None by definition, a population can never exceed its carrying capacity.
The carrying capacity of a population is tha maximum population size of the species that the environment can sustain.
Hence the growth can never increase above its carrying capacity.

The logistic growth model describes population growth when
resources are constrained. It
is an extension to the exponential growth model that includes an
additional term introducing
the carrying capacity of the habitat.
The differential equation for this model is:
dP/dt=kP(t)(1-P(t)/M)
Where P(t) is the population (or population density) at time t,
k > 0 is a growth constant,
and M is the carrying capacity of the habitat. This...

A) A population undergoing logistic growth should reach it's maximum growth rate when... the population is equal to the carying capacity. the population size is very small but not quite zero. the population size is farthest from the carying capacity. the population is half of the carying capacity. the carying capacity is changing rapidly. B) Trophic efficiency is the percentage of production transferred from photosynthesis to any higher trophic level. a measure of how nutrients are cycled from one trophic...
Which pattern of survivorship is most likely for an organism such as the penguin, which produces only a single offspring at a time,
7. Which pattern of survivorship is most likely for an organism such as the penguin, which produces only a single offspring at a time, provides a lot of parental care and has a relatively long lifespan? Most offspring survive for most of their potential life span and then die at approximately the same time. The probability of death due to natural causes is high throughout the life span. Survivorship is low early in life and then levels off. Young individuals have a...

3. The graph below has axes to show the population sizes of a predator and its prey. The dashed lines are the predator and prey isoclines. Prey Population Starting at the circle, draw in what will happen to the two populations if they are following the pattern in the Lotka-Volterra model of predation. (Remember that BOTH predator and prey numbers are represented by a point on the graph.) Use a series of arrows to show what happens. 2. Imagine two...
