In the ongoing energy debate, biomass energy is getting a lot of play among politicians. To understand the concept, it first helps to understand the bio pyramid.
Bio Pyramid
All of the organisms in the world follow orders of classification. Whether you choose to put them into groups of plants and animals, herbivores and carnivores, or any other of the many different types of classification systems, organisms can be put into many groups in order to understand their relationship to one another. One way to classify organisms is to put them into their order, or hierarchy, in the food chain. In this way, we can see how animals and other organisms relate to each other based on what they consume.
There are several different ways to look at the food chain, and one important and useful tool in this area is the bio pyramid. A bio pyramid is a graphical chart that shows the comparative mass of the consumers to the producers in the food chain. This can be helpful in determining how energy is transferred to the top levels of the pyramid from the bottom levels.
Each level in a bio pyramid is composed of a trophic level. Trophic levels are groupings of different 'consumer' groups, such as primary producers (usually just plants or other photosynthetic organisms) rising all the way up to carnivores (such as humans). While a typical biological pyramid might group these consumers in order of energy produced, a bio pyramid shows them in order of total mass from highest to lowest. This often means that the primary consumers, such as the plants, are at the bottom because they are more numerous and take up more mass. The levels are built upon then by how many upper level organisms could survive based on the level below. An example can be seen in this sea bio pyramid:
It would take 1,000,000 kg of phytoplankton (1st level), to feed 100,000 kg of zooplankton (2nd level), to feed 10,000 kg of shrimp (3rd level), to finally feed 1,000 kg of large fish. The final level, the 5th, would only be able to have 100 kg of shark supported by the levels below.
In this way, a bio pyramid shows the inefficiency of the food chain, and lets researchers know that if a level was able to be skipped (such as a shark dipping down and eating shrimp instead of fish), more energy would be conserved and the food chain would lose less energy along the way. Given this fact, a bio pyramid is an important tool when looking at the laws of conservation of energy among different classes of organisms. |
