BIODIVERSITY

BIODIVERSITY

the enormous variety of life on Earth

Multiple Choice

Which of the following are arranged from least inclusive to most inclusive?

• population > ecosystem > community > biosphere

• ecosystem > population > biosphere > community

• biosphere > ecosystem > community > population

• population > community > ecosystem > biosphere

Multiple Choice

Which of the following is NOT part of overall biodiversity?

• species diversity

• genetic diversity

• individual diversity

• ecosystem diversity

Multiple Choice

Which of the following best describes what biodiversity measurements are used for?

• To monitor ecosystem change and help decide on which species need support

• To monitor habitat changes and help improve the habitat

• To monitor species and help the ecosystem in which they live

• To monitor genetic changes and help the environment adapt to it

Extinction

when a group of organisms fail to adapt to the environment and therefore cannot survive

Types of Biodiversity

• genetic diversity

• species diversity

• ecosystem diversity

Conservation

care and protection of resources so that they can persist for future generations

 includes maintaining the diversity of species, genes, and ecosystems, as well as functions of the environment, such as nutrient cycling

Multiple Choice

Which of the following is NOT a category of identifying the value of a species to humans?

• Direct Economic Value

• Indirect Economic Value

• Aesthetic Value

• Environmental Value

Species Value

• Direct Economic Value

• Indirect Economic Value

• Aesthetic Value

Multiple Choice

Which of the following is a direct economic value of trees?

• providing shade and oxygen

• providing lumber

• providing good landscape

• providing protection from floods and landslides

Stability

describes the resilience to withstand changes that might occur in the environment

Population

group of interbreeding individuals of the same species

Population Growth

population size

population density

Multiple Choice

what is the term for the largest number of individuals of a population that the environment can support?

• carrying capacity

• lag phase

• population crash

• limiting factor

Multiple Choice

When a population grows past the ecosystem's carrying capacity, what happens to the population?

• Continues to grow

• The population will go extinct due to lack of resources

• The population starts to die off to return to carrying capacity

• The population grows then finds a new carrying capacity

Limiting Factors

can limit or prevent the growth of a population

can be biotic (food, mates, and competition) or abiotic factor (space, temperature, altitude, and amount of sunlight available )

Multiple Choice

Which of the following an example of biotic factors?

• availability of water

• presence of predators

• occurrence of flood

• location of the environment

Multiple Choice

Which of the following limiting factors is independent of the population density?

• abundance of food

• availability of shelter

• presence of clean water

• human activities

Types of Limiting Factors

• Density-independent limiting factor

• Density-dependent limiting factor

Multiple Choice

What point on the graph represents the carrying capacity?

• a

• b

• c

• d

Multiple Choice

What growth pattern describes a population whose growth rate slows or stops following a period of exponential growth?

• J-shaped

• Predator-prey

• Logistic

• Exponential

Multiple Choice

What is the carrying capacity of this population?

• 100

• 200

• 300

• 400

Multiple Choice

What type of growth is shown in the diagram?

• exponential growth

• predator-prey cycle

• logistic growth

• boom-bust curve

Multiple Choice

What do you call a period of rapid population growth?

• exponential growth

• birth control

• logistic growth

• migration

Multiple Choice

What type of growth occurs when disease and parasites are present?

• exponential

• J-shaped

• predator-prey

• logistics

Multiple Choice

Which of the following is NOT a challenge to a growing population?

• Overcrowding

• Housing shortages

• Overuse of resources

• Increased food supplies

Multiple Choice

Reproductive strategy is one of the ways to conserve species. What type of reproductive strategy do humans use nowadays?

• K-strategy

• R-strategy

• B-strategy

• D-strategy
