• Air Purification
• Pollination
• Water Purification

Question 4

Term that describes local extinction

Answer 4

Extirpation

Question 5

Term that describes the species that maintains biodiversity in a population

Answer 5

Keystone Species

Question 6

Define Extinction Vortex

Answer 6

Way that extinctions happen in small populations. Populations lose alleles.

Question 7

What 2 things lead to an extinction vortex in small populations?

Answer 7

• Genetic Drift
• Inbreeding

Question 8

What do populations have to stay above to avoid extinction vortex?

Answer 8

Minimum Viable Population (MVP) - Shai

Question 9

Describe Small Population Approach (SPA). Is it a new or old approach?

Answer 9

Humans attempt at stopping an extinction from occurring. Older approach.

Question 10

Describe Declining Approach. Is it a new or old approach.

Answer 10

Humans look systemically at what is declining in an ecosystem. New approach.

Question 11

What is Fragmentation?

Answer 11

Process by which a habitat is divided into smaller, isolated parts.

Question 12

An area that is set aside and will not be developed is known as a:

Answer 12

Nature Preserve

Question 13

Define Overharvesting

Answer 13

Rate of hunting is greater than the rate of production. Leads to decline in population

Question 14

List some conservation stat

Answer 14

• Small Population Approach
  _Movement Corridors
• Nature Preserves
• Declining Approach
