Algae
Definition
Algae are diverse groups of photosynthetic organisms that range from single-celled microalgae to large seaweeds. They play crucial roles in aquatic ecosystems as primary producers and serve as a food source for many organisms.
Analogy
Picture algae as tiny green factories floating around in water. Just like factories produce goods for people to consume, algae produce energy-rich compounds through photosynthesis that other organisms rely on.
