Why is the soil rich in a deciduous forest?
A
fallen leaves make compost (leaf litter)
B
dead trees provide food for decomposers
C
fallen pine cones add minerals
D
light shines through bare trees
Explanation: 

Detailed explanation-1: -Did you know that fallen leaves can become a valuable garden resource? You can turn these leaves into compost. Although low in essential plant nutrients like nitrogen, the leaves still contain small amounts of all the nutrients plants need and are a valuable source of soil-improving organic matter.

Detailed explanation-2: -Fill with fallen leaves, ideally mixed with a few grass cuttings and add Vitax Compost Maker, two or three handfuls, as you go. Moisten the mix if dry and punch a few holes in the bag with a fork: compost needs some air. Now stack up the bags in a corner and leave them for a year or more.

Detailed explanation-3: -Answer: Plants are organic in nature. So, the fallen leaves decompses in the soil and form humus. This humus is rich in minerals which helps to maintain the fertility of the soil.

Detailed explanation-4: -The leaf litter in forests acts as a protective layer for soil conditions. It creates a physical barrier between the soil surface and atmosphere that reduces soil drying, responds to atmospheric temperature fluctuations, and reduces erosion from precipitation events.
