge about producers, consumers, and decomposers learners are...

Students complete discussions and worksheets about the Hawaiian food chain. In this food chain lesson plan, students research decomposers, consumers, and producers.

When a minnow eats a piece of plastic, that garbage often tracks through multiple animals, causing harm to each as it passes through the food chain. Scholars learn about food chains, food webs, and energy pyramids with a presentation. It...

How is energy transferred within an ecosystem? What would happen to a food web if one of the organisms was removed? Elementary or middle school ecologists examine these questions and more in a comprehensive 5E learning cycle lesson....

Students explore energy flow in a food web. In this energy flow lesson, students investigate the relationships and energy flow in a food web.
