Ess Topic 8

The units of measurement for the Simpson's diversity index is ...?

Determining the number of species in an area is known as

• Species richness

• Biodiversity

• Biomass

• Total population

• What the organisms eats

• Response to climatic factors

• The organisms physical features

Which of the following characteristics below would be most helpful in distinguishing leaves in a dichotomous species identification key?

• The leaf turns red in autumn

• The leaf has a serrated (rough) edge

• The leaf is eaten by ants

• The leaf is 10 cm long

A student wishes to determine how the decrease in pollution levels affect plant diversity with distance from a highway into a forest. Which sampling technique would the student need to use?

• Random sampling

• Stratified sampling

• Transect sampling

What is this a diagram of?

When would a groundwater aquifer become unsustainable?

• When more water is extracted than is replenished

• When the zone of replenishment is higher than the extraction point

• When more water is replenished than is extracted

• When the groundwater becomes lower than the well head

Two ways which sustainable water use in cities could be achieved would be:

• Use of low water demand crops so less water is used

• Expand metering - charge only for the water used

• Increase the use of drip irrigation methods to reduce water wasted as evaporation

• Make new buildings more water efficient by recycling more water in their devices and appliances

• Store more water underground in gravel-filled reservoirs to reduce evaporation
