Here's how it works:
* Producers: At the bottom of the food chain are producers, like plants, which make their own food through photosynthesis.
* Primary Consumers: Herbivores, like rabbits, eat the producers.
* Secondary Consumers: Carnivores, like foxes, eat the herbivores.
* Tertiary Consumers: Larger carnivores, like wolves, might eat the foxes.
* Apex Predators: At the top of the food chain are apex predators, like sharks or lions, which have few or no natural predators.
The bigger fish eating the smaller fish is an example of a food chain where larger predators consume smaller prey. This is a common pattern in many ecosystems.
