Vedclass · Answer

(A) Fungi are heterotrophic organisms because they cannot synthesize their own food through photosynthesis.This is primarily because they lack chlorophyll,the pigment required to capture light energy for the production of organic compounds.Since they lack chlorophyll,they must obtain nutrients from external organic sources,which defines the heterotrophic mode of nutrition.Therefore,the absence of chlorophyll $(R)$ is the direct reason why fungi exhibit heterotrophic nutrition $(S)$.
