Final answer:
Trophic mutualism involves one species providing nutrients or food to another species. Habitat mutualism involves one species providing a habitat or shelter for another species. Service mutualism involves one species providing a service or behavior that benefits another species.
Step-by-step explanation:
Trophic mutualism is a type of mutualism where one species provides nutrients or food to another species. An example is the relationship between mycorrhizal fungi and plants. The fungi help the plants absorb nutrients from the soil, while the plants provide the fungi with sugars produced through photosynthesis.
Habitat mutualism is a type of mutualism where one species provides a habitat or shelter for another species. An example is the relationship between ants and acacia trees. The ants live in the hollow thorns of the acacia trees, and in return, they protect the trees from herbivores.
Service mutualism is a type of mutualism where one species provides a service or behavior that benefits another species. An example is the relationship between cleaner fish and larger fish. The cleaner fish remove parasites and dead skin from the larger fish, keeping them clean and healthy.
