Question

which of the following is a group of autotrophs? wolf, coyote, tiger; grasshopper, wasp, spider; grass, orange tree, algae

Explanation:

Autotrophs are organisms that can produce their own food (e.g., via photosynthesis or chemosynthesis). Grass, orange trees, and algae are autotrophs: grass and orange trees do photosynthesis, algae (many types) also photosynthesize. The other options (wolf, coyote, tiger; grasshopper, wasp, spider) are heterotrophs (consume other organisms).

Answer:

grass, orange tree, algae
