If the carrying capacity of the lake drops from 150 to 100 minnows, the minnow population will decrease to around 100 minnows. This will happen because there will not be enough resources to support the larger population.
If the carrying capacity of the lake drops from 150 to 100 minnows, the minnow population will decrease to around 100 minnows. This will happen because there will not be enough resources to support the larger population.
Minnow populations are regulated by a number of factors, including the availability of food, space, and predators. When the carrying capacity of a lake decreases, it means that there is less of one or more of these resources available. This can happen due to a number of reasons, such as pollution, drought, or the introduction of a new predator species.
When the carrying capacity of a lake decreases, the minnow population will initially exceed the carrying capacity. This is because the minnows will continue to reproduce at their normal rate, even though there are fewer resources available. However, the minnow population cannot remain above the carrying capacity for long. Eventually, the lack of resources will lead to increased competition among the minnows, and some of the minnows will die. This process will continue until the minnow population reaches the new carrying capacity.
In the scenario described in the image, the minnow population will decrease from 140 minnows to around 100 minnows. This is because the carrying capacity of the lake has decreased from 150 minnows to 100 minnows. The minnow population will decrease through a combination of competition and death.
It is important to note that the exact rate at which the minnow population will decrease will depend on a number of factors, such as the severity of the decrease in carrying capacity and the resilience of the minnow population. However, in general, the minnow population will decrease until it reaches the new carrying capacity.
