Habitat and Niche

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 11
Describe how environmental changes can affect an organism’s niche.
Describe the difference between a fundamental niche and a realized niche.
Describe the niche of a decomposer in an ecosystem.
Describe the relationship between a keystone species and its niche.
Explain how niche overlap can lead to competition between species.
A forest contains many different species of birds. Some feed on insects in the canopy, while others feed on seeds on the forest floor. What does this scenario illustrate? (1) Habitat overlap (2) Niche differentiation (3) Competitive exclusion (4) Mutualism
A grassland supports both grazing animals and burrowing rodents. What does this suggest about the grassland’s ecological structure? (1) It has only one niche (2) It supports multiple niches (3) It is a poor habitat (4) It has no competition
A lake contains both trout and bass, which feed on different prey and occupy different depths. What does this indicate about their niches? (1) They have identical niches (2) They have overlapping habitats but different niches (3) They are in direct competition (4) They are mutualists

True or False: A generalist species has a narrow niche.
True or False: A habitat can contain many different niches.
True or False: A specialist species is more vulnerable to habitat loss than a generalist species.
True or False: Abiotic factors are not part of an organism’s niche.
