Measuring photosynthesis

This is a colour underwater photograph of marine scientist Candida Savage using a scientific instrument known as the diving-PAM. The diving-PAM is being used to measure photosynthesis in corals in Fiji. Candida Savage is wearing full diving clothing and equipment including mask, wetsuit and oxygen tanks.

Marine trophic pyramid

This image displays a type of diagram known as a trophic (or ecological) pyramid. This example depicts the organisms and the matter and energy flows in a typical marine ecosystem. The diagram shows six levels of organisms from primary producers through to the top carnivores, arranged in a pyramid. Also represented is the ...

Plants and increased levels of carbon dioxide

We know that most plants use carbon dioxide to make their own food. So what might plants look like in 100 years if carbon dioxide levels continue to increase - will they become enormous and overtake our backyards? View the possible effects of changes in atmospheric carbon dioxide on plants and, in turn, humans and other animals.

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.

Plant leaves

Leaves come in many shapes, sizes, colours and textures. Watch this clip to discover how leaves make their own food and transport energy to the rest of the plant. See how they can even be useful after they've fallen to the ground. Presenter Nick Hardcastle and some young helpers will also show you a fun, creative activity ...
