Question

9 What is the advantage of
using an outer and an inner
container instead of just one
container for the pitfall trap?​

Answer 1

Answer:

A pitfall trap is a trapping pit for small animals, such as insects, amphibians and reptiles. Pitfall traps are mainly used for ecology studies and ecologic pest control.[1] Animals that enter a pitfall trap are unable to escape. This is a form of passive collection, as opposed to active collection where the collector catches each animal (by hand or with a device such as a butterfly net). Active collection may be difficult or time-consuming, especially in habitats where it is hard to see the animals such as thick grass.
