Populations and Ecosystems

Jump into an exploration of marine ecosystems with the first lesson in this four-part series. After first learning about crustaceans, mollusks, and other forms of sea life, young marine biologists view a PowerPoint presentation that...

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...

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...

Plants. We can't live without them! Bill Nye discusses how every living thing relies on plants using a concept called the food web. In a very visual demonstration, he ties a cord from one picture to another on a three-dimensional...

A disgusting and direct description of detritus and decomposition is digested in this drill! Your life science class learns about the importance of decomposers in the food chain and finds out how one organism's trash is another...

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...

Rhinozilla is back to take your lesson plan on trophic levels a step higher! After showing the video on food chains (available through the See All Related Jams button), add to it by showing this one. It deals with omnivores and food...

With the forest as an example, Sam and Zoe talk about the components biotic and abiotic of an ecosystem. They also discuss the role of producers, consumers, and decomposers. This concise clip covers all of the basics. As an introduction...

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...

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...
