NEET BIOLOGY

Detailed explanation-1: -Ans-: Cyanobacteria, grass, wheat, seaweed, algae, euglena are examples of autotrophs. Cyanobacteria are prokaryotic organisms. They have a combination of pigments, and they can perform oxygenic photosynthesis. Bacteria are prokaryotic single-celled organisms without a nucleus membrane.

Detailed explanation-2: -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-3: -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.
