What is the food chain for a Tiger?
Nothing eats the tiger – that’s why it’s known as a “top predator” (also called “apex predator”, “alpha predator”, “superpredator” or “top-level predator”). An invertebrate is an animal with no backbone (such as the insect you mentioned). Something that might eat insects might be a bird or perhaps a small mammal such as a shrew or perhaps a frog or toad.
