Question

other organisms to obtain nourishment and energy, occupying various trophic levels within ecosystems. chemotrophs, adapted to extreme environments like deep - sea vents, derive their sustenance from chemical compounds. a lion primarily eats other animals for energy. what kind of organism does this make the lion? chemotroph heterotroph autotroph

Explanation:

Heterotrophs obtain energy by consuming other organisms. Since the lion eats other animals for energy, it fits the definition of a heterotroph. Chemotrophs derive energy from chemical compounds (not other organisms), and autotrophs produce their own energy (e.g., through photosynthesis), which doesn't apply to the lion.

Answer:

heterotroph
