Which interaction involves only  one  of earth’s spheres? plant roots take in water from the soil. plants take in carbon dioxide from the air. during photosynthesis, plants make food and release oxygen into the air. energy stored in plants is transferred to humans and animals that eat them.

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.
