A) mice.
B) bees.
C) hummingbirds.
D) bats.

Hummingbirds. They have a huge beak thing to poke down the long tube. And they love red.

Mice come out at night

Bees have to land

C) One population of frogs mates in the deep water of a pond and another population of frogs mates on the shore of the same pond.
