Why are algae placed in the first place of the food chain?

Algae:

1. Algae refer to photosynthetic aquatic plants that lack a well-defined body structure.
2. They exist in oceans, rivers, lakes, ponds, and even brackish waters.
3. The majority of algae are photoautotrophs and possess pigments such as Chlorophyll A, B, and C.
4. They are primary food producers and form the energy base of the food web.
5. They capture solar energy and generate chemical energy through the process of photosynthesis.
