Question

How was the food chain affected by this species going extinct?

Answer 1

Overall ecosystem instability due to reduced biodiversity ranks among the consequences of species extinctions. As the number of species in a food chain decreases, there are fewer sustainable alternatives for members of the food chain that had depended on the extinct species.

Answer 2

When one of the links (species) in a food chain is no longer present (for example a species goes extinct or a feral animal takes over), the food chain breaks. Sometimes, this can cause other animals in the food chain to disappear as well and the whole ecosystem can become imbalanced or even collapse.
