To give a sensible answer to this we will need to know more about the real question or what you have been doing in class.

The Komododragons who appear to have no predators could have a rate of change of population determined by a logistic model:

where is the population growth rate coefficient for small populations and is the carrying capacity of the island when there is a static population of dear .

Then the eqivalent equation for dear might be:

where the extra term represents the predation rate due to the Komodo dragon population.

You will also get a similar equation for the Plant population.
