Question

The table shows the habitat and foraging habits of two fish species in a marine ecosystem.

Fish Species Data
Species Habitat Foraging Habit
A Up to 1,000 meters Large herbivorous fish
B Deeper than 1,000 meters Shrimps

A non-native species that is found at depths of up to 1,000 meters and feeds on small fish was introduced in the ecosystem. What would be the likely impact?
Species A’s population will decrease due to limited space in the ecosystem
Species B’s population will decrease due to limited space in the ecosystem
Population of species A will decrease due to limited prey in the ecosystem
Population of species B will decrease due to limited prey in the ecosystem
