Question

Describe photo auto trophic nutrition

Answer 1

Answer:

Photoautotroph are organisms that carry out photosynthesis. Using energy from sunlight, carbon dioxide and water are converted into organic materials to be used in cellular functions such as biosynthesis and respiration. In an ecological context, they provide nutrition for all other forms of life (besides other autotrophs such as chemotrophs). In terrestrial environments plants are the predominant variety, while aquatic environments include a range of phototrophic organisms such as algae (e.g. kelp), protists (such as euglena) and bacteria (such as cyanobacteria).

Answer 2

Photoautotrophic mode of nutrition is the process of formation of food by the process of photosynthesis.

In this process, the organism used sunlight as a source of energy along with carbon dioxide and water.

An organism that follows such mode of nutrition is called as photoautotroph e.g., algae, green plants.
