ecological pyramid

this time i kana post about the ecological pyramid that I learned in class three ..


Ecological Pyramid
Trophic structure of the ecosystem can be expressed in terms of the ecological pyramid. There are three types of ecological pyramids, the pyramid of numbers, pyramid of biomass, and energy pyramids.
a. Pyramid amount
Organisms with each trophic level - each can be presented in a pyramid number, as we are the first trophic level organisms are usually the most abundant, while the trophic level organisms in the second, third, and further decreasing. It can be said that in most normal communities, the number of plants is always more than herbivorous organisms. Likewise the number of herbivores is always greater than the number carnivore level 1. Kamivora level 1 is also always more than the carnivore level 2. Pyramid this amount is based on the number of organisms at each trophic level.

b. Pyramid of biomass
Often pyramid modest amount less helpful in demonstrating the energy flow in ecosystems. A more realistic depiction can be served with a pyramid of biomass. Biomass is a measure of weight of living matter in a certain time. To measure the biomass at each trophic level, the average weight of organisms at each level should be measured and then the number of organisms at each level are predicted.

Biomass pyramid fusion mass function describing the whole organism in a particular habitat, and is measured in grams.
To avoid damage to the habitat it is usually only a few samples were taken and measured, and then calculated the total biomass. With measurements like these will get more accurate information about what is happening in the ecosystem.
c. Energy pyramid
Often pyramid of biomass does not always give the information we need about a particular ecosystem. Others with energy pyramid is based on observations made in a long time. Energy pyramid is able to provide the most accurate picture of energy flow in ecosystems.

In the energy pyramid decline in number of consecutive energy available at each trophic level. Reduced its energy at each trophic occur due to the following.
1. Only a limited number of foods have been arrested and
eaten by the next trophic level.
2. Some of the food you eat can not dicemakan and
expelled as waste.
3. Only partially digested food becomes part of the
organism's body, while the rest are used as
energy sources.
Energy can be defined as the ability to do work. Energy obtained organismee of food consumed and used for his activities.
The sunlight is the main energy source of life. Plant chlorophyll utilize sunlight for photosynthesis. Organisms that use light energy to convert inorganic substances into organic matter called kemoautotrof Organisms that use energy from chemical reactions to make food called kemoautotrof
The energy stored in food is used by consumers for the activities of life. Liberation of the energy stored in food is done by oxidation (respiration).
Group autotrophs organisms are an important food for heterotrophic organisms, the organisms that can not make their own food such as humans, animals, and certain bacteria. Food heterotrophic organisms form of organic matter that is so.
