How do decomposers help to conserve mass and energy?
Decomposers use energy from sunlight to produce their own matter, which supplies other organisms with food.

Decomposers produce 90% of the heat needed for lower trophic levels.

As decomposers break down dead plant material, they convert up to 90% of the plants’ energy into sunlight.

As decomposers break down an organism, they release some of the organism’s matter back into the environment to be used again.

Early 18th century british industries were generally small scale and relatively unsophisticated. most textile production, for example, was centred on small workshops or in the homes of spinners, weavers and dyers: a literal ‘cottage industry’ that involved thousands of individual manufacturers. such small-scale production was also a feature of most other industries, with different regions specialising in different products: metal production in the midlands, for example, and coal mining in the north-east.two illustrations of 18t
