9. Carrying capacity , denoted as k is the maximum number of individual a population can contain.
Human population is reaching its k and is very near from its carrying capacity.The two signs are -
a. Human population is growing day by day and it is very fast.Global climate change , mass extinction , overexploitation of our global commons have altered our natuaral landscape.Our growing population rising with affluences and per capita impact driving our planet to the edge.
b. Our ecological footprints are getting faded.Ecological footprint is a measurement of the anthropogic impact on earth.It tracks how much biocapacity there is and how much biological capacity people use by comparaing the rate at which we consume natural resources and generate waste to the planet's ability to replenish those resources and absorb waste.
Two characteristics of a slow growth rate population are as follows -
a. Low birth rate - Due to good family planning , access to birth control ,financial planning , education etc.
b. Low death rate - Due to good medical care , nutrition , hospitalisation etc.

What type of population growth has the human population experienced over the last 10,000 years? Explain how the human population has grown, and what factors are likely responsible for this growth. What will happen when we reach the carrying capacity for humans? What factors that limit population growth are likely to result in a slow-down of this growth?

1. A population of native beetles with 3,000 individuals has a carrying capacity of 7,500, and a per capita rate of increase of 0.03 per week. Suppose 2,000 individuals of an invasive species are added to the community and that this species has a competitive coefficient of 1.3 on the native species. What is the population growth rate of the native beetle under these conditions? a. 90.6 per week b. 71.3 per week c. 22.8 per week 1.3 per week...

POPULATION MODELS: PLEASE
ANSWSER ASAP: ALL 3 AND WILL RATE U ASAP.
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...
