Bees are commonly found near flowering plants.<br> (a) Describe how bees help plants to reproduce.
siniylev [52]

Answer:

bees like flowers because they have pollen in their wings, and it makes them happy, and that’s nice. They make beautiful little things that can be used to make honey.

Explanation:

The foundation of the best honey is flowers and pollen. When they’re all in bloom, it’s a wonder for bees to come to them—not because of their beautiful colours but rather for how much sweetness there is in them. The smell alone makes every person nearby fall in love with bees. The only downside? The flowers die within weeks when exposed to too much pollen. They can only take so many blooms before it becomes too toxic for humans to eat, even if they don’t have to go through the hassle of killing a human to obtain them.

But that doesn’t mean bees hate the sight of flowers.

It has been said that flowers are what make people happy. That they can make anyone smile despite the circumstances. And maybe if people saw more flowers they would be happier? But it doesn't always work like that.

In this case, the members of Jane's organization chose another goal (rescuing potbelly pigs) instead of losing their jobs after the initial goal (rescuing bunnies) was accomplished.
