Question

which is the most important layer of soil ​

Answer 1

Answer:

topsoil

Explanation:

The world grows 95% of its food in the uppermost layer of soil, making topsoil one of the most important components of our food system. ... Without topsoil, the earth's ability to filter water, absorb carbon, and feed people plunges. Not only that, but the food we do grow will probably be lower in vital nutrients

Answer 2

Top soil

• The most uppermost horizon is the topsoil layer. The topsoil layer is made up of sand, silt, clay, and humus (organic matter that has been broken down).
• Humus is a rich, severely decomposed organic material made of dead plants, crunched-up leaves, dead insects, and twigs.
• Topsoil is home to living creatures and the materials they create or modify.
• Soil organisms like moles and earthworms, bacteria, and fungi combine and break down components to offer nutrition to plants, animals, and insects.
• Earthworms are very important because they dig into the earth, providing openings for water and air as well as allowing plant roots to grow.
