- Classification
- Classification is Organising Living Organisms into Groups
- They help us to understand how organisms are related and how they interact with each other
- Phylum, class, order, family, genus and species
- A genus is a group of closely related species. Species is a group of organisms that can be interbre
- Classification systems can be natural or artificial
- Artificial classification systems are based on appearance rather than genes. They're used to identify organisms

- Pyramid of Biomass and Numbers
- Each bar on a pyramid of biomass shows the mass of living material at that stage of the food chain - basically how much all the organisms at each level would weigh if you put them together.
- Biomass pyramids are almost always pyramid-shaped because biomass is lost at each stage in the food chain
- Each bar on a pyramid of biomass shows the mass of living material at that stage of the food chain - basically how much all the organisms at each level would weigh if you put them together.
- Energy Transfer and Energy Flow
- Energy from the Sun is the source of energy for nearly all life on Earth
- Plants use a small percentage of the light energy from the Sun to make food during photosynthesis. This energy then works its way through the food chain as animals eat the plants and each other.
- Interpret Data on Energy Flow
- Plants use a small percentage of the light energy from the Sun to make food during photosynthesis. This energy then works its way through the food chain as animals eat the plants and each other.
- Interactions Between Organisms
