Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which interaction involves only one of Earth’s spheres?
A
Plant roots take in water from the soil.
B
Plants take in carbon dioxide from the air.
C
During photosynthesis, plants make food and release oxygen into the air.
D
Energy stored in plants is transferred to humans and animals that eat them.
Explanation: 

Detailed explanation-1: -During photosynthesis, plant roots take in water from soil. During photosynthesis, plants take in carbon dioxide from the air. Through photosynthesis, energy stored in plants is released into the air. Through photosynthesis, energy stored in plants is transferred to humans who eat them.

Detailed explanation-2: -When humans or animals (biosphere) eat the plants, they acquire the energy originally captured by the plants. The biosphere contains all the planet’s living things. This sphere includes all of the microorganisms, plants, and animals of Earth.

Detailed explanation-3: -All the spheres interact with other spheres. For example, rain (hydrosphere) falls from clouds in the atmosphere to the lithosphere and forms streams and rivers that provide drinking water for wildlife and humans as well as water for plant growth (biosphere).

Detailed explanation-4: -Answer and Explanation: Photosynthesis occurs in the cells of plants, bacteria and protists in the biosphere and geosphere. The geosphere is the solid components of the earth’s crust. Photosynthesis is a biological process in which light energy from the sun is used to create sugars from carbon dioxide and water.

Detailed explanation-5: -Energy from the Sun is the driver of many Earth System processes. This energy flows into the Atmosphere and heats this system up It also heats up the Hydrosphere and the land surface of the Geosphere, and fuels many processes in the Biosphere.
