NEET BIOLOGY

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: -Only certain organisms, called autotrophs, can perform photosynthesis; they require the presence of chlorophyll, a specialized pigment that can absorb light and convert light energy into chemical energy.

Detailed explanation-3: -All green plants synthesizing their own food through the biological process called Photosynthesis are examples of Autotrophs.

Detailed explanation-4: -A major difference between autotrophs and heterotrophs is that the former are able to make their own food by photosynthesis whereas the latter cannot.
