Practise MYP Biology questions on 6.1 Habitat and review the explanations to check your understanding.
Use these questions for topic practice and to find ideas you want to revisit in your notes or lessons.
Why is 'food availability' categorized as a biotic factor rather than an abiotic one?
Which adaptation is specifically required for organisms living under the crushing pressure of deep-sea hydrothermal vents?
Why does food availability act as a primary biotic factor limiting the distribution of animal populations?
Which abiotic drivers are most characteristic of high-altitude habitats, requiring organisms to evolve adaptations like compact body forms and UV-screening pigments?
In environments such as polar regions and high altitudes, which specific biochemical adaptation is essential for preventing the formation of lethal ice crystals within an organism's tissues?
It involves interactions with other living organisms or their products
It is a constant factor that does not change over time
It only affects the growth of plants and not animals
It is a non-living environmental condition like temperature
Barophile-tolerant membranes
Intracellular salt balance
Antifreeze proteins
UV-screening pigments
It prevents the denaturation of enzymes
It acts as a physical barrier to migration
It changes the pH of the surrounding water
It provides the energy and nutrients necessary for survival and reproduction
Antifreeze proteins
UV-screening pigments
Low salinity and high temperature
High pressure and toxic chemicals
Extreme cold and high UV radiation
High moisture and stable air pressure
Halophilic ion pumps
Heat-stable enzymes
