NEET BIOLOGY

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: -Autotrophs rely on either light or chemical energy to turn CO2 into organic carbon molecules. Photoautotrophs are photosynthesizing organisms such as algae and higher plants that use light for this process. Heterotrophs, in contrast, obtain their chemical energy from preexisting organic molecules.

Detailed explanation-3: -Another name for an autotroph is autophyte. It can also be called a producer for its capacity to produce its own food. Examples are shown in the autotroph picture below. Plants, lichens, and algae are examples of autotrophs capable of photosynthesis.

Detailed explanation-4: -Photosynthetic autotrophs capture light energy from the sun and absorb carbon dioxide and water from their environment. Using the light energy, they combine the reactants to produce glucose and oxygen, which is a waste product.

Detailed explanation-5: -There are two types of autotrophs: photoautotrophs and chemoautotrophs.
