How does soil smell? Is it aromatic, foul-smelling, or without a scent?

Can you see any dead creatures or plants in the soil when you see under the microscope?

When plants and animals die, they become food for decomposers like bacteria, fungi and earthworms. Decomposers or saprotrophs recycle dead plants and animals into chemical nutrients like carbon and nitrogen that are released back into the soil, air and water.
