Energy Pyramids show how much energy is present at each level. It is a diagram that shows the relative amounts of energy within each trophic level in a food chain or web.
Biomass Pyramids represents the amount of biomass within each trophic level.
Numbers Pyramids show how many organisms there are at each tropic level.
Energy pyramids are probably the most useful of the three!

Ecological Pyramids
Diagrams of food webs only show qualitative information. Pyramids of numbers, biomass and energy provide us with quantitative information. The diagram below shows the appearance of these ecological pyramids for three food chains, all taken from the previous foodweb .
Ecological pyramids
There are points to note about each type of pyramid. All pyramids are pyramidshaped other than the exceptions given below.
Pyramids of number
Pyramids of number allow us to compare the number of organisms present in each trophic level at a particular time. Although pyramids of number are pyramid-shaped there are two important exceptions. Pyramids will be upside down or inverted if there are a lot of small animals feeding on a large plant. They are also inverted where an animal has a large number of small parasites feeding on it. One human, for example, can have a large number of head lice. In the diagram, the butterfly larva is being fed on by a large number of parasitic wasps.
Pyramids of biomass
Biomass is a measure of the total amount of living material present. Pyramids of biomass allow us to compare the mass of organisms present in each trophic level at a particular time. Pyramids based on biomass get over the problems of organisms differing in size. Most pyramids of biomass are pyramid-shaped, but there is one important exception which you should know about. This is when the producer is a small organism which multiplies very rapidly. In this case, the total biomass of the producers present at any one time may be less than the total biomass of the primary consumers. The pyramid will again be inverted.
Pyramids of energy
Pyramids of energy allow us to compare the amount of energy passing through each trophic level over a period of time. They differ from the other two types of ecological pyramid which measure the number and biomass of organisms present in each trophic level at a particular time. Pyramids of energy are always pyramid-shaped. There are no exceptions to this rule.
There are actually three types of ecological pyramids. There is the pyramid of energy, the pyramid of biomass, and the pyramid of numbers.

Numbers, biomass and energy
The concept is often associated with descriptions of food chains and food webs (Food Chains and Food Webs in an Ecosystem, Food Chain and Food Web Book Reviews). An ecological pyramid is an illustration of the reduction in energy as you move through each feeding (trophic) level in an ecosystem. The base of the pyramid is large since the ecosystem's energy factories (the producers) are converting solar energy into chemical energy via photosynthesis. A food chain can also depict a reduction in energy at each feeding level if the arrows, drawn between the different levels, continue to be reduced in size.

Systems biology studies the way biological systems work. For example, the human anatomical, cardiovascular, or respiratory system. When these are studied, medical advances and breakthroughs can be made.

Environmental studies involve the integration of various disciplines such as biology, sociology, economics, and political science to understand environmental issues comprehensively. This multidisciplinary approach allows for a holistic perspective on environmental problems, considering both natural and human dimensions. By drawing on diverse fields, environmental studies can provide more effective solutions to complex environmental challenges.
Centre for Environmental Studies was created in 1967.
Environmental studies is a field which studies human interaction with environment.
Environmental health studies focuses on the management of the environmental health issues and environmental science focuses on the management of the Environment.
National Institute for Environmental Studies was created in 2001.
environmental Engineering studies
The components of Environmental studies are based on five fundamental aspects. 1. environmental perception and awareness 2. environmental education and training 3. controll of environmental degradation and pollution 4. resource management 5. environmental impact assesment
"Green studies" would be a current metaphor for environmental studies.
Related areas of study include environmental studies and environmental engineering.
Tottori University of Environmental Studies was created on 2001-04-04.
Environmental studies is a section of educational training that focuses on the environment. Mainly, they study how humans interact with the environment.
Adam Joseph Lewis Center for Environmental Studies was created in 2000.
