Detailed explanation-1: -Algae, along with plants and some bacteria and fungi, are autotrophs. 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.

Detailed explanation-2: -Most plants are autotrophs because they make their own food by photosynthesis. But for every rule there is an exception. Some plants are non-photosynthetic and parasitic, obtaining their food through a host.

Detailed explanation-3: -Autotrophic – Plants exhibit autotrophic nutrition and are called primary producers. Plants synthesis their food by using light, carbon dioxide and water. Heterotrophic – Both animals and human beings are called heterotrophs, as they depend on plants for their food.

Detailed explanation-4: -Autotrophic Nutrition: Photosynthesis, Chemosynthesis, Examples.

Detailed explanation-5: -Autotrophic nutrition is a process in which the organism produces its food from simple inorganic materials such as water, carbon dioxide and mineral salts in the presence of sunlight. All the green plants have an autotrophic mode of nutrition.
