When ants are removed their preys population will get bigger.
Polyploidy (more than two complete sets of chromosomes) is not rare among plants. For example, pollen grains may reach female flowers via animals or wind. In some cases, pollen grains from species with 4 complete sets of chromosomes will have 2 sets of chromosomes. Pollen grains may fuse with a female reproductive organ with 1 set of chromosome (so, female plant must have 2 sets of chromosomes). The resulting zygote will have 2 + 1 sets of chromosomes, so the plant will have 3 complete sets of chromosomes.
The extinct animal is most similar to the bottom left due to the spinal similarities. The spine does not demonstrate a sigmoidal curve like the bottom right does. Answer would be bottom left.
