pollution affect in food chain because due to pollution food chain is distributed.and some how some participants of food chain are have declined so.........we should get aware of it and take some steps.
It depends. A food chain could be fairly long with about four or five steps in it, or a food chain could have just two.
I think what you are referring to is a food chain, It is a series of energy steps from plants to animals and more animals in the form of food.
The second and higher steps in a food chain typically consist of consumers, such as herbivores and carnivores, that feed on other organisms. These organisms further transfer energy up the food chain by eating lower trophic level creatures. Each step in the food chain represents a transfer of energy from one organism to another.
food chain
It is called a food web and also in steps called this primary, secondary, and tertiary.
the top of the pyramid
it's the plants or you can say grass 1- grass(primary producer or first step of food chain) eaten by....... 2- frog eaten by........ 3- snake eaten by........ 4- eagle
food chains are a series of steps in which organisms transfer energy,and a food web links all the food chains in an ecosystem together.
