Question

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.

Answer 1

The correct option is d. Energy stored in plants is transferred to humans and animals that eat them

Step-by-step explanation:

Hello!

We will answer that!

We can divide the ecosystem into different parts: hydrosphere, it is the part that contains water; the atmosphere is the part that is the air; the lithosphere is the part that has the rocks; The biosphere is the earth and where the living beings are.

In the ecosystem, all parts coexist, help each other and connect.

Let's analyze all the options:

Plant roots take in water from the soil: in this option two parts act, the biosphere and the hydrosphere

Plants take in carbon dioxide from the air: in this option two parts act, the biosphere and the atmosphere

During photosynthesis, plants make food and release oxygen into the air: in this option two parts act, the biosphere and the atmosphere

Energy stored in plants is transferred to humans and animals that eat them: in this option they act only a part that is the biosphere

After the analysis, we conclude that the correct option is d. Energy stored in plants is transferred to humans and animals that eat them

Answer 2

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.
