Which strategy below is specific to managing productive soils?

• Rotating monoculture crops to repair nutrients in the soil

• Using fertilisers to keep nutrients in soil

• Clearing land to increase sunlight

• Removing mulch from soil

Define 'old growth forest'

• Significant ecosystems with high biodiversity

• Significant ecosystems with low biodiversity

• Really old forests with ancient trees

• A forest that only contains old trees

Which strategy below is specific to managing old growth forests?

• Regularly allow backburning to manage waste products on forest floor

• Remove younger trees so they don't outcompete older trees

• Restricting logging activities

• Minimise introduction of protected regions in ecosystems

Biodiversity:

• Only refers to the ecosystems in which particular organisms are found

• Results from the loss of some genes and gain of other genes in a range of different organisms

• Refers to the types of organisms found on Earth

• Refers to the variety of organisms, their genetic makeup and the ecosystems in which they are found

A student performed a study of the local park and listed all of the plant species present. The student named 60 different species. Identify the measure of biodiversity that the student has calculated.

• Species diversity

• Species richness

• Species evenness

• Species abundance
