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.

Paul Andersen describes how free energy is used by organisms to grow, maintain order, and reproduce. A brief discussion of the first and second law of thermodynamics is also included. Disruptions in the amount of free energy can cause...

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

This video explain how energy is passed throughout an exosystem and the levels of organisms.

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 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...

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

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

We tend to imagine there are connectings between things that we don’t understand. Quantum mechanics and consciousness, aliens and pyramids, black holes and dark matter, dark matter and dark energy, dark energy and black holes. Usually...

Pupil outcome: I can create and interpret pyramids of number to show the size of a population at each trophic level. Key learning points: - Food chains show the feeding relationships between organisms and the flow of energy through a...

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),...

How energy is passed through living things can be described as a food chain. Journey through a food chain, from primary producers at the bottom to tertiary consumers at the top. Biology - Ecosystems - Learning Points. A 'food chain'...

Coach Socrates reviews the oils and fat section of the food pyramid. He talks about why our bodies need oils and which oils are the healthiest to use. He talks about the different ways that people use butter, and then demonstrates 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...

Discover which foods are vital for a healthy diet. What should you be eating, how much, and why? Biology - Healthy Living - Learning Points. You need a balanced diet to be healthy. A balanced diet is varied and contains different amounts...

A VITAL Strategy For the Toughest Reading and Listening Questions

At a speed of 19 kilometers per second, the huge rock would cause quite a lot of damage if it circles back and hits Earth on its orbit around the Sun.

Swift 2 is a multi-paradigm programming language that has expressive features familiar to modern functional languages, and does not forget the object-oriented features of Objective-C. Things that took a block of code in...

This video explores the a fantastical theory that many ancient megalithic structures around the world, including the pyramids of Giza and Stonehenge, may have served as data storage units or communication devices with entities from...

Upon viewing the Nutrition video series, students will be able to do the following: Define nutrition as a science that studies the interaction of the human body and food. State the six major kinds of nutrients including: carbohydrates,...

Would a mile-high skyscraper ever be possible? Explore the physics behind some of the tallest buildings and megastructures in the world. -- In 1956, architect Frank Lloyd Wright proposed a mile-high skyscraper, a building five times...

TEOTIHUACAN FROM ITS FOUNDATION IN THE SECOND CENTURY B.C. TO THE PRESENT DAY, TEOTIHUACAN IN MEXICO HAS OCCUPIED A POWERFUL YET MYSTERIOUS PLACE IN THE CONSCIOUSNESS OF CENTRAL AND SOUTH AMERICANS. SITUATED IN THE HIGHLANDS OF CENTRAL...
