Answer 2

Hey there!Here's your answer

Algae are plants, so they "eat" much the same things as other plants - CO2, light, and chemical nutrients from their environment. These nutrients include compounds of elements such as phosphorus and nitrogen, which contribute to algal blooms when fertilizer leaches into waterways. Algae are at the very bottom of the food chain for living organisms.
