Question

Which of the following depicts the pattern of flow of energy and materials through an ecosystem?

• A. Food chain
• B. Pyramid of numbers
• C. Pyramid of biomass
• D. None of these

Answer 1

The correct option is A Food chain

An autotroph produces the food and herbivores consume them as their own food. then carnivorous feed upon the herbivores and in this way energy and material are transferred through an ecosystem that is from producer to consumer. This chain of energy flow consists of many organisms on the different trophic level and this chain is known as the food chain.

so the correct answer is 'Food Chain'.
