Practise MYP Biology questions on 7.1 Interdependency 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.
To protect a single endangered species effectively, conservation management must account for __________.
Why is it often more effective to prioritize the conservation of keystone species rather than focusing on a single endangered plant species alone?
How does natural selection facilitate the process of coevolution between two interacting species?
Why does high specialization in a symbiotic relationship increase a species' vulnerability to extinction?
Which specific type of interdependency is illustrated by desert rabbits dispersing cactus seeds through their waste?
only the target species' population size
just the abiotic factors of the environment
exclusively the removal of all natural competitors
the species' habitat, food sources, and mutualistic partners
Protecting a keystone species maintains the entire ecosystem structure that supports many other species.
Keystone species are always at the top of the food chain.
Keystone species do not require abiotic factors to survive.
Keystone species are easier to catch and monitor.
By selecting for generalist traits that reduce the need for interaction
By ensuring that one species always becomes dominant over the other
By favoring traits in each species that increase the benefits of their interaction
By preventing any genetic changes in the interacting populations
Specialized species have too many predators.
Specialization leads to a decrease in genetic mutations.
Specialized species cannot reproduce asexually.
The species relies heavily on a single partner that may decline due to environmental change.
Reproductive dependence
Decomposer dependence
Feeding dependence only
Habitat dependence
