Algae in an aquatic food chain convert solar energy into 93,000 kilocalories of plant tissue. Which of the following values best
represents the amount of energy available for secondary consumers in the food chain? 1. 930 kilocalories
2. 9,300 kilocalories
3. 93,000 kilocalories
4. 930,000 kilocalories
The correct answer is - option 1. 930 kilocalories.
Explanation:
In every ecosystem, the energy is passed from one form to another and there is a lot of loss of the energy as heat in the cellular process. There is a transfer of only 10% of each level of the trophic level.
Algae is the producers in this aquatic ecosystem so the primary consumer will get 10% of the energy that is present in plant tissue (93000kcal) which will be 9300 Kcal and second producers will get 10% of this will be 930Kcal.
Thus, the correct answer is option 1. 930 kilocalories.
