Question

19/23
which type of organisms are found on base of the ecological pyramids?
omnivores
decomposers
herbivores
autotrophs

Explanation:

Ecological pyramids represent trophic levels. The base consists of producers (autotrophs) as they convert energy (e.g., sunlight) into organic matter, forming the foundation for other trophic levels. Omnivores eat both plants/animals, decomposers break down organic matter, and herbivores eat plants—none form the base like autotrophs.

Answer:

D. autotrophs
