NEET BIOLOGY

Detailed explanation-1: -Answer and Explanation: Organisms that obtain their energy by feeding on other organisms are called heterotrophs. Autotrophs are living organisms that are able to make their own food through photosynthesis, and these are plants and algae. Organisms that must consume or absorb their nutrients are called heterotrophs.

Detailed explanation-2: -A heterotroph is an organism that eats other plants or animals for energy and nutrients. The term stems from the Greek words hetero for “other” and trophe for “nourishment.”

Detailed explanation-3: -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-4: -Because most autotrophs transform sunlight to make food, we call the process they use photosynthesis. Only three groups of organisms-plants, algae, and some bacteria-are capable of this life-giving energy transformation. Autotrophs make food for their own use, but they make enough to support other life as well.
