NEET BIOLOGY

Detailed explanation-1: -Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color.

Detailed explanation-2: -They use energy from the sun to convert carbon dioxide and water into glucose, as well as oxygen as a byproduct. This process, which is unique to plants, is photosynthesis.

Detailed explanation-3: -The food chain begins with the sun: plants get their energy by photosynthesizing sunlight into energy, and then herbivores eat those plants to get their energy. Carnivores who then eat the herbivores are getting that sunlight passed along from sun to plant to herbivore to carnivore.

Detailed explanation-4: -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-5: -Majority of the members of kingdom Plantae possess chlorophyll pigment indifferent parts of their body which makes them capable of synthesising their own food by the process of photosynthesis. This mode of nutrition is known as autotrophic mode of nutrition and makes plants the major producers of food in an ecosystem.
