Consider two habitats with a flowering plant of which bumblebees are a main pollinator. In Habitat A, the bumblebee robs nectar without pollinating 50% of the time it visits a flower. In Habitat B, the bumblebee does not exhibit the nectar-robbing behavior. In which habitat does the plant species have greater fitness?

1.Habitat A
2.Habitat B
3.The plant fitness should be the same in habitat A and habitat B.

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.

the answer is d. embryo
