  "term": "Niche preemption",
  "field": "Chemistry",
  "definition": "A process in ecology where an early-arriving species or individual establishes itself in a habitat and consumes or controls resources, thereby preventing other species from colonizing or thriving in that same niche. This mechanism can lead to competitive exclusion, where one species outcompetes others for limited resources. It is a form of interspecific competition that influences community structure.",
