Question

threatened species determination - requires finding: - geographic boundaries in which a species could occur and outside of which species will not be able to survive - area of occupancy - actual geographic boundaries in which species are found (there may be several areas of occurrence in the extent of occupancy) - number of individuals concentrated within a geographic range

Explanation:

To solve this, we match the definitions to the correct terms related to threatened species determination:

First Blank (geographic boundaries for species’ potential occurrence):

The term for "geographic boundaries in which a species could occur and outside of which species will not be able to survive" is Extent of Occurrence. This refers to the total area a species could occupy based on habitat suitability, regardless of whether it is currently occupied.

Second Blank (actual geographic boundaries where species are found):

The term for "actual geographic boundaries in which species are found (there may be several areas of occurrence in the extent of occupancy)" is Area of Occupancy. This is the smaller, more precise area where the species is actually present (e.g., specific habitats or regions it inhabits).

Third Term (number of individuals in a geographic range):

The term for "number of individuals concentrated within a geographic range" is Population Size (or sometimes "Abundance"). This measures how many individuals of the species exist within its range.

Final Answers (filling the blanks):

• First blank: Extent of Occurrence
• Second blank: Area of Occupancy
• Third term: Population Size (or Abundance)

(Note: If the blanks are for the first two definitions, the first is "Extent of Occurrence" and the second is "Area of Occupancy".)
