Learn all about ecological pyramids and how to show quantitative data about relationships between species.

New ReviewA video entitled "Ecological Pyramid Models" which uses the energy, numbers, and biomass pyramid models to illustrate how energy moves through ecosystems.

Explore food chains, food webs, energy pyramids, and the power of biodiversity in this ecology video by the Amoeba Sisters! This video also introduces general vocabulary for the unit of ecology.

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),...

In this video Paul Andersen explains how matter moves from the environment into living organisms and back into the environment. Food webs are used to show how matter and energy move through organisms. Ecological pyramids show that...

In this video Paul Andersen explains how energy flows in ecosystems. Energy enters via producers through photosynthesis or chemosynthesis. Producers and consumers release the energy from food through cellular respiration. An...

This video covers:

- The idea that biomass is just the mass of living organ
isms
- Pyramids of biomass show the amount of biomass at each trophic level of a
food chain
- Why the amount of biomass decreases as you...

This video is a lecture presentation on pyramids of biomass. The presenter explains the concept of biomass and trophic levels in a food chain. The video provides a graphical representation of the relative amounts of organic matter found...

The video discusses the important ecological concepts of trophic levels and biomass. The video provides an example of a food chain, from grass plants as producers to apex predators that have no predators of their own. The video explains...

Enric Sala shares glorious images -- and surprising insights and data -- from some of the most pristine areas of the ocean. He shows how we can restore more of our oceans to this healthy, balanced state, and the powerful ecological and...

It describes the role of biological agents for controlling pests. It describes genetically modified organisms (using Bt microbe) and their uses as biocontrol agents.

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...

The video is a lecture on farming and fishing, with a focus on increasing the efficiency of food production. The video discusses various techniques and methods to increase the transfer of energy between levels in a food chain, including...

In this section, I talk about the sun as a source of energy, consumers vs. producers and cycles found in nature
