Question

food chains and trophic levels quiz (m25)
fill in the food chain using the terms below.
sun -->
tertiary consumer primary consumer producer secondary consumer

Explanation:

Step1: Understand the food chain concept

In a food chain, energy starts from the Sun. Producers (like plants) use sunlight to make food via photosynthesis.

Step2: Identify the first link

The first blank after Sun is filled with "producer" as they are the initial energy - converting organisms.

Step3: Identify the next link

Primary consumers (herbivores) eat producers. So the second blank is "primary consumer".

Step4: Identify the third link

Secondary consumers (carnivores that eat herbivores) come next. So the third blank is "secondary consumer".

Step5: Identify the last link

Tertiary consumers (carnivores that eat secondary consumers) are at the top. So the last blank is "tertiary consumer".

Answer:

Sun --> producer --> primary consumer --> secondary consumer --> tertiary consumer
