Biodiversity
What is biodiversity?
The variety of life; variability of all living organisms
Where is one of the most biodiverse places in the world?
What is the Amazon rainforest or great barrier reefs?
What is the main threat to biodiversity?
What are humans?
Species Diversity is....
The number and relative abundance of species in a biological community.
An example of a keystone species within the Kelp Forests
Otters
The type of biodiversity that shows the different genomes in one population
What is genetic diversity?
Ture or false: If an organism is removed from a food web then the ecosystem will fall apart. Explain.
False. The higher the biodiversity the more stable the ecosystem.
What is an example of a threat to biodiversity?
what is pollution, habitat loss, climate change, poor land management, overfishing, invasive species, etc
What is an endemic species?
Some species specific to a particular ecosystem
This species has narrow niches; more vulnerable (e.g. Panda Bear)
Specialist species
What are the three types of biodiversity?
What is species biodiversity, ecosystem biodiversity, and genetic biodiversity.
What does species biodiversity measure?
The total number of species in an area.
What makes an ecosystem stronger to threats?
What is increased biodiversity?
What is an invasive species?
Species which is a non-native plant/animal introduced accidentally or intentionally by humans
This species has broader niches; less vulnerable
Generalist species
The teosinte plant providing pest resistant genes to corn is a direct value of this type of biodiversity.
What is genetic diversity?
Increased CO2 levels, climate change, habitat loss, etc.
A species in danger of extinction...
An endangered species
This species has no natural predators
Invasive species
This occurs to biodiversity as we move closer to the tropics.
What is increase?
what is the functional role an organism plays in an ecosystem?
What is a niche?
Can a disrupted ecosystem be fixed? How?
what is reintroducing keystones species to the ecosystem
Bees are considered a keystone species because...
They pollinate flowers that produce fruit which supports the ecosystem.
What are the 3 types of biodiversity?
Genetic, Species, Ecosystem
