Options:

Correct Answer: Food chain

Exam Year: 2020

Solution:

The food chain illustrates how energy is transferred from one trophic level to another in an ecosystem.

What is the process by which energy is transferred from one trophic level to another? (2020)

What is the process by which energy is transferred from one trophic level to another? (2020)

Step 1: Understand what a trophic level is. Trophic levels are the different stages in a food chain, such as producers, primary consumers, and secondary consumers.
Step 2: Identify the first trophic level, which is made up of producers (like plants) that create energy through photosynthesis.
Step 3: Recognize that the energy from producers is transferred to the next level, which includes primary consumers (like herbivores) that eat the plants.
Step 4: Understand that when primary consumers eat the producers, they gain energy from them.
Step 5: Identify the next trophic level, which includes secondary consumers (like carnivores) that eat the primary consumers.
Step 6: Realize that energy continues to transfer from primary consumers to secondary consumers when they eat them.
Step 7: Note that energy transfer is not 100% efficient; some energy is lost as heat at each level.
Step 8: Conclude that the food chain shows how energy moves from one trophic level to another in an ecosystem.
