Final answer:
The zookeeper will run out of feed for the species with the highest rate of consumption relative to the feed's availability and replenishment frequency. Factors such as diet similarity, consumption rates, and natural selection play a significant role in this outcome.
Step-by-step explanation:
The zookeeper will likely run out of feed for the species that consumes the most food, the fastest, or that has the highest demand relative to its supply. To determine this, you would need to look at factors such as the rate of consumption per species, the amount of feed available, and the frequency at which the feed is replenished.
For example, if species A, B, and C coexist due to similar diets but species A consumes food at a faster rate, the zookeeper will run out of the feed for species A first unless it's replenished more frequently than the others. In scenario F, if two species are the same but one has a better sense of smell for a limited food source, over time, natural selection may favor the one with the better sense of smell, leading to greater survival and reproductive success of that variant.
