This aquatic ecosystem has a thin layer of water covering soil that is wet most of the time
wetlands
What term describes an ecosystem's ability to maintain dynamic equilibrium despite significant outside disturbances?
resilience
Soil formation, nutrient cycling, and primary production are examples of this broad service that supports other services.
supporting services
The region between the lowest low tide and the highest high tide is called this; it's home to organisms adapted to changing water levels.
intertidal zone
Benefits like recreation, spiritual value, and aesthetic enjoyment are part of this service type.
cultural services
A geographic area on Earth with ecosystems that have similar biotic and abiotic features
biome
The biodiversity index is calculated by
dividing the number of species by the total number of individuals
the number and variety of living things found in a specific region.
biodiversity
How many species have scientists identified so far?
2 million
This method captures birds by using fine nets suspended in trees or along flyways.
mist netting
This category of ecosystem services includes pollination, water purification, erosion control, and climate regulation.
regulating services
What does a biodiversity index closer to 1 indicate?
greater biodiversity
This method of sampling involves spraying insecticide into tree canopies to collect falling arthropods; it's used to study canopy species.
canopy fogging
This ecosystem is described as "among Earth's most fertile ecosystems" and frequently filters water and supports many plants and animals.
wetland
This biome is characterized by very little rainfall and covers about one-third of Earth's land mass
desert
which forest biome has the highest level of biodiversity
tropical rain forest
What taxonomic group has the highest number of known species according to the graph in the text?
insects and arthropods
This underwater structure is built from the skeletons of tiny coral animals and supports many marine species.
coral reef
These ecosystem services provide goods such as food, water, and medicine.
provisioning services
This method of measuring biodiversity involves placing a square frame on the ground and counting organisms inside it.
quadrat sampling
A region where freshwater meets saltwater
estuary
This biome is also called a boreal forest and is dominated by cone-bearing trees adapted to cold climates.
taiga
This biome has cold, treeless plains and often has permafrost (frozen ground).
tundra
Which of these is NOT a type of biodiversity: Genetic diversity, Species diversity, Ecosystem diversity, or Geographic diversity
Geographic diversity
his sampling technique involves laying out a line across a habitat and recording organisms encountered along it.
transect sampling
