Detailed explanation-1: -An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers.

Detailed explanation-2: -The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O2) and chemical energy stored in glucose (a sugar). Herbivores then obtain this energy by eating plants, and carnivores obtain it by eating herbivores.

Detailed explanation-3: -Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs.

Detailed explanation-4: -Plants make their food using a process called photosynthesis, which means “putting together through light.” During photosynthesis, a plant traps energy from sunlight with its leaves. It also takes up water from its roots and carbon dioxide gas from the air.

Detailed explanation-5: -Definition: A producer is someone who creates and supplies goods or services. Producers combine labor and capital-called factor inputs-to create-that is, to output-something else. Business firms are the main examples of producers and are usually what economists have in mind when talking about producers.
