Detailed explanation-1: -Autotrophs are the producers in the food chain, meaning they create their own nutrients and energy. Kelp, like most autotrophs, creates energy through a process called photosynthesis. An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals.

Detailed explanation-2: -All organisms carrying out photosynthesis require sunlight. Heterotrophs are organisms incapable of photosynthesis that must therefore obtain energy and carbon from food by consuming other organisms.

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. Dogs, birds, fish, and humans are all examples of heterotrophs.

Detailed explanation-4: -Autotrophic nutrition is a process by which autotrophs take in substances from outside and convert them into stored forms of energy. Plants absorb the carbon dioxide and water from the outside and convert them into carbohydrates in the presence of sunlight and chlorophyll. This process is called photosynthesis.

Detailed explanation-5: -“Autotrophic nutrition is a process where an organism prepares its own food from a simple inorganic material like water, mineral salts and carbon dioxide in the presence of sunlight.” The term “autotrophic” is formed by the combination of two terms, “auto” meaning self, and “trophic” meaning nutrition.
