• A. A- IV, B- III, C- II, D- I
• B. A- II, B- IV, C- I, D- III
• C. A- II, B- I, C- III, D- IV
• D. A- I, B- II, C- III, D- IV

Answer 1

The correct option is B A- II, B- IV, C- I, D- III

A) A species is a breeding unit. They are reproductively isolated from the individuals of other species.

B) An ecological unit includes all organisms sharing he same ecological niche. An ecological niche is the mode of existence that a species has within an ecosystem.

C) A karyotype is the number of chromosomes in the nucleus of a eukaryotic cell. Organisms showing similar karyotype belong to a particular genetic unit.

D) An evolutionary unit consists of species having similar structural and functional characteristics.

Hence, the correct match is A- 2, B- 4, C- 1, D- 3.
