Questions. 1920 (A) Interspecific competition (B) Intraspecific competition (C) Predation (D) Parasitism (E) Commensalism 19. Young barnacles (Bolanus balneider) undercut, displace, and overgrow each other during the first year of colonization on a new site. 20. When they we grown separately, the sequence of intrinsic growth rates in several species of duckweed (Lena) is L minor > L narans > L ibba > L polyrhia When they we grown together in various combinations, the sequence becomes L natans > L polyrrhisa > L gibba > L minor.

Answer 1

19 Intraspecific competition. * Intraspecific competition is an interaction in population ecology, where by members of the same species compete for limited resources. This leads to a reduction in fitness for both individuals, however, the most fit individual survives and is able to reproduce (20) Interspecific Competition It is a competition in which individuals of different species compete for the same resources in an ecosystem competition between members of the species Same is called Intra specific Competition
