4. How do we understand Symbiosis? Every ecosystem has many different symbiotic relationships. Each fills a niche. All symbiotic relationships are specific to the organisms. You can’t replace one with another. Every ecosystem has many different symbiotic relationships. Each fills a niche. All symbiotic relationships are specific to the organisms.

7. Mutualism 1. T here is a bird, the Egyptian plover, which cleans crocodile teeth by eating the left over food particles in the crocodile’s mouth.

8. So what do my relationships have to do with ecology? Ecology is all about the relationships within an ecosystem. Ecology is all about the relationships within an ecosystem. If the relationships work well the ecosystem is healthy. If the relationships work well the ecosystem is healthy. We all have relationships if they are healthy we are vibrant, productive, happy and fulfilled! We all have relationships if they are healthy we are vibrant, productive, happy and fulfilled!
