Q1) What is algae?

Algae are a diverse group of photosynthetic organisms that belong to the kingdom Protista. They can be found in a variety of aquatic environments, ranging from freshwater to marine habitats, and even in some terrestrial environments. Algae are autotrophic organisms, which means they can produce their own food through photosynthesis. They contain pigments, such as chlorophyll, which enable them to capture sunlight and convert it into chemical energy.
