Question

two species benefit from interaction with each other example: a hummingbird gets food from the nectar of a flower and then spreads the nectar’s pollen, helping the flower reproduce.

Explanation:

The scenario describes a mutualistic relationship where two species (hummingbird and flower) benefit. This falls under Biology (Natural Science subfield) as it involves ecological interactions and species relationships. The term for this interaction is "Mutualism", where both organisms gain from the association. The hummingbird gets food (nectar), and the flower gets pollinated for reproduction.

Answer:

Mutualism
