Question

energy level
trophic level
primary consumers
secondary consumers
decomposers
producers
tertiary consumers
100%
10%
1%
0.1%

Explanation:

Step1: Identify energy level and trophic level

Energy level decreases from bottom to top. Producers (bottom) have highest energy (100%), then primary consumers (10%), secondary consumers (1%), tertiary consumers (0.1%). Trophic levels: producers (base), primary consumers (next), secondary consumers (middle - upper), tertiary consumers (top).

Step2: Match labels

For energy level (left blanks):

• Bottom energy level (with producers in trophic sense) is 100%
• Middle energy level (primary consumers trophic) is 10%
• Top energy level (secondary or tertiary? But looking at pyramid structure, tertiary is top. Since in energy transfer, each level is 10% of previous. Producers (100%) → primary (10%) → secondary (1%) → tertiary (0.1%). So top energy level is 0.1%

For trophic level (right blanks):

• Bottom trophic level (producers)
• Middle trophic level (primary consumers)
• Top trophic level (tertiary consumers)

Answer:

Energy level (from bottom to top): 100%, 10%, 0.1%
Trophic level (from bottom to top): Producers, Primary Consumers, Tertiary Consumers
