Answer:
1. A horizon
Explanation:
The A horizon is considered the topsoil and contains inorganic and organic material called humus. This is the layer that supports agriculture. Areas with thin A horizons are often in deserts, tundra, and coniferous and tropical rain forests. Areas with thick A horizons are often grasslands, which can be used for agriculture, and temperate deciduous forests.
