This will impact the population of cricket frogs over time due to decreases because the number of predators increases. Hence the correct option is 1.
The population dynamics depicted in the graph, with a slanting downward trend for mosquitoes (prey) and a straight broken line for alligators (predators), suggests an ecological relationship that can influence the population of cricket frogs. As the number of alligators, the predators, increases, it is likely to exert predation pressure on the mosquito population. Since mosquitoes are considered prey for alligators, a rise in the predator population often leads to a decrease in the prey population.
This ecological interdependence could negatively impact cricket frogs, as a reduction in their prey base (mosquitoes) may result in a decrease in the cricket frog population over time. Therefore, the trend in the graph implies a potential cascading effect on the cricket frog population due to changes in the populations of their prey and predators within the pond ecosystem. Hence the correct option is 1.
