What is population dynamics?
The study of biodiversity
The study of extinction
The study of genetics
The study of populations and how they change
What are the two types of limiting factors?
Natural and human
Density-dependent and density-independent
Controlled and uncontrolled
Abiotic and biotic
What does growth rate measure?
The biodiversity of a region
The size of an individual
The number of ecosystems in an area
How fast a population changes in size
What is exponential growth?
Population growth that increases faster as size increases
Population that remains at zero
Population that decreases steadily
Population that stays constant
What is logistic growth?
Population growth that never slows down
Population growth without limits
Population growth that always decreases
Population growth that levels off near carrying capacity
What is carrying capacity (K)?
The smallest possible population size
The average number of organisms in an area
The total biodiversity of an area
The maximum population size an ecosystem can support
What are r-strategists?
Species with zero growth
Species with rapid growth and high death rates
Species with slow growth and low death rates
Species at carrying capacity
What are K-strategists?
Species with short lifespans and no care
Species with few offspring and logistic growth
Species with rapid reproduction
Species with random distribution
What is biodiversity?
Only the number of animals
Similarity among organisms
Variation in living things
Only plant species
What does high biodiversity provide?
A decline in population size
A more balanced and resilient ecosystem
Only more plants
A smaller chance of survival
What is conservation biology?
Study of human demographics
Study and practice of protecting biodiversity
Study of extinct species
Study of climate change
What is a biodiversity hotspot?
A zoo with many species
Area with no living things
Location with many endemic species
A region with only plants
What is demographic transition?
When developed countries have fewer children
When populations reach zero growth
When birth and death rates are equal
When populations double in size
What are demographics?
Data on plants only
Information about human populations
Data on biodiversity
Information about extinct species
What is biomass?
The number of animals only
The food chain energy
The average plant size
All the matter in a biological population
What is habitat fragmentation?
Adding more water to an ecosystem
Destroying all plants in an area
Creating one large habitat
Breaking an ecosystem into small pieces
