The correct Answer is:
To solve the question, "If a superior competitor is removed from the area, there is always an increased population of the otherwise exploited species," we need to identify which principle this phenomenon corresponds to among the given options. ### Step-by-Step Solution: 1. **Understanding the Question**: The question describes a scenario where the removal of a superior competitor leads to an increase in the population of a species that was previously being exploited or limited by competition. 2. **Analyzing the Options**: - **Option 1: Principle of Competitive Exclusion**: This principle states that two species competing for the same resources cannot coexist if one is a superior competitor. The superior species will outcompete the other, leading to the exclusion of the inferior species. This does not explain the increase in population of the exploited species after the removal of the superior competitor. - **Option 2: Principle of Resource Partitioning**: This principle refers to how species divide resources to minimize competition. While it explains coexistence, it does not directly relate to the increase in population of an exploited species after the removal of a competitor. - **Option 3: Principle of Competitive Release**: This principle states that when a superior competitor is removed, the previously suppressed or exploited species can thrive and increase in population due to the reduction in competition. This directly aligns with the scenario described in the question. - **Option 4: More than one option is correct**: Since we have identified that only one option (Option 3) is correct, this option is not valid. 3. **Conclusion**: Based on the analysis, the correct answer is **Option 3: Principle of Competitive Release**. This principle accurately describes the phenomenon where the removal of a superior competitor allows the previously exploited species to flourish. ### Final Answer: **Option 3: Principle of Competitive Release**

The relationship between population density (N_(t)) and population growth rate (R = N_(t+1) l N_(t)) in a certain animal species is shown below. Choose from the following graphs the appropriate populations growth patterns that would be obtained if the population is at the densities (I, II, III) shown in the graph above. [Note : THe y-axis in A to D is relative density that cannot be compared to the absolute density in the figure]

A botanist is cultivating a rare species of plant in a controlled environment and currently has 3000 of these plants. The population of this species that the botanist expects to grow next year, N_("next year") , can be estimated from the number of plants this year, N_("this year") , by the equation below. N_("next year")=N_("this year")+0.2(N_("this year"))(1-(N_("this year"))/(K)) The constant K in this formula is the number of plants the environment is able to support. The botanist would like to increase the number of plants that the environment can support so that the population of the species will increase more rapidly. If the botanist’s goal is that the number of plants will increase from 3000 this year to 3360 next year, how many plants must the modified environment support?
