Ecosystem Services
Scientists discovered that the bark of the Pacific Yew tree contains a cancer-fighting drug. What type of ecosystem service is this?
Provisioning service
A measure of the total amount of different species in an area.
What is species richness?
If a forest ecosystem has a primary productivity of 55,000 kcal/m2/yr and the producers use 20,000 kcal/m2/yr for respiration, what is the NPP of the ecosystem?
35,000 kcal/m2/yr
The abiotic conditions under which a species can survive and reproduce is called this
What is a "fundamental niche?"
This biome type is found above the Arctic Circle and has a layer of permafrost.
What is a tundra?
Trees capture and store carbon as part of the carbon cycle. What type of ecosystem service is this?
Regulating service
A measure of the comparative number of different species in an ecosystem
Species evenness
In this food chain, which organism is the secondary consumer?
grass---> bunny---> fox----->hawk
What is the fox?
This occurs when a large number of species go extinct over a short period of time
What is a "mass extinction?"
This biome is dominated by plants (like cacti) who are specially adapted to conserve water as they have a very low annual precipitation.
What is a desert?
Freshwater biomes supply that majority of drinking water for people and livestock. What type of ecosystem service is this?
Provisioning service
These types of species can live in a wide range of habitats, eat a wide variety of food and have a high ecological tolerance.
What are generalist species?
In this food chain, which organism would be in the fourth trophic level?
grass---> bunny---> fox----->hawk
What is the hawk?
This type of succession begins from bare rock.
What is primary succession?
This biome is dominated by trees that lose their leaves every winter to conserve water, then grow back in the spring. There are four distinct seasons
What is temperate deciduous forest?
Bees aid in the pollination of wildflowers and food crops. What type of ecosystem service is this?
Supporting service
This is the biggest threat to biodiversity today
What is "Habitat destruction?"
The majority of nitrogen on the planet can be found here.
What is the atmosphere?
This type of succession would occur after a forest fire
What is secondary succession?
In this biome, animals (like elephants and wildebeests) are specially adapted to migrate in order to find sources pf water, as there are distinct wet and dry seasons.
What is the savanna?
Humans have traveled to the Mohave Desert for years to enjoy the majestic sunsets and paint the landscape. What type of ecosystem service is this?
Cultural service
This type of species has moved in to a non-native habitat and is outcompeting the native species.
What is an invasive species?
Which biogeochemical cycle does not have an atmospheric component?
What is the phosphorus cycle?
The range of abiotic conditions under which a species actually lives.
What is a realized niche?
This coastal off-shore biome has the highest NPP of all the marine biomes. It is also known for its high species biodiversity.
What is a coral reef?
