Transcript text: A frog has more offspring than can survive on available resources. Of which is this an example? structural adaptation overpopulation variation in a population artificial selection
Solution
The answer is the second one: overpopulation.
Explanation for each option:
Structural adaptation: This refers to physical features of an organism that enhance its survival or reproduction. The scenario described does not involve any physical changes or adaptations in the frog.
Overpopulation: This occurs when a species produces more offspring than the environment can support with available resources. The scenario directly describes a situation where a frog has more offspring than can survive due to limited resources, which is a classic example of overpopulation.
Variation in a population: This refers to differences among individuals within a species. While variation is important for natural selection, the scenario does not mention differences among the frog offspring.
Artificial selection: This is the process by which humans breed plants and animals for particular genetic traits. The scenario does not involve human intervention or selective breeding.
In summary, the situation described is an example of overpopulation, where the number of offspring exceeds the capacity of the environment to support them.
