Detailed explanation-1: -Which BEST describes why autotrophs begin every food chain? They are the only trophic level that can use the sun’s energy to create glucose. They get their nutrients from detritivores and decomposers. They can reproduce faster than consumers.
Detailed explanation-2: -Plants are autotrophs and convert the solar energy into food by photosynthesis hence they form the first trophic level of a food chain. They are consumed by primary producers that are the herbivores.
Detailed explanation-3: -Autotrophs are known as producers because they are able to make their own food from raw materials and energy. Examples include plants, algae, and some types of bacteria. Heterotrophs are known as consumers because they consume producers or other consumers.
Detailed explanation-4: -Producers, also known as autotrophs, make their own food. They make up the first level of every food chain. Autotrophs are usually plants or one-celled organisms. Nearly all autotrophs use a process called photosynthesis to create “food” (a nutrient called glucose) from sunlight, carbon dioxide, and water.
Detailed explanation-5: -Producers make up the first trophic level. Producers, also known as autotrophs, make their own food and do not depend on any other organism for nutrition. Most autotrophs use a process called photosynthesis to create food (a nutrient called glucose) from sunlight, carbon dioxide, and water.
