the species interbred with each other.
the species were not closely related.
the species had separate niches.
the species lived in different forest types.
Homework Answers
Dear Student,
Robert MacArthur observed the behaviour of five different species of warbler in order to understand how the ecological rule of competitive exclusion was being held despite the presence of very similar warblers sharing similar behaviour. The rule of competitive exclusion states that two species with the same niche cannot exist because one will always out power and displace the other.
In his observation, he found that the five species had different niche. They had different feeding times and different locations of nesting. Hence, the law of competitive exclusion holds true as all the species had different niche.
Therefore, the right answer would be the species had seperate niches.
Thank you!
Please leave a thumbs up.

Enzyme inhibition case study, Part I It was about 50 minutes into another long, boring two-hour lecture by Dr. Foster. The tall, thin, gray- haired biochemistry professor was concluding a chapter on enzymes. The final topic was enzyme inhibition. Sarah, an energetic and outgoing junior, was daydreaming about her upcoming weekend at home for a family reunion. She was not really paying attention, but heard the professor going on and on about alcohol dehydrogenase. At last, Dr. Foster turned to...
