The energy paths through the living organisms in the food chains and the food webs

 

You should know that there are food relations between all the living organisms .

 

We have known that 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 consumers

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

 

The food chain stars with a producer .

You should know that there are food relations that connect between all the living organisms , These food relations are known as the food chains . 

 

You should know that 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 .

You should know that 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 . 

The consumer tropic levels .

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 .

You should know that 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 .

 

You should know that 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 

 

• It is very important to 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 .

• You should know that 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 is transmitted in the form of food from a living organism to another .

You should know  that 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 , You notice that the energy decreases gradually when it transfers from a living organism to another .  

 

So , You should know that 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 .
