The positive connotation for noisy it think would be "participative".
The definition, according to Merriam-Webster is as follows:
Definition of participative<span>. : relating to or involving participation; especially : of, relating to, or being a style of management in which subordinates participate in decision making.</span>
<span>B is the correct answer. Being able to research successfully and organise your ideas helps you transform a vague idea in your mind into a coherent piece of writing.

Since bees help pollinate plants, a lack of pollination could prevent certain species of vegetation from growing. Therefore, the plants could be driven into extinction. These plants act as a food source to many animals, so if the animals have nothing to eat, they'd die off as well. Consequently, our own food supply of crop and animal would decrease.
