Learn about relationships between different organisms.
Trophic Interactions
Trophic interactions are the relationships between different organisms within an ecosystem
This is based on their feeding behaviour. This means, who eats who!
These trophic interactions make up food chains or webs.
Producers and consumers
Producers: Plants and algae make their own food through photosynthesis.
Consumers: Organisms get their energy by eating other organisms.
These trophic interactions maintain the balance of an ecosystem
Primary producers
Corals are the primary producers, capturing energy from the sun and providing shelter and structure for other reef organisms.
Herbivores
Parrotfish and surgeonfish are herbivores that graze on algae, helping to control its growth and maintain a healthy reef ecosystem.
Secondary and tertiary consumers
Moray eels and hawkfish are secondary consumers, that feed on tiny fish and zooplankton in the reef. Tertiary consumers are bigger fish that prey on the smaller fish and zooplankton.
Reef sharks are top predators that regulate the population of various reef-dwelling species.
Can you think of your own trophic interactions?
Coral reefs are incredibly diverse, and many more species and interactions can be found within these ecosystems!
