The Mayans mainly lived where there were no lakes or rivers. Because of that, they had to do something to adapt or they wouldn't survive. They adapted to their environment by doing things like collecting rain water to use for crops.
When two species occupy the same niche, they compete for all the resources they need. The superiority of one species over another forces others to adapt and endanger them. This is called conflict elimination.
No two species can have exactly the same niche. Otherwise, you will be in direct competition for resources. In this case, one species is better than the other. When a lost species fails to adapt, it leads to extinction.
The competitive exclusion principle states that two species cannot occupy exactly the same niche in a habitat. In other words, different species cannot coexist within a community if they compete for the same resource.
