- They can contain different ecosystems
- E.g. within a tropical grassland biome there could be areas of open woodland, areas of swamp, lakes and grassland plains.
- This is an area with a distinctive climate and vegetation
- Energy Flows
- Energy moves between the organisms in an ecosystem
- Energy enters an ecosystem by photosynthesis
- The energy is stored in the plant and passed up the food chain when the plant is eaten
- This process continues throughout the ecosystem - when one organism eats another it receives the energy from that organism
- This means that energy flows between all the organisms in an ecosystem
- This process continues throughout the ecosystem - when one organism eats another it receives the energy from that organism
- The energy is stored in the plant and passed up the food chain when the plant is eaten
- Definition
- This means that energy flows between all the organisms in an ecosystem
