Overview of Topics
Decomposition means breaking things down. It happens when complex stuff turns into simpler stuff. This is really important for nature. Decomposition is like a makeover for materials in nature. Bacteria, fungi, and other tiny living things start this process. They eat dead things to stay alive. When plants and animals die, they become raw materials for decomposition. This creates useful stuff like nutrients, carbon dioxide, and water. Dead plants and animals are called detritus. Microbes change detritus into useful stuff. They are like nature’s cleanup crew.
Factors Affecting Decomposition
Here are the key factors that influence how fast things break down:
- Type of Stuff: Some things break down quicker than others. For example, mossy stuff decomposes slowly because it has tough chemicals in it.
- How Warm or Cold it Is: The temperature affects the tiny organisms that break stuff down. Different places have different temperatures, which changes how many of these organisms there are.
- How Much Air There Is: Tiny living things need air to break stuff down. In wet areas where there isn’t much air, different tiny organisms work on breaking things down.
- Soil’s Sourness Level: The soil’s acidity level affects the growth of the tiny organisms.
- Stuff in the Dirt: After things break down, certain chemicals like potassium and calcium get released into the soil. These chemicals help the tiny organisms grow and influence how fast things decompose.
- How Wet the Soil Is: Water in the soil helps the tiny organisms do their job. So, whether the soil is dry or wet affects how fast things break down.
Steps in Decomposition
- Breaking down debris into tiny pieces by tiny creatures is called fragmentation.
- Leaching happens when nutrients dissolve in water and settle in the soil, becoming unavailable.
- Catabolism is when bacteria and fungi enzymes break down debris into simple nutrients.
- Humification is the making of dark, organic stuff called humus that sticks around for a long time and acts as a nutrient stash.
- Mineralization is when tiny organisms break down humus to make simple nutrients.
All these decomposition steps happen together on debris. Decomposition needs oxygen and happens faster when debris has lots of nitrogen and water-soluble stuff.
Warm and wet places are best for decomposition because microbes like it there. Cold and airless conditions slow decomposition, so organic stuff piles up.

FAQs on NCERT Solutions for Class 12 Biology Chapter 14 Ecosystem 14.3 Decomposition
What is a decomposition process?
Decomposition refers to the process of breaking things down. It usually involves complex organic matter breaking apart into simpler inorganic substances. This process is vital for ecosystems to function properly.
What is an example of decompose?
Here are a few instances of breaking shapes in everyday situations: Dividing a pizza into slices. This involves separating a round shape into sections. Ripping an A4 sheet of paper into two pieces. This means splitting a rectangle into two smaller rectangles. Cutting a lemon slice in half.
What is simple decomposition?
The most basic type of decomposition reaction happens when a compound breaks down into its parts. For instance, when we heat up red solid mercury (II) oxide, it breaks apart to form mercury and oxygen gas.
Why is decomposition important?
Over time, if leaves and other plant parts don't break down, a lot of nitrogen would stay trapped in them. This would leave insufficient nitrogen for the plant to grow new leaves, stems, and wood. Additionally, dead leaves and wood would pile up on the ground without ever decaying, covering its surface indefinitely.
