Which of the following statements about levels of biodiversity is correct?
Genetic biodiversity is a measure of the total number of genes in a community.
A narrow distribution of habitats leads to an increase in species diversity.
Global hotspots are areas where species diversity is thriving due to habitat restoration.
A population with high genetic biodiversity is better able to respond to environmental stressors.
Which of the following best explains how environmental stressors, such as wildfires, can affect biodiversity in an ecosystem?
After an environmental stress, a genetic bottleneck may occur, which will increase genetic diversity.
Habitat diversity will increase the available niches if the landscape becomes more uniform after a disturbance.
Ecosystems with more species diversity are more likely to recover after a disturbance than ecosystems with low species diversity.
Smaller populations are less likely to go extinct than larger populations, so the species diversity will remain constant.
A 163 square-kilometer (km2) small island is found 2,000km from the mainland. A second, larger, 230,000km2 island is found 1,000km from the mainland.

The rate of immigration is lower for the small island than for the large island.
The small island has niches that are more like the mainland than the large island.
The small island has more available resources than the large island.
The rate of species extinction is lower on the small island than on the large island.
Ecological tolerance is refers to

Inhabit only niches that have recently become available after the local extinction of another species.
Can live in many niches, easily adapting to many variables and eating a wide variety of food.
Have a low genetic variability, enabling them to live in a wide variety of habitats.
Increase biodiversity because they attract more species to the areas in which they settle.
