    d. autotrophs: "Autotrophs are the producers in a food chain, such as plants on land or algae in water." so pretty much they produce their own food.

    Capture sunlight to produce sugars. Autotroph means it feeds itself. (Auto + troph..means something like feeding? food?) Algae make food for themselves, out of themselves, using photosynthesis, being plants and all.
