A trophic pyramid is a visual representation of the trophic levels in an ecosystem, with the producers at the base of the pyramid and the tertiary consumers at the top.
The pyramid would look as follows:
This means that they would match as follows:
• Producers, - Bottom of the pyramid ,(E),
• Primary Consumers, - Second level from the bottom (A)
• Secondary Consumers - Middle of the pyramid (C)
,
• Tertiary Consumers - Second level from the top (D)
,
• Apex Predator - Top of the pyramid (B)
