Definition: the species that are so abundant that they have the biggest biomass of any member in the community
Example: In terrestrial ecosystems, the dominant species is always primary producers (plants). Another example is the American Chestnut Tree (in 1900s)
Extra Info: Dominant species can be removed from an ecosystem, and it can remain sustainable, but the biodiversity may decrease as a result (when American Chestnut Trees became extinct in 1950, seven species of insects that received resources from the tree went extinct as well).
