A and C E. B and C one of the above. Solution Temporal pattern of distribution of species influence the population structure in given environment. Variability in temporal structure in a given environment affects the establishment of the population. The examples of temporal structure in biological community include species existence in a time bound pattern. In deserts, many insects, forbs, and grasses are only seen in the days following a large rainfall and Understory flowers, such as Trillium and Mayapple flower in early spring, before forest trees leaf out and shade them are the examples of temporal structure in biological community. Option D is correct..
