Question

other insects cannot, but, a bumble bee has just enough weight to open up the snapdragon flower and pollinate. this adaption is an example of convergent evolution divergent evolution co - evolution speciation

Explanation:

Co-evolution refers to reciprocal evolutionary changes between interacting species. Here, the bumble bee's weight (allowing it to open snapdragon flowers) and the snapdragon's flower structure (requiring such weight for pollination) are adaptations that have evolved together due to their mutual interaction. This fits the definition of co-evolution, unlike convergent (unrelated species developing similar traits), divergent (related species evolving different traits), or speciation (formation of new species).

Answer:

co-evolution
