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 consumers which depend on the producers ( plants ) or the consumers ( The animals ) on feeding such as the humans and the animals .

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 food chain
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

Food web

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 .
