Ok oh my god i’ve been searching similar spieces that are found together for the past 4 hours!! At first I did lions and tigers but lions live in africa and tigers live in asia therefore they are not often found together. I need two species that usially compete for food and if possible in the same “family”. Like pigeons and sparrows are from the “bird family” Ok plzz help with these questions:
Choose two similar species that are often found together (like pigeons and sparrows).
Find three locations where both species live.
Hypothesize how the features of each location affect the population of each species.
Is there evidence of competitive exclusion or niche differences? Explain.
Thanks

Similar selection pressures lead to similar features the evolve in related species (7)
Reproductive isolating mechanism that occurs before fertilization (10)
Speciation that occurs abruptly (13)
Small population rapidly diverges to occupy new niches in adaptive radiation (13)
