Because during sleep animals can recuperate and gain new strengths so they can tackle the challenges of the new day. Sleeping has protective functions for the brain because it removes toxins that build up during the day. Furthermore, sleep is helpful because the animal can rest during sleep and be ready for each new day.

What do you think the most interesting animal in the world is and why?
insens350 [35]

Answer:

Humming birds are one of the most interesting animals in the world. Some of them are so small that they are often mistaken for bumblebees. They're known to dive underwater and quickly dive right out while flying, and they eat more than they weigh to prepare their travel across an entire ocean non-stop. On top of all of this, they can be pretty rare depending on where you live, and they're really fun to watch.

Hope this helps you out :)
