There are only two main types of physical weathering:<span>Freeze-thaw occurs when water continually seeps into cracks, freezes and expands, eventually breaking the rock apart.</span><span><span>
</span></span><span><span>Exfoliation occurs as cracks develop parallel to the land surface a consequence of the reduction in pressure during uplift and erosion.</span></span>
Answer: The first law of thermodynamics establishes that energy cannot be created neither destroyed.
Explanation:
So the grasshopers eat the grass to gain energy and then the birds eat the grasshopers to gain energy as well so by doing that they are just passing the energy to one another to power muscles and other body parts which follows the laws of thermodynamics that energy is not created but transfered from one system to another.
