Exotic pets, such as lizards and tarantulas, have increased in popularity. These animals are caught in the wild and sold as pets. What are two possible effects this action can have on biodiversity?

The two biggest effects are extermination and disruption of the food chain.

The capturing of these animals reduces their numbers in the wild and in time they became scarce and on the verge of extinction.

The disruption of the food chain is another big effect which is caused by removing these animals from the wild. A gap is left by their removal, that causes their pray/food to rise in numbers, while the animals that were praying on them are left with less food which can cause decline in their number.
