Describe the pyramid of energy with the help of a diagram.
Show Hint
Solution and Explanation
The energy pyramid represents the flow of energy across trophic levels in an ecosystem.
Explanation:
-The producers (plants) are at the base and have the highest energy content.
-Primary consumers (herbivores) obtain energy by consuming plants.
-Secondary and tertiary consumers feed on herbivores and other carnivores.
-Energy is lost as heat at each trophic level due to metabolic activities.
Key Features of Energy Pyramid:
-Only 10percentage of energy is passed to the next trophic level (as per the 10percentage Law).
-Energy flow is unidirectional (does not recycle).
-The pyramid is always upright, as energy decreases at higher trophic levels.
Top Questions on Ecology
- Given below are two statements:
Statement I: In an ecosystem, there is unidirectional flow of energy of sun from producers to consumers.
Statement II: Ecosystems are exempted from the law of thermodynamics. - Given below are two statements:
Statement I: Fig fruit is a non-vegetarian fruit as it has enclosed fig wasps in it.
Statement II: Fig wasp and fig tree exhibit a mutual relationship as the fig wasp completes its life cycle in the fig fruit and the fig fruit gets pollinated by the fig wasp. - Which of the following is the unit of productivity of an Ecosystem?
