Biology- Biodiversity & Ecosystem Services

What would most likely result from the deforestation of large areas of tropical rain forests caused by slash-and-burn agriculture?

Cultural services.

What best explains how environmental stressors, such as wildfires, can affect biodiversity in an ecosystem?

Ecosystems with more species diversity are more likely to recover after a disturbance than ecosystems with low species diversity.

What are externalities, and give examples of them.

Externality is intangible, hides cost from the consumer, hinders the development of green goods, promotes pollution from smokestacks.

What is most likely to be the direct result of lack of genetic diversity in a food crop such as corn?

Increased susceptibility to plant disease.

What describes the disruption of an ecosystem service by an anthropogenic activity?

Land-use change, pollution, introduced species, resource exploitation

What would be categorized as a cultural ecosystem service of forests?

Recreation and tourism

What best describes a supporting ecological service provided by wetlands? Nutrient cycling.

Regulating services.

What can be estimated from the sample for the invertebrates in the pond?

Species diversity and species richness/ evenness.

What can be used to assess the biological diversity of an area?

Species richness and species evenness.

The consumption of mosquitoes by bats and the control of flooding provided by tropical forests in mountainous areas of Central America are examples of what?

Supporting services.

Why is genetic diversity important?

The more genetically diverse a population is, the better it can respond to environmental stressors.

What is a measure of the biodiversity of an ecosystem?

The true way to measure biodiversity in an ecosystem is to measure the genetic variation within each species and number of species present.

What best describes why most of these species went extinct?

There was a lack of resources.
