The figure below depicts life-histroy strategies for three plant species (a,b and c) along 3 axes : strength of competition with other organisms, level of distrubance in the habitat, and level of environmental stress in the habitat. Species a grows in habitats where competition among species b grown in habitats with and stress are low. Species b grows in habitats with high environmental stress but with low interspecies competition. Species c grows in highly disturbed habitats with low enviornmental stress.
Which of the statements below is/are correct ?
I. Characteristics of "a-type" plants are faster growth rate and short-lived leaves.
II. Desert annual plants are "b-type" species. they have rapid growth and produce large amount of seeds in a short time after rains.
III. Most plants belonging to "c-type" species would be herbaceous while "a-type" and "b-types" species are likely to be trees or shrubs.
