Question

: one species benefits from the interaction, and the other species is harmed but not necessarily killed example: ticks feed on other animals’ blood, which can hurt the other animals. done : one species benefits from the interaction, and the other species is neither helped nor harmed example: egrets rely on cows to stir up dirt and bring food to the surface, but cows do not benefit. done

Explanation:

The first description ("One species benefits from the interaction, and the other species is harmed but not necessarily killed") matches the ecological relationship of Parasitism (e.g., ticks on animals: parasite benefits, host is harmed). The second description ("One species benefits from the interaction, and the other species is neither helped nor harmed") matches Commensalism (e.g., egrets and cows: egret benefits, cow is unaffected). These are concepts in Biology (Natural Science subfield) related to species interactions in ecology.

Answer:

First dropdown: Parasitism
Second dropdown: Commensalism
