Ecology 6,2 - Feeding relationships

Photosynthesis

Producers - Plants are the basis

• Green plants produce food using photosynthesis
• Animals consume food
• Producers are always the first part of the food chain

Consumers

Animals consume (eat) substances made by plants (glucose) 

Primary consumers: herbivores - eat the producers (plants)

Secondary consumers: carnivores/omnivores - eat the primary consumers

Cycle continues up the food chain.

Scavengers

Scavengers eat dead material - dead animal or plant are used as food

Remains left by the scavengers are broken down by bacteria and fungi

Breakdown agents: return nutrients to be reused again. Always bacteria and fungi 

Nutrient cycle

The carbon cycle
