bubble survivorship lab analysis questions directions: post an image of your graph and answer the questions that follow. note that this portion of the lab is independent. lab graph insert an image of your completed graph here how was the shape of the curves influenced by the conditions of each population? in the lab, the bubbles are used to represent the offspring population of a specific organism and recording the lifespan of those bubbles, as a way of simulating the lifespan of organisms when placed under specific conditions. the lab represented 3 different populations, with dissimilar conditions to simulate changes in the populations of organisms in an ecosystem. in the first population, examine the survivorship curves for the soap bubble populations. how do they correlate with the type i, ii, and iii survivorship curves? explain. do any of the bubble populations show a constant death rate for at least part of their lifespan? if so, which? which population represents an r-selected species? a k-selected species? explain your reasoning. identify 2 examples of species that demonstrate the reproductive strategy simulated with population 1: population 2: population 3: population 3 could have been called the bottleneck population, because they were forced to cross the line in order to survive. in nature, what are some situations that would create a type of population bottleneck? would you expect a population in which most members survive for a very long time to produce few or many offspring? which reproductive strategy would be most advantageous to this population over time? explain your reasoning. suppose a human population exhibited a type iii survivorship curve. what would you expect to happen to the shape of the curve if a dramatic improvement in medical technology took place? explain your reasoning.
