Partially decayed plant matter found in bogs is called peat. Peat forms when organic material accumulates and is not fully decomposed due to waterlogged conditions in bogs, creating an important source of fuel and for ecological processes.

Plants that have partially decayed in water are called peat. Peat forms in waterlogged conditions where plant material cannot decompose fully due to lack of oxygen. Over time, this partially decomposed plant material accumulates and can be harvested for various purposes, such as fuel or horticultural use.
The top layer of soil, known as the organic horizon or O horizon, contains the most decayed organic material. This layer consists of partially decomposed plant and animal matter, such as leaves, twigs, and dead organisms.
The Topsoil
Decomposed particles from the earth are commonly referred to as soil organic matter. This organic matter is made up of partially decayed plant and animal material, along with microorganisms, that contribute to soil fertility, structure, and nutrient cycling.
Decayed plant and animal matter is known as organic matter. It is broken down by microorganisms and decomposers to release nutrients that can be reused by plants for growth and development. This recycling process is an essential part of nutrient cycling in ecosystems.
organic matter important to plant growth is humus.

In the formation of coal, peat has the lowest carbon content among the stages. Peat is the first stage in coal formation and is composed mainly of partially decayed plant matter.
