Final answer:
Energy from the sun is important because biomass sources rely on it for their energy, it powers plant growth through photosynthesis, and it is crucial to use it responsibly as it is not an abundant resource.
Step-by-step explanation:
Energy from the sun is so important for several reasons:
- Biomass sources receive their energy from the sun while living: Plants, algae, and cyanobacteria capture solar energy through photosynthesis and convert it into chemical energy. This energy is transferred to other living organisms when they consume these plants or organisms that got their energy from plants.
- It provides the energy used by plants to make food: Through photosynthesis, plants use sunlight to convert water and carbon dioxide into glucose, which is the primary source of energy for plant growth and development.
- It is not an abundant resource, so it is important to use what we have : The sun provides an almost unlimited amount of energy, but it is important to use it efficiently and conserve it for future generations.
A) Biomass sources receive their energy from the sun while living.
B) It provides the energy used by plants to make food.
Step-by-step explanation:
A) Biomass sources, such as plants, derive their energy indirectly from the sun through photosynthesis. During this process, plants capture solar energy and convert it into chemical energy, which is stored in their tissues.
B) Photosynthesis is the process by which plants convert solar energy into chemical energy in the form of glucose. This energy is used by plants for growth and metabolism and forms the basis of the food chain as other organisms consume plants or organisms that have consumed plants.
C) Uranium does not get its energy directly from the sun. Uranium is a radioactive element, and its energy comes from the process of nuclear fission, not solar radiation.
D) The statement "It is not an abundant resource, so it is important to use what we have" is incorrect. Solar energy is considered an abundant and renewable resource. It is crucial to harness and utilize solar energy sustainably, as it is a virtually limitless source compared to finite resources like fossil fuels.
