A research team is studying the population dynamics of two interacting species, species A and species B, in a controlled environment. The population of species A, denoted by $A(t)$, is influenced by a seasonal resource availability and the presence of species B. The population of species B, denoted by $B(t)$, is affected by the population of species A as a food source and also experiences exponential decay due to natural attrition.
b. The population of species B is modelled by the function $B(t) = 200e^{-0.02t} + 0.2A(t)$, where $t$ is measured in months. After a very long time (as $t$ approaches infinity), the population of species A stabilises at approximately 480. Evaluate and interpret the long-term behaviour of the population of species B.
