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.

Pupil outcome: I can describe and explain the relationship between predator and prey populations. Key learning points: - Predators are hunters and prey are hunted. - Different factors can affect the population sizes of predators and prey...

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...

Pupil outcome: I can understand the natural processes that occur within a small-scale ecosystem in the UK. Key learning points: - An ecosystem is a natural system in which plants, animals and their non-living environment interact. -...

Pupil outcome: I can understand how natural changes and human activities affect the balance of small-scale ecosystems. Key learning points: - Ecosystems are finely balanced and can be affected by changing one component. - College Lake is...

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...

- Pyramids of biomass show the amount of biomass at each trophic level of a
food chain

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.

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

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.

The video is a lecture presentation on trophic levels in ecosystems. The presenter defines trophic levels as feeding levels in a community or ecosystem and explains how they can be used to organize feeding relationships. The concept of a...

This is a lecture presentation on feeding relationships in ecosystems. The presenter discusses the interdependence of different organisms in a community and the consequences of a change in that community. Using a specific community as an...
