Dr. Forrester explains how all animals rely on producers, or plants, to provide a foundation for food chains and food webs.

Where do plants and animals get their energy from? Explore food chains and see how energy is passed from the sun to plants and on to first, second and third order consumers.

This live-action video program is about the term food chain. The program is designed to reinforce and support a student's comprehension and retention of the term food chain through use of video footage, photographs, diagrams and...

Any organism that gets its energy by consuming other organisms.

For ecosystems to function they need energy; and we can see how this energy moves through ecosystems with food chains. We also explore how the populations of predators and prey vary over time with predator prey cycles.

This video explores five fun facts about food webs.

Join the Amoeba Sisters in this longer review video as they review food chains, food webs, how energy flows through trophic levels (including the 10% rule), ecological relationships (including parasitism, mutualism, and commensalism),...

Food doesn't last. In days, sometimes hours, bread goes moldy, apple slices turn brown, and bacteria multiply in mayonnaise. But you can find all of these foods out on the shelf at the grocery store " hopefully unspoiled -- thanks to...

We're heading for a world population of 10 billion people -- but what will we all eat? Lisa Dyson rediscovered an idea developed by NASA in the 1960s for deep-space travel, and it could be a key to reinventing how we grow food.

“Food Webs” explains the movement of energy from producers to consumers to decomposers.

Producers, Consumers, and Decomposers explains the roles of producers, consumers, and decomposers within an ecosystem.

This video covers:

- The idea that trophic levels are just the different levels of a food
chain
- Trophic level 1 are called the
producers
- Trophic level 2 are primary consumers, trophic level 3 are called the...

In this video, we are going to look at a food chain and the different roles within that. So we will discover exactly what each of these words mean: food web, food chain, trophic level, producer, consumer, herbivore, carnivore, omnivore,...

This video explores the concepts of matter and energy in organisms and ecosystems. It explains how food provides energy for organisms, how plants use photosynthesis to convert sunlight into glucose, and how consumers obtain energy by...

This live-action video program is about the term food chain. The program is designed to reinforce and support a student's comprehension and retention of the term food chain through use of video footage, photographs, diagrams and...

Jean-Christophe Flatin, president of innovation, science, technology and Mars Edge at Mars and Daniela Hernandez, WSJ digital science editor, discuss the concept of "food as medicine" and new opportunities to make the foods we eat better...

This video is an educational program that teaches about producers in the ecosystem. The video also covers the process of photosynthesis that plants use to produce glucose, and it introduces the concept of a food chain to explain how...

Food Fighter is the inspirational story of one woman who abandoned capitalism in favour of social activism. Ronni Kahn founded OzHarvest to wage war on food waste, and to expose an inconvenient truth: that four million tonnes of...

James Rogers, founder of Apeel Sciences, and S2G Ventures Managing Director Matthew Walker discuss solutions that promise to take a bite out of the global problem of food waste with WSJ Deputy Chicago Bureau Chief Patrick McGroarty.

Lab food is more sustainable for the environment, but is it healthy? The short answer for cricket protein is yes, but we cannot yet know the longterm impact on our health. A food scientist shares his thoughts on the matter.

Lab Food...

Here's an exciting way to learn important facts and get ready for a life science test! In this episode we'll be looking at ecosystems.

A few additional ingredients and some chemistry is needed to ferment soy whey into Sachi alcohol. Let's explore how it works and see how people react to the final product.<br/>
Lab Food part 7/9

Could crickets be the new beef? Insects are protein-dense and have a small carbon footprint, which may make them a logical protein option in the future. Let's look at the environmental impact of different types of meat...

This video is a lecture presentation on the transfer of biomass in food chains. The presenter explains how processes carried out by living organisms can affect the amounts of biomass and energy transferred from one trophic level to...
