Importance and Risks



What is Biodiversity?

• BIO means - "Life"

• Diversity means - "Variety"

Biodiversity

The variety of organisms in an area, by species, genes, populations, and communities, also called biological diversity.

Multiple Select

The variety of organisms in an area, is also called biological diversity.

It is identified by which of the following? (Check all that apply)

• species

• genes

• populations

• communities

• type of cell phone

The three main parts of Biodiversity

• Species Diversity

• Genetic Diversity

• Ecosystem Diversity

Species Diversity

Is the number or variety of a species in a particular region

Genetic Diversity

Describes the differences in DNA among individuals within species and poluations.

Ecosystem Diversity

The number and variety of ecosystems within a given area.

Multiple Select

What are the three main parts of Biodiversity? (Check all that apply)

• Endangered

• Species

• Genetic

• High Risk

• Ecosystem

Multiple Choice

What does genetic diversity provide?

• generates new species, adding to species diversity, whereas extinction decreases species diversity.
• the raw material necessary for adaptation to local conditions
• taxonomic groups and geographic regions
• Summarizes population trends for a set number of terrestrial, freshwater, and marine species that are closely monitored and provide reliable data.

Multiple Choice

What is ecosystem diversity...??..

• Number of different species in the biosphere.
• Regional extinction.
  
• A species whose numbers are so small that the species is at risk of extinction.
• The variety of ecosystems that are present in the biosphere.

Multiple Choice

What is Species diversity?..?...

• the number or variety of species in the word or in a particular region 
• The range of genetic material present in a gene pool or population of a species.
• The variety of ecosystems that are present in the biosphere.
• A species whose numbers are so small that the species is at risk of extinction.

Multiple Choice

What are the 3 types of Biodiversity 

• sedimentary, metamorphic, and igneous
• genetic diversity, Ecosystem diversity, species diversity
•  ionic, covalent and metallic
• mRNA, tRNA, rRNA

Multiple Choice

What is the most important biotic factor in supporting an ecosystem?

• water

• sunlight

• herbivores

• producers

Multiple Choice

Which of the following would cause biodiversity to DECREASE?

• Water

• Forest Fires

• Sunlight

• Producers

Multiple Choice

A certain area of the Indian ocean is expected to dry up and become a desert over thousands of years. What will happen to the sustainability of this ocean?

• Sustainability would increase because the number of species would increase

• Sustainability would remain the same

• Sustainability would decrease because the number of species would decrease

• Not enough information is given

Multiple Choice

What is true about sustainability?

• Having a small number of species increases biodiversity

• Sustainability is how organisms change over time

• Sustainability is how much rainfall and sunlight an ecosystem receives

• The more different types of species you have (biodiversity) the better an ecosystem can sustain itself

Multiple Choice

What two factors would make biodiversity increase?

• Tornadoes and hurricanes

• Large amount of producers and water

• More predators and competition

• The water cycle and ocean warming

Multiple Choice

Anastayjia visited 3 different ecosystems to collect specimens. She visited a grassy area in a tundra and woody area in a Temperate deciduous forest. She collected 20 different types of species from the tundra and 98 different types of species from the forest. Which ecosystem is the MOST sustainable?

• Tundra

• Desert

• Temperate deciduous forest

• Rainforest

Importance of Biodiversity

• Ecosystem Function

• Agriculture

• Medicine

• Tourism and Recreation

Multiple Choice

The ecosystem approach to conservation is partly based on the idea that:

• a healthy biosphere requires intact ecosystems.

• human needs are of secondary importance.

Multiple Choice

The level of biodiversity that involves a variety of habits and communities is _____ diversity.

• ecosystem
