Calculate the rate of population change for a hypothetical population of wildebeest using the logistics equation and carrying capacity equation. How can you explain these results?
N = 500, r = 0.1, K = 1000, calculate dN/dt.
Why is figure b dome-shaped / n-shaped?
In populations of unitary organisms, growth rates and rates of development are generally influenced by intraspecific competition. This essentially leads to density-dependent effects on the composition of a population.
1) Explain/discuss figure b (limpets)
2) Explain/discuss figure a (reindeers)

This simulation assumes one prey species and one predator species in an imaginary ecosystem and is based on mathematical equations.
