Tuna sandwich trophic pyramid

This image is a diagram known as a trophic pyramid. This example shows the levels of an ecosystem that support the growth of tuna, which might be consumed by a human in a tuna sandwich. The diagram shows six levels in the 'pyramid' from phytoplankton through to humans, and visually depicts the size of the biomass at each ...

Cells and energy

Cells are like chemical factories. Discover the different ways cells get energy to carry out their daily operations. Learn about the different types of metabolic processes inside cells, such as those that break down molecules to release energy and those that assemble building blocks to make more complex components.
