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

21. A biologist places a single, living sponge in a saltwater tank. After several weeks, the biologist observes other small sponges living in the tank. Because the biologist is certain that no other sponge was introduced into the tank, what other explanation could you provide to explain the observation?
22. Describe the body of a leech. In what way do the leech’s adaptations make it suited for its niche?
23. Segmented tube worms that live near the vents grow to lengths of 1.5 m in contrast to the growth of related tube worms living in other environments, whose growth is measured only in centimeters at most. You hypothesize that the food that the worms eat is more abundant at the vents. When you collect samples of the worms, you discover that they have no mouth or other means of taking in food. Hypothesize how the tube worms are obtaining nutrients.
