Light through a window is not direct sunlight as some of the light is diffused and reflected as it passes through the window, reducing its intensity. Light through a window is the most direct form of light available indoors, but is usually at least 50% less intense than direct sunlight outdoors.
As shown in the question above, protein breakdown releases the amino acids that make it up. These amino acids become free amino acids. These amino acids cannot be stored, so they can be quickly expelled from the body (when they are in excess and will not be necessary), they can also be degraded through oxidative degradation that will allow them to be reused in the manufacture of other proteins, or they can also be used as source of energy when the individual has been in court for a long time.
Minerals from the topsoil leach down into the subsoil. Volcanic activity heats the rock fragments in the subsoil and releases minerals. Groundwater flows through the subsoil and deposits minerals. The bedrock below the subsoil is broken down into smaller particles.
Fungi are either saprophytes or parasites
