as we go up the food chain, of course, the energy will decrease...
it is because, from the primary producer, the primary consumer consumes it until the consumer will become the producer... and the cycle preceeds.. the energy will decrease because of the cycle..
an energy pyramid
If the number of phytoplankton decrease the food chain would decrease in the ocean.
Decrease in higher levels.
decrease the number of hawks
By. There genetics
the fox will decrease its numbers
the food chain and food web has someone or something eating each other.
Energy is lost at each step of a food chain through processes like respiration, heat loss, and waste production. As a result, only a fraction of the energy from one trophic level is passed on to the next, leading to a decrease in available energy as you move up the food chain.
The hawk, depending on where it Is in the food chain, will decrease the amount of animals below it i.e. rabbits, squirrels, ect. and/or it will be over populating the animal above it on the food chain therefore making the food chain and way of life not balanced.
The rat can be contained in both food web and food chain depending on each.
You can see a food chain if you watch animals eat each other
Energy and biomass decrease as you move up the food chain due to the second law of thermodynamics, which states that energy is lost as it moves through trophic levels. Organisms higher up in the food chain have less energy available to them compared to those lower down.
