Question

1. a hummingbird drinks nectar from a flower and carries its pollen to other flowers. what is this an example of?

dispersive mutualism
commensalism
defensive mutualism
parasitism

Explanation:

• Dispersive mutualism is a symbiotic relationship where one organism gets food/nutrients, and the other gets help with dispersing reproductive structures (like pollen). The hummingbird gains nectar, and the flower gets its pollen spread for reproduction.
• Commensalism benefits one organism without affecting the other, which does not fit here.
• Defensive mutualism involves one organism protecting the other, which is not the case here.
• Parasitism harms one organism to benefit the other, which is not applicable here.

Answer:

dispersive mutualism
