"O" horizon
Loam

"Loam means you have roughly equal portions of sand, silt and clay," he said. ... Silt loam has a little more silt in it. Clay loam has more clay in it."

What soil horizon contains mostly clay silt and sand?

E Horizon - This eluviation (leaching) layer is light in color; this layer is beneath the A Horizon and above the B Horizon. It is made up mostly of sand and silt, having lost most of its minerals and clay as water drips through the soil (in the process of eluviation).

the overall balanced equation

6co2 + 6h2o > c6h12o6 + 6o2

sunlight energy

where: co2 = carbon dioxide

h2o = water

light energy is required

c6h12o6 = glucose

o2 = oxygen

preservation because he preserves part of the land and preserves means save
