exclusion principle does not always leads to the species exclusion. The
competiting species may co-exist due to different partitioning like temporal
portioning, spatial partitioning, morphological patitioning.Darwin
found fourteen species of finches to co-exist in Galapagos islands due to
development of different feeding habits. Similarly, in Serengeti plains over
20 species of antelopes graze in the same area. Several plants can grow
together by sending their roots to various lengths. Therefore, competition
does not always result in extinction of species but causes development of
larger number of niches |
