When did angiosperm plants become abundant?

because they have pollens and flowers/fruits. The flowers are able to attract insects and this allows better transportation of pollen. Also, animals and insects may eat the seeds, and that would also be good transportation of the seed because the seed is usually excreted.
Why are there so many angiosperms?
Angiosperms and the animals they support have given rise to a terrestrial biota far richer than any that came before.

Why angiosperms are found in every habitat?
Angiosperms are considered to be one of the greatest examples of symbionts in nature, due to their many mutualistic relationships with pollinators, fungi, herbivores and others.
