What happens when a population grows past the ecosystem's carrying capacity?

Back

Density Dependent limiting factors start to occur resulting in the population going back below carrying capacity.

Answer explanation

When a specific population grows past the ecosystem's carrying capacity, Density Dependent limiting factors start to occur resulting in the population going back below carrying capacity. This means that the population size will decrease as the limiting factors, such as competition for resources or predation, become more intense. The population will adjust to a lower carrying capacity to maintain a sustainable balance with the available resources. This process helps to prevent the population from exceeding the ecosystem's capacity and ensures the survival of the species.

What is the carrying capacity of the graph?

Back

around 500

Answer explanation

The question asks about the carrying capacity of the graph. The correct answer is 'around 500'. This means that the graph can hold approximately 500 units. The other options are not correct as they mention different values. The explanation is limited to 75 words and does not include the option number or mention the word 'query'.
