Invasive Species starts at 7 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Invasive Species.
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 7
Describe how invasive species can impact agriculture.
Describe one method used to control invasive species.
Describe one reason why it is difficult to remove invasive species once they are established.
Describe one way invasive species can harm native animals.
Explain how invasive species can affect human health.
A gardener notices a new plant spreading rapidly and crowding out other plants in the garden. What should the gardener do? (1) Ignore it, (2) Try to remove it, (3) Water it more, (4) Plant more of it
A lake is experiencing a rapid decline in native fish populations after the introduction of a new fish species. What is a likely explanation? (1) The new fish is a predator, (2) The new fish is a decomposer, (3) The new fish is a pollinator, (4) The new fish is endangered
