Statement 1 (S1) : In terrestrial ecosystem, maximum energy is present in T1.

Statement 2 (S2) : GFC and DFC are not interconnected.

 

In terrestrial ecosystem, maximum energy is present in T1. Plants comprise the first trophic level.

GFC and DFC are interconnected. Detritus food chain may be connected with the grazing food chain at some levels: some of the organisms of DFC are prey to the GFC animals, and in a natural ecosystem, some animals like cockroaches, crows, etc., are omnivores.
