Grade 6 Assignment

To study the biodiversity of insects in trees, scientists send clouds of insecticide up into the tree tops, then identify, count and study the dead insects that fall down. This is called:

• Mist netting

• Transect sampling

• Canopy fogging

• Quadrat sampling

Scientists use a method to count individuals and species in terrestrial and aquatic environments, where they stretch out a line with marked intervals. At each interval, they count the number of individuals and species. This is called:

• Mist netting

• Transect sampling

• Ariel photography

• Quadrat sampling

Scientists can study both birds and aquatic animals by safely catching them in fine mesh nets. When they are done, they often tag the animals then release them back into the ecosystem. This is called:

• Mist netting

• Surveying

• Ariel photography

• Quadrat sampling

Scientists often study bird populations by asking large groups of people to walk through, or check an area, counting what they see as they go. This is called:

• Canopy fogging

• Surveying

• Transect sampling

• Quadrat sampling

Scientists can study large herds of migrating land animals, or large aquatic animals like whales, by taking pictures from airplanes, helicopters or drones. This can also be used to measure biodiversity of trees in a forest, but is not useful for small animals or insects. This is called:

• Canopy fogging

• Surveying

• Ariel photography

• Quadrat sampling

Scientists sometimes mark out squares from 1m² to 20m², then count all the different individuals and species within these squares. They can do many squares, then take an average to estimate biodiversity. This is called:

• Canopy fogging

• Mist netting

• Transect sampling

• Quadrat sampling

In one quadrat, a scientists measured 100 individuals, coming from just 5 different species. What is the biodiversity index of this area?

• 0.05

• 0.02

• 0.2

• 0.5

Along a transect line, a scientists measured 10 individuals, coming from just 2 different species. What is the biodiversity index of this area?

• 0.05

• 0.02

• 0.2

• 0.5

A biodiversity index of 0.9 shows:

• very high biodiversity

• very low biodiversity

• False
