Ill give you 60 points & brainliest
1.describe the role of animals in the water and carbon cycles.
2.compare the costs and benefits of solar power to that of nuclear power. ( include two costs and two benefits.)

1. In the Carbon Cycle all living things play a part. The animal store water within themselves playing a huge role.Without microorganisms in the soil and ocean, all life on earth would cease. All organic (living) things, plants and animals, contain carbon and play a role in the carbon cycle. 

2. With solar power you take natural resource that there is always enough of and you use it to heat and light your own home. There is no pollution when using solar power unlike nuclear powers. But Solar Pannel's cost many thousand dollars. They also take a long time to set up and plug in.  

That is false even though water expands when frozen nothing changes at all
