This ocean environment is characterized by long plants that are rooted on the ocean floor but grow upwards toward the surface.

a. the kelp forest
b. pelagic zone
c. benthic zone

sand 60

clay 10

silt 30

sandy loam should be dominated by the sand. as the amount of sand increased, the amount of slit needed to anchor the plants' roots to the sand will also be increased. even though the amount is very little, 10% part of clay is still necessary for proper oxidation.
