Vedclass · Answer

(D) Population attributes are characteristics that change over time due to various factors.$1$. Population size (or density) is not a static parameter; it fluctuates due to changes in birth rates,death rates,immigration,and emigration.$2$. Predation rate is also not constant as it depends on the availability of prey and the density of predators,which vary over time.$3$. Growth rate is a derived parameter that depends on the aforementioned factors and is also dynamic.Since both population size and predation rate are dynamic and not constant,the correct answer is $D$.
