Answer 1

Answer:

A. ii only

• Tertiary carnivores (or quaternary consumers) occupy the fourth trophic level, preying on secondary carnivores.

• Apex predators, or top carnivores, sit at the very top of the food chain, meaning they have no natural predators in their ecosystem.

• Animals like lions and tigers, for example, typically prey on large herbivores (primary consumers) and sometimes smaller carnivores (primary or secondary carnivores), rather than exclusively primary carnivores.

• Their role is crucial in regulating populations lower down the food web.
