In a particular food chain if producer produces 25000 kcal energy than what amount of energy is available to third trophic level of organism of that food chain ???
Answers
Answer:
25 kcal will be available to the animals in the third trophic level
Explanation:
This is because of the 10% rule. The first trophic level will get 10% of the energy of the producers and so on.
First trophic level- 2500 kcal
Second trophic level- 250 kcal
Third trophic level- 25 kcal

Answer
Amount of energy available to third tropic level of organism of that food chain is 25 Kcal.
Explanation
According to 10% law, only 10% of the energy is available at the next tropic level.
Example:- If the energy available at producer level is 1000J then at next level only 10% of 1000J like 100J is. So, only 10% of energy transferred to next tropic level while 90% of energy is used by present tropic level in it's life span.
As per given condition in question,
In a particular food chain if the producer produces 25000Kcal energy then we have to find the amount of energy that is available to the third tropic level of organism of that food chain.
Producres → Primary Consumers → Secondary Consumers → Tertiary consumers
Let's take a example to understand it.
Carrot → Rabbit → Fox → Lion
Here, Carrot is producer, Rabbit is primary consumer, Fox is secondary consumer and Lion is tertiary consumer.
The Carrot produces 25000Kcal energy. If a Rabbit eats the carrot then the energy available in it will be 2500Kcal (only 10% of the energy). If a Fox eats the Rabbit then the energy transferred in it will be 250Kcal.
And in last if the Lion eats the Fox then 25Kcal of energy will be transferred from Fox to Lion. Here, Lion is the third tropic level of organism. So, only 25Kcal of energy transferred in it.
In the above example; one organism eat other organism. This sequence is known as Food Chain.
