It gets used up on the way.
Only about 10% of the energy from the producer is passed on to the consumer.
90% of the energy is lost every time something is consumed.
food web
In an ecosystem energy passes from one feeding level to another. Producers are plants that occupy the first level in the ecosystem. They are the only organisms that can convert the sun's energy into chemical energy through photosynthesis. When plants are consumed, energy is passed on the herbivores and then carnivores. Without producers in the food chain there would be no energy produced for other consumers of the food chain, which is vital to daily life.
pyramid of energy
In the energy pyramid, 10% of the energy is passed up from producers, to 1st level consumers, to 2nd level consumers, etc. 90% of energy is lost.
Yes, it starts with the producers - plants, then to the primary consumers - herbivores and omnivores, then to the carnivores then to the decomposers, which breaks down dead bodies into nutrients essential for plant growth.
The level in a food web with the highest amount of total available energy is the producer. The producer is a photosynthetic organism that can harness the energy from light that generally comes from the sun. As the energy is passed from trophic level to trophic level, only about 10-20% of the energy is passed on, while the rest is lost as heat. For instance, if a producer had a total energy amount of 60 kj/m2yr, then the primary consumer would only be able to gain 6-12 kj/m2yr.
1% because if 10% moves on to each level, and 10% was passed on to the first level consumers, 10% divided by 10% equals 0.01 which is equivalent to 1%, so 1% of the original energy used by plants is passed on to second level consumers. :)
Any tropical forest is usually described in four layers. The emergent layer is a small number of trees which grow above the canopy layer. The canopy contain the majority of large trees. The understory layer is placed between the canopy and the floor, and the forest floor is the lowest layer.
All consumers obtain energy from producers. This is true even for carnivores because the energy is passed through every organism.
Photochemical energy is transformed into biochemical energy.
