what is the relationship between autotrophs and producers
Autotroph An autotroph ("self-feeding", from the Greek autos "self" and trophe "nourishing") or producer, is an organism that produces complex organic compounds (such as carbohydrates, fats, and proteins) from simple substances present in its surroundings, generally using energy from light (photosynthesis) or inorganic chemical reactions (chemosynthesis).[1] They are the producers in a food chain, such as plants on land or algae in water (in contrast to heterotrophs as consumers of autotrophs). They do not need a living source of energy or organic carbon. Autotrophs can reduce carbon dioxide to make organic compounds for biosynthesis and also create a store of chemical energy. Most autotrophs use water as the reducing agent, but some can use other hydrogen compounds such as hydrogen sulfide. Some autotrophs, such as green plants and algae, are phototrophs, meaning that they convert electromagnetic energy from sunlight into chemical energy in the form of reduced carbon.
Factors of production In economics, factors of production, resources, or inputs are which is used in the production process to produce outputâ€”that is, finished goods and services. The utilized amounts of the various inputs determine the quantity of output according to the relationship is called the production function. There are three basic resources or factors of production: land, labour and capital. The factors are also frequently labelled "producer goods or services" to distinguish them from the goods or services purchased by consumers, which are frequently labeled "consumer goods". All three of these are required in combination at a time to produce a commodity.
