(Ho) by which the class would judge whether or not one of the other two
scenarios happened. Another scenario, which was not tested for, could have
been instability—that is, two species are in a constant state of dynamic
tension where at one time one species dominates and at other times the other
species dominates. Different species of plants are able to coexist within the
same biome through resource partitioning, which functions through the
evolution of different metabolic pathways, having different tolerances to
shade, taking up water and nutrients at different depths, etc.Question 3

(a) 4 points maximum Compare and contrast the two age-structure diagrams in
terms of two population dynamics—birth rate and death rate.
Age-structure diagrams are basically divided into three major age categories: ■
Pre-reproductive (0–15 years old)
■ Reproductive (16–45 years old)
■ Post-reproductive (46 years old–death)
