Question

what is defined as \an individual unit that can interbreed within itself\?
community
ecosystem
species

To solve this, we analyze each option:

• A community is a group of different species in an area, not about interbreeding within a unit.
• An ecosystem includes living and non - living components, not focused on interbreeding.
• A species is defined as a group of organisms that can interbreed to produce fertile offspring (interbreed within itself).

C. species (assuming the options are labeled as A. community, B. ecosystem, C. species)
