Food Chains link together:
Producer ----> Primary Consumer ------> Secondary Consumer -----> Tertiary Consumer
- Only one organism per trophic level
- You cannot show an organism being an omnivore / cannot show organisms feeding at more than 2 trophic levels
- Food Chains show the flow of matter and flow of energy
4.5b Food Webs
The food web allows us to provide a better description of the ecosystem (ecosystems are community of organisms interacting) In this case interacting = feeding
Feeding at different trophic levels:
consequences
- organisms can have multiple predators
- may be feeding on multiple pray
- resulting to the food chains becoming linked.
