Answer: Energy stored in plants is transferred to humans and animals that eat them.
Biosphere is a sphere on earth where living organism forms a biotic community. It is the sum of all the ecosystems. Various life processes occurring in a biosphere are dependent on other spheres on earth that are lithosphere (rocks), hydrosphere (water) and atmosphere (air). In biosphere living beings interact and fulfill their energy requirements.
Energy stored in plants is transferred to humans and animals that eat them here only biosphere is involved. As, energy produced by plants which is a living component of the ecosystem through photosynthesis is transferred to other living components of the ecosystem that are humans and animals. Therefore, only one sphere is involved in this process.
the answer is a because if the model is based on experimental data it wont be good unless it has been tested.

Plant cells are surrounded by a tough extracellular matrix in the form of a cell wall, which is responsible for many of the unique features of a plant's life style. The cell wall is composed of a network of cellulose microfibrils and cross-linking glycans embedded in a highly cross-linked matrix of pectin polysaccharides. In secondary cell walls, lignin may be deposited. A cortical array of microtubules can determine the orientation of newly deposited cellulose microfibrils, which in turn determines directional cell expansion and therefore the final shape of the cell and, ultimately, of the plant as a whole.
