Question

one species benefits from interaction, and the other species is harmed but not necessarily killed
example ticks feed on other animals blood. which can hurt the other animals
two species benefit from interaction with each other
example a hummingbird gets food from the nectar of a flower and then spreads the nectars pollen, helping the flower reproduce
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

Explanation:

To solve this, we analyze each ecological interaction:

First Interaction (Hummingbird and Flower):

• Description: “Two species benefit from interaction with each other”
• Example: Hummingbird gets food (nectar), flower gets pollen spread for reproduction. Both benefit. This is mutualism (a type of symbiosis where both species gain).

Second Interaction (Ticks and Other Animals):

• Description: “One species benefits from interaction, and the other species is harmed (but not necessarily killed)”
• Example: Ticks feed on other animals’ blood (benefit), harming the host. This is parasitism (one benefits, the other is harmed).

Third Interaction (Egrets and Cows):

• Description: “One species benefits from the interaction, and the other species is neither helped nor harmed”
• Example: Egrets benefit (get food stirred up by cows), cows are unaffected. This is commensalism (one benefits, the other is neutral).

Filling the Blanks:

1. For the hummingbird-flower interaction, the term is Mutualism (matches “two species benefit”).
2. For the tick-host interaction, the term is Parasitism (matches “one benefits, one is harmed”).
3. For the egret-cow interaction, the term is Commensalism (matches “one benefits, one is neutral”).

Final Answers (assuming dropdowns for each):

1. (First dropdown) $\boldsymbol{\text{Mutualism}}$

3. (Third dropdown) $\boldsymbol{\text{Commensalism}}$
