What is the first step in investigating dispersal by dropping fruit seeds?
calculate the average dispersal distance
decide on a fixed height to drop all seeds from
measure how far along the ground the seeds travelled
obtain fruit containing seeds
|
How many times should you repeat the seed drop for each seed type?
twice
once
at least three times
|
What is the purpose of adding a fan to the seed dispersal experiment?
to make the seeds drop faster
to cool down the experiment area
to simulate natural conditions
to create wind and test its effect on seed dispersal
|
What should be measured after dropping the seeds?
the distance the seeds travelled along the ground
the height from which the seeds were dropped
the weight of the seeds
the time taken for the seeds to reach the ground
|
What is the last step in investigating dispersal by dropping fruit seeds?
measuring the distance the seeds travelled
repeating the experiment for each seed type
dropping one seed at a time from a fixed height
calculating the average dispersal distance
|
What should be compared when using a fan in the seed dispersal experiment?
travel distances with fan on versus off
travel distances from different drop heights
travel distances at different fan speeds
travel distances of different seed types
|
List three important factors to control when investigating seed dispersal as a fair test.
