Sub-index of pages on biomass, pyramids, energy transfer (there is some overlap of the 7 sections)

(1) Introduction to energy and biomass transfer in food chains

(2) The crucial role of photosynthesis in the formation of biomass

(3) Important definitions, food chains, trophic levels and decomposers - examples explained

(4) Food webs and interdependence - examples explained

(5) Pyramids of numbers - how to construct them - examples explained

(6) Pyramids of biomass, construction, examples explained, why biomass loss in a food chain?

(7) Calculations of efficiency of biomass and energy transfer

Summary of ideas

Biomass refers to organic material derived from plants and animals, which can be used as a source of energy.

Biomass is transferred through the food chains from plants to animals.

It includes materials like wood, agricultural waste, and even animal manure.

Biomass can be burned directly for heat or converted into biofuels for electricity generation and transportation.

It plays a significant role in renewable energy, as it harnesses the chemical energy stored in organic matter through processes like combustion, gasification, and fermentation.
