Rabbits are called primary consumers, consuming plants, or in this case, grass (yes, they don't just eat carrots. In the wild they eat grass). Grass is a plant, and it depends on photosynthesis to make its own food. To make the food, it requires energy from the sun. To look more on this, look up some stuff about photosynthesis in your school science textbook. Without the sun, there would be no energy that the grass needs for photosynthesis to occur, henceforth, the grass will die. Without the grass (or any other vegetation, for that matter), rabbits will not be able to survive, since their food source diminishes and will disappear quickly. Therefore, the rabbits depend on the sun for the energy that it provides to its food source.
Also without the sun, the rabbits would freeze to death :P.
Positive reinforcement is based on two facts about human nature: people appreciate recognition, and they B<span>. WANT TO KNOW HOW WELL THEY ARE DOING. Hope this helps!</span>
Please if this is for school don't use my exact words change them a little. Use a thesaurus. Other than that I give the right for you to use this. Just don't want you to get in trouble.
The Civil War was a fight against America itself. Yes it was a war against ourselves. The north and south disagreed on several different things. The north wanted to stay together and the south wanted freedom from the north. In the personal opinions of southern people we believe that we fought harder, we cared more, and we should've won. Even though the loss was unfortunate some of us still have our southern pride and wish we had won to this day.
Hope this helps.
