Answer: b. They are composed of molecules that contain carbon-carbon bonds.
c. They undergo chemical reactions to use energy they acquire from the environment.
Living things includes all the organisms that display features which make them distinct from non-living organisms. The living organisms have an organized structure, they are composed of cells, they require energy to survive or sustain existence, they are able to reproduce and they exhibit ability to grow.
They are composed of molecules that contain carbon-carbon bonds: Carbon is the main component present in all living things. They make up the organic biomass of these living organisms.
They undergo chemical reactions to use energy they acquire from the environment: The plants traps sunlight energy and converts it into food and lastly into chemical energy in the form of ATP. This ATP is used as a energy reservoir for metabolic processes occurring in the plants. Therefore, energy is generated after chemical reactions.
Answer: The sun sustains all life on earth through photosynthesis, the process by which plants and other organisms convert the energy of sunlight into chemical energy, stored in the bonds of organic molecules. A central challenge of modern science is to replicate this process using synthetic catalysts, and thus produce solar fuels by artificial photosynthesis.
