Which one of the following organisms is dependent on saprophytic mode of nutrition?
Agaricus
This question asks us to identify which organism among the given options relies on a saprophytic mode of nutrition. Let's explore the nutritional strategies of each organism listed.
Saprophytic nutrition is a process where an organism obtains nutrients from dead or decaying organic matter. These organisms, known as saprophytes, secrete digestive enzymes onto the dead material, breaking it down externally. They then absorb the simpler, digested molecules. Fungi and some bacteria commonly exhibit this mode of nutrition, playing a crucial role as decomposers in ecosystems.
We need to determine the mode of nutrition for each option provided:
\[ 6CO_2 + 6H_2O \xrightarrow{\text{Light Energy}} C_6H_{12}O_6 + 6O_2 \]
Based on the analysis of their nutritional modes:
Therefore, the only organism listed that is dependent on a saprophytic mode of nutrition is Agaricus.
