Planets are massive, so we use models to easily view our solar systems in schools and homes.
Their will be fewer competitors in the new habitat
Because it’s good for the environment to have a good balance and not to much of one thing
If we didn't have sun's energy there wouldn't be life on earth.Sunlight is what plants eat. Animals and bugs eat the plants that have sunlight in them. Humans and other animals then eat the bugs and the animals that ate the plants. Indirectly every living thing has sunlight feeding it.
Hope this helps!
