Why are there fewer and fewer organism at the each level of the food chain?

The life at the top of the food chain eats the life at the bottom of the food chain. In order for this process to continue (instead of ending in starvation), the animals at the top of the food chain must be fewer in number than those lower down in the food chain.

Another Answer:
Looking at the Food Chain as a Competitive Pyramid, the higher you go, the more competitive the species, i.e. less likely to exist peacefully with peer species competition, due to distribution of resources. From a predatory diet standpoint, it takes a certain number of prey to sustain 1 predator, a certain number of that predator species to support a predator on the next tier up, and so forth.

Because they are small and are eaten first

In a food chain how much energy in transferred to each level?
90% is used by the organism, 10% is transferred to the successive organism.
What is a food chain level?
A food chain runs off of different levels - each having one living organism in it, per food chain. The levels indicate a section where energy is used up by an organism - namely the one that attained the energy.
Why does each level in a food chain contains less energy than the level below?
Because each consecutive levels contains fewer organisms than the level below
What is trophy?
In science it is explaned as a group of organisms that occupy the same position in a food chain. Each organism could be called a trophy of that level.
What do you think would happen if the plant at the beginning of food chain were sprayed with a poisonous chemical?
all organism are dependent on plant s directly or indirectly,so posion will spread in each and every level of food chain
Why do you see fewer and fewer animals at each higher trophic level?
Only about 10 percent of energy at any given level will make it to a higher one.
Do the biomass of organisms in a typical ecological pyramid increases at each level?
The biomass of each organism decreases with each level. With less energy at higher trophic levels, there are usually fewer organisms as well. Organisms tend to be larger in size at higher trophic levels, but their smaller numbers result in less biomass. Biomass is the total mass of organisms at a trophic level.
What organism connects both ends of a food chain?
Decomposers connect both ends of a food chain.
What does a biomass pyramid represent?
A pyramid of biomass shows how much energy the organism on a food chain is getting from its food.
Why do food chains rarely have more than 5 trophic levels?
Energy is lost to the surroundings as the food chain goes from one level to the next, so there are fewer organisms at each level in the food chain. Eventually there would be no animals left for another animal to eat eg: grass----->rabbit----->fox----->? 100 10 1
Can fewer organisms be supported at each level because there is less?
food/energy
Why do fewer organisms suported in each level because?
less energy and pubs
