Flowering plants are
a. gymnosperms
c. angiosperms
b. laurasians
d. archaeopteryx

The flower eventually turns into a fruit and we can then eat the fruit.

Interacting group of various species in a common location. for example, a forest of trees and undergrowth plants, inhabited by animals and rooted in soil containing bacteria and fungi, constitutes a biological community.
