Population Dynamics
Biology ⇒ Ecology and Environment
Population Dynamics starts at 8 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Population Dynamics.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 9
A population of 1000 fish has a birth rate of 100 per year and a death rate of 80 per year. What is the annual population growth?
A population of 200 birds has 40 births and 10 deaths in a year. What is the net change in population size?
A population of 300 animals has a carrying capacity of 500. If the population grows by 50 animals per year, how many years will it take to reach carrying capacity?
A population of deer in a forest is 500. If 50 deer emigrate and 30 immigrate, what is the new population size?
A population of insects doubles every month. If there are 50 insects in January, how many will there be in March?
A population of rabbits increases from 100 to 150 in one year. What is the growth rate?
Describe how competition can affect population size.
Describe what happens to a population when the death rate exceeds the birth rate.
Describe what is meant by the term 'carrying capacity'.
Explain the difference between density-dependent and density-independent limiting factors.
Explain what is meant by the term 'limiting factor' in population dynamics.
Explain why populations cannot grow indefinitely.
If a population is experiencing logistic growth, what happens as it approaches carrying capacity?
What is population density?
What is the difference between immigration and emigration?
