Answer:
Step-by-step explanation:
The effect of excessive increase in the number of frogs in the pond ecosystem on the flies is a decrease because the frogs will eat more with It being a larger population.
What is Population?
This is referred to as the total number of organisms in a given area over a period of time and it is dependent on various factors such as the availability of food, water, etc.
In the ecosystem, we have different types of consumers and in this scenario, the fly is the primary consumer and the frog is the secondary consumer.
The frog eats the flies for survival as it acts as its predator and we were told that there was an increase in the number of frogs in the pond ecosystem which means that there will be a great reduction in the flies as they need it for their survival.
