Wheat mill 
This is followed by the repeated grinding process with subsequent sieving of the
material to be ground
...
Biting 
For example, beetles have strong mandibles that allow them to chew through tough plant
material ...
Tundra Soil Characteristics and Composition 
The organic matter in tundra soil is derived from the decomposition of plant
material, as the cold temperatures and waterlogged conditions inhibit the breakdown of organic matter by microorganisms
...
Bog Ecosystems 
A bog is a type of wetland that accumulates peat, a deposit of dead plant
material ...
Fire and Vegetation 
Fire helps to control the growth of woody plants, prevent the accumulation of dead plant
material, and stimulate the germination of seeds
...
Grassland Soil Composition Analysis 
soil is typically sandy and low in organic matter, while temperate grassland soil tends to be richer in nutrients and organic
material ...
Social Wasp Behavior 
The queen wasp initiates nest construction by chewing wood fibers and mixing them with saliva to create a paper-like
material ...
Tundra Soil and Vegetation Health 
Soil Composition Tundra soil is typically composed of a thin layer of organic
material overlying a layer of permafrost
...
Role of Herbivores in Grassland Ecology 
Nutrient cycling: Herbivores contribute to nutrient cycling in grasslands through their consumption of plant
material ...
Wetland Conifer Forests 
The forest floor is often covered in a thick layer of organic
material, known as peat, which is created by the slow decomposition of plant material in the waterlogged conditions
