Which of the Following Tends to Predominate in Land Ecosystems

Question

Which of the following tends to predominate in land ecosystems?  
A) Grazing food web
B) Primary production
C) Food web
D) Detrital food webs
E) Biomass pyramid

Accepted Answer

Detrital food webs tend to predominate in land ecosystems because they involve the decomposition of organic matter, which is an important process for nutrient cycling and soil formation. Grazing food webs, primary production, and food webs also have important roles in land ecosystems, but detrital food webs are often the foundation of these systems. Biomass pyramids can vary between ecosystems and are influenced by factors such as climate, productivity, and trophic interactions.
