Explanation:

Each blank is filled based on standard soil science facts about the properties and composition of soil components:

1. Humus is decayed organic matter found in soil, and it holds nutrients from once-living organisms.
2. Clay's tiny particles have high water retention capacity.
3. Sand has large, porous grains that cannot retain water effectively.

Answer:

• Humus is decayed matter in soil. It contains lots of nutrients from former living things.
• Clay contains tiny particles of soil that hold water well and has some nutrients.
• Sand is made up of small grains of worn-down rock. It has few nutrients and does not retain water well.
