The energy paths through the living organisms in the food chains and the food webs
There are food relations between all the living organisms , The living organisms are classified according to their feeding into the producers which depend on themselves to make their food such as the green plants and the green algae .
The decomposers which depend on the organic remains ( the dead bodies of the consumers or the producers ) on feeding , such as some bacteria and fungi and they help the environment to get rid of the remains of those bodies .
The food chains
There are food relations that connect between all the living organisms , These food relations are known as the food chains , The food chain is a path of the energy that transmits in a form of the food from a living organism to another one .
|The green plant is the producer of the energy for the consumers and the decomposers .|
The food chain begins with a producer , then the herbivorous consumer then the carnivorous consumer , then It ends with a decomposer organism that feeds on the carnivorous consumer after death .
A primary consumers eat the producers ( the herbivores ) , The secondary consumers eat the primary consumers ( the carnivores ) .
The tertiary consumers eat the secondary consumers ( the carnivores ) , And the scavengers are carnivores that feed on the bodies of the dead organisms .
You notice that it ends with a carnivorous consumer when the organisms of the food chain are alive .
The food webs
The food web is formed when a group of food chains connect with each other , The food web is a group of overlapping food chains , It represents the flow of the energy through the living organisms in the form of the food , When a group of the food chains connect with each other , they form a food web .
All the food chains and the food webs start with the green plant as it is the producer of the food ( energy ) as it makes its own food , and the green plant is the producer of the energy ( food ) for the consumers and the decomposers .
The importance of the solar energy for the producers , the consumers and the decomposers
The producers ( the green plants ) to make their own food by using the solar energy ( the sunlight ) which is stored in the food ( the carbohydrates ) in the form of the chemical energy .
When the consumers ( as rabbit ) feed on the producers , the stored energy in their food transfers to the consumers .
- By the death of the consumers , the energy transfers into the nature ( the environment ) through the decomposers which change the dead consumer bodies into the useful substances ( the fertilizers ) in the soil to help the plants with their growth .
The Energy paths
The energy paths are paths that show the energy transference in the form of the food from a living organism to another in the food webs and the food chains , In the food chains , The energy decreases gradually when it transfers from a living organism to another .
So , The highest amount of the energy is in the producers ( the green plants ) . and the least amount of the energy is in the last consumer , where each living organism consumes an amount of the energy to practise its vital activities .
