Final answer:
The optimal technique to determine the distribution pattern of a zebras population is the mark and recapture method, which is suitable for studying mobile organisms by marking and later recapturing some individuals to estimate population dynamics.
Step-by-step explanation:
To determine the distribution pattern of a population of zebras, the best measuring technique would be mark and recapture. This method is particularly useful for mobile organisms such as mammals, birds, or fish. It involves marking a sample of captured animals with tags, bands, paint, or other body markings, releasing them back into their environment, and subsequently recapturing some to estimate the population size and distribution pattern.
The risk of no separation as the population will not be thinned out enough typically refers to the fact that if individuals are not efficiently sampled and marked, the subsequent estimates of population size and distribution could be inaccurate.
A clumped population distribution pattern, such as the one which might be determined through this technique, often suggests that organisms group together for various reasons, such as social interactions, access to resources, or environmental factors.
