What are the key points to remember for the ecology topics in biology at GCSE level? And what diagrams are helpful?

When it comes to ecology there is quite a lot of content to cover, but some of the key points to focus on are the carbon and motives cycles (which have some great diagrams to support them), food webs, adaptations and sampling techniques. These topics feed into the rest of the content you will need to know such as tropic levels and global warming.
