QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Community Interactions.
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 8
Describe how predation can affect the population size of prey species.
Describe one example of parasitism found in nature.
Describe the role of competition in shaping community structure.
Describe what happens in a predator-prey cycle.
A bird eats insects off the back of a buffalo. The bird gets food, and the buffalo gets rid of pests. What type of interaction is this? (1) Parasitism (2) Mutualism (3) Competition (4) Commensalism
A case study: In a forest, woodpeckers and squirrels both use tree holes for nesting. Over time, woodpeckers start using higher tree holes, while squirrels use lower ones. What is this an example of? (1) Resource partitioning (2) Parasitism (3) Mutualism (4) Amensalism
A fungus grows on a tree, causing disease and harming the tree. What type of interaction is this? (1) Mutualism (2) Parasitism (3) Commensalism (4) Competition
A small bird builds its nest in the branches of a tree. The tree is not affected. What type of interaction is this? (1) Mutualism (2) Parasitism (3) Commensalism (4) Competition
