Please help me with these ungraded practice problems. I am a bit confused.
Draw the plots using google sheets or excel and please include pictures of the plots and directions on how you plotted it. Equation 3 and 4 are attached as images.
Equation (3) is density independent because the population growth that takes place between time t and time t +1 does not depend on the population density N. That is, it is density independent because there is no N term on the right hand side of Equation (3).
In contrast, one possible discrete time mathematical model that includes density dependence (equation 4) is
where K is the carrying capacity (expressed in units of population density). Note that when Nt= K, the whole term in the exponent equals zero. Since e0 = 1, this means that the ratio
Nt+1/Nt does not change from one year to the next when Nt = K.
1a) Draw a plot of the ratio of population densities in Eq. (3) as a function of N if you set if r = 0.05.
1b) Draw a plot of the ratio of…

- Background A trophic level, or feeding level, is made up of all the organisms whose energy source is the same number of consumption steps from the sun in a given ecosystem. The trophic level of plants or producers is 1, while that of herbivores is 2 and that of animals that eat herbivores 3. Higher trophic levels can exist for animals even higher on the food chain. In this exercise, you will compute numerical values for human energy needs based on diets at different trophic levels. In this case study the owner of a farm raises soybeans and chickens. Grasshoppers feed on the farmers soybeans, and are in turn eaten by the chickens. Humans can, though rarely do, eat grasshoppers for sustenance. Humans can also eat soybeans. For the purpose of this exercise, make the following assumptions: A human requires 1 chicken/day There are 365 days/year 1 chicken eats 25 grasshoppers/day 1 grasshopper requires about 30 g of soybeans/year 1,000 grasshoppers have a mass of 1 kg 1 human requires…arrow_forwardBackground A trophic level, or feeding level, is made up of all the organisms whose energy source is the same number of consumption steps from the sun in a given ecosystem.
