HORTICULTURE

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: -These are the organisms that can prepare their own food from simple substances like carbon dioxide and water. All green plants are examples of autotrophs.

Detailed explanation-3: -Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.

Detailed explanation-4: -In the process of photosynthesis, autotrophs convert carbon dioxide and water into sugar and oxygen. The major advantage of photosynthesis is primarily the production of oxygen by autotrophs, by fixing carbon dioxide into the cells. The process also produces glucose, which is an important food source.

Detailed explanation-5: -Pitcher plant has both autotrophic and heterotrophic mode of nutrition.
