Herbivores like gazelles are the prey for dangerous predator species like a group of lions and a group of hyenas. Both of these groups are carnivorous predators and can compete to get the prey to themselves in order to satiate their hunger and survive. This is an example of competition population interaction. Stonefish adapts itself to the rocks of the ocean and camouflages with them in order to not get seen by bigger predator fishes like sharks. It also does this while hunting smaller fish as they would not be able to differentiate between the stonefish and its surroundings and fall prey to it. This is an example of camouflage population interaction.
