The limits to the abiotic conditions that a species can tolerate distribution range of tolerance fundamental niche realized

The correct answer is "range of tolerance."The range of tolerance refers to the limits to the abiotic conditions that a species can tolerate. It represents the range of environmental factors, such as temperature, pH, salinity, or moisture, within which a species can survive and reproduce. The range of tolerance is an important concept in ecology as it helps to understand the distribution and habitat requirements of different species.The other options are related but distinct concepts:1. Distribution: This refers to the geographic locations or areas where a species is found or can be found. It is the spatial pattern of a species' presence or absence in different regions or habitats.2. Fundamental niche: This is the full range of physical and biological conditions under which a species can survive and reproduce, including its range of tolerance. It represents the potential habitat or environmental conditions that a species can occupy, without considering the presence of other species or competition.3. Realized niche: This is the actual habitat or environmental conditions that a species occupies in the presence of other species and competition. It is the portion of the fundamental niche that a species can actually use, given the constraints imposed by other species and ecological interactions.In summary, the range of tolerance specifically refers to the limits to the abiotic conditions that a species can tolerate, while the other options are related but distinct concepts in ecology.
