food chains

• Food webs show how organisms are connected to one another by what they eat, including both predator-prey relationships and herbivore-plant interactions.
• Energy flow diagrams illustrate where energy comes from and goes within an ecosystem.
• A food chain is the pathway that energy flows through an ecosystem.
• Energy moves from producers (plants) to consumers (animals).
• The sun provides energy to plants through photosynthesis.
• Consumers obtain energy by eating other organisms or parts of plants.
