13. Biosphere Biomes Ecosystem Community Population Organism They ALL relate to each other!

15. ENERGY flowing through an E C O S Y S T E M creates a simple FOOD CHAIN diagram.

16. Food chains – arrows show the direction of energy flow.

17. Relationships  The relationships between organisms in an ecosystem can be shown by a food web.
