Habitat and Niche 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 Habitat and Niche.
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 12
A frog lives in a pond, eats insects, and is preyed upon by birds. Identify its habitat and one aspect of its niche.
A plant species can grow in both sunny and shady areas, but in a forest, it is found only in sunny spots due to competition. What is the term for the range of conditions where it is actually found?
A population of lizards is found only on a single island and feeds exclusively on a certain insect. What type of niche does this population have?
A species of bird feeds on insects found on tree bark, while another species feeds on insects in the soil of the same forest. What ecological concept does this illustrate?
