Only about 10% of the energy available at one level of the food chain is available for use by organisms in the next level.
For example, if you begin with an energy level of 2000, only 200 would be available at the next level, 20 at the next, and 2 at the next.
10% of the energy the eaten animal/plant has.
The amount of energy lost along the food chain varies a lot. It primarily depends on how many steps there are between producer and consumer.
What is the average amount of energy that passes from one feeding level to the next in a food chain
Not all the energy from a producer transfer to a secondary consumer because some of this energy is lost along the way.
heat
The four main stages of a food chain are: Producer, consumer, secondary consumer and tertiary consumer. The producer is a plant, which receives energy from the sun and converts it into glucose through the process of photosynthesis. (carbon dioxide + water = glucose + oxygen. The consumer is normally a herbivore - it eats the plant and gets some of the energy from the producer (some is lost through processes like respiration). The secondary and tertiary consumers are carnivores, and energy continues to be lost as the food chain continues. This loss of energy can be represented as a pyramid of biomass.
In the producer, energy is lost through growth, respiration and other life processes. It's the same in the consumer - excretion, respiration, movement, growth and other life processes all account for the vast amounts of energy that are lost in a food chain. This explains why food chains don't normally last longer than 4 stages - producer, consumer, secondary consumer and tertiary consumer.
Energy in an ecosystem flows in whats called the 10% rule. Meaning, as you move up the pyramid 10% of energy is lost.
10% 1% Energy from sun(100%)---->Producer--->Primary consumer-->Secondary consumer (90%) 9% 0.9%
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..
Less than 1000, in any case, since some energy is lost. The exact amount lost varies from case to case.
The top predator. Only 10% of energy moves from one level of the food pyramid to the next. When heat comes from the sun. 90% of it is lost to the environment, 10% is consumed by the plants (primary producer). As a primary consumer ingests the plant, 9% of the original heat from the sun is lost to the environment and the primary consumer receives 1%. The secondary consumer receives .1% and .9% is lost. This leads to the top predator receiving less than any organism below it.
