Question

fill in the blank: _______ is a group of similar organisms that can breed or produce offspring. genus species family kingdom

Explanation:

In biology (a subfield of Natural Science), the definition of a species is a group of similar organisms that can interbreed and produce fertile offspring. Genus is a taxonomic rank above species, family is a higher rank, and kingdom is a very broad taxonomic category. So the correct term here is "Species".

Answer:

B. Species (assuming the options are labeled A. Genus, B. Species, C. Family, D. Kingdom; if the original options had different labels, adjust accordingly, but based on the content, the correct answer is the option with "Species")
