Human lung tissue * A heterotroph (heteros = "another"‚ "different" and trophe = "nutrition") is an organism that cannot fix carbon and uses organic carbon for growth * An autotroph[α] ("self-feeding"‚ from the Greek autos "self" and trophe "nourishing") or "producer"‚ is an organism that produces complex organic compounds (such as carbohydrates‚ fats

water from the soil to produce food - in the form of glucose/sugar. These are also known as autotrophs‚ since they make their own food. Producers are able to harness the energy of the sun to make food. The process is called photosynthesis. * Consumers Consume means “eat” Animals are consumer because they eat (consume) food provided by plants and other animals. They also called Heterotrophs because animals cannot make their own food so they must eat plants and/or other animals. In short

all the nitrogen found in the atmosphere‚ such form of nitrogen created by the bacteria is useful for plants to use again. 2. What are producers? Producers are organisms that are able to create their own food through photosynthesis. They are autotrophs (green plants) that are located in the lowest part of the energy pyramid‚ and provide the source of energy for all the other organisms. 3. What type of organisms are decomposers? Decomposers are organisms that break down dead animals‚ plants
