Second level consumers- about 10 units
Third level of consumers- about 1 unit
Explanation:
Food chain describes the feeding pattern of a group of organisms in an ecosystem. The food chain shows how one organism in one TROPHIC LEVEL feeds on another organism in another. As organisms are being fed on, energy is being transferred.
A food chain always starts with a PRODUCER, which occupies the first and lowest trophic level. It creates the energy transfer as it obtains energy via photosynthetic process. The flow of energy as shown by an energy pyramid is Producer----First level consumer----Second level consumer------Third level consumer.
However, only about 10% of the available energy is transferred and accessible by the next organism. This is because about 90% of the energy has been lost as heat when the organism undergoes metabolic processes. Hence, if 1000 units of energy was present at the producer level, 10/100 × 1000= 100 units will be available to first level consumers.
Also, 10/100 × 100= 10 units of energy will be available to second level consumers and finally 10/100 × 10= 1 unit of energy will be available to talk third level consumer.
