Question

which level will contain plants? image of a pyramid with levels a, b, c, d options: a, c, d, b

Explanation:

Step1: Recall Ecological Pyramid

In an ecological pyramid (like a trophic pyramid), the base (lowest level) consists of producers, which are plants (or autotrophs) that make food via photosynthesis.

Step2: Identify the Base Level

The pyramid here has levels D (bottom), C, B, A (top). The bottom level (D) is the base of the pyramid, which in a trophic pyramid holds producers (plants).

Answer:

D (the bottom level, labeled D in the pyramid)
