The overuse of animal and plant species by humans for food, medicine, or clothing is called this.
overexploitation
Cutting down forests or changing a habitat so much it is no longer usable is called this.
habitat destruction
This type of ecosystem service includes foods, fresh water, and timber — goods humans can take directly from ecosystems.
provisioning services
Scientists take pictures from above (from planes or satellites) to map and measure large areas — this method is called this.
aerial photos
Which of the following is NOT used to control invasive species:
Herbicides
Weeding
Reclamation
The use of other species
Reclamation
The variety of ecosystems in the biosphere is known as this.
ecosystem diversity
This service includes the filtering of water by wetlands or forests removing contaminants; it helps maintain clean water.; also includes climate control, erosion control
regulating services
Which type of biome has the most biodiversity?
Tropical rainforest
The number of different species and the quantity of each species in an ecological community is called this.
species diversity
What is the main source of greenhouse gases in the atmosphere?
humans burning fossil fuels
This method uses a straight line or belt where species presence and counts are recorded at intervals to sample biodiversity across an area.
transect sampling
This term describes the variety of genes or inherited traits present in a population.
genetic diversity
What is the relationship between biodiversity and ecosystem resilience?
The _____________ the biodiversity, the __________ resilient it is
The higher the biodiversity, the more resilient it is
The process of restoring land disturbed by mining is called this; it helps reduce habitat loss from extraction.
reclamation
Compare the health of 2 ecosystems, one with a biodiversity index of .65 and one with 0.23
answer will vary
This category of ecosystem services includes water cycling and nutrient cycling — processes that support life and other services.
supporting services
This process involves planting trees to replace trees that have been cut or burned down.
reforestation
This term names the geographic areas on Earth that contain ecosystems with similar biotic and abiotic features
biome
This type of ecosystem service involves benefits like hiking, swimming, and tourism from natural areas.
cultural services
Biodiversity is maintained or strengthened; overexploitation
A biodiversity index closer to 0 indicates this about an ecosystem's biodiversity and relative health.
lower biodiversity meaning less healthy or resilient
A group of organisms that have similar traits and can produce fertile offspring are called this.
species
An organism introduced (accidentally or on purpose) that spreads and outcompetes native species is this.
Invasive species
Scientists spray a low dose of insecticide into tree canopies to collect insects for counting and identification; this method is called this.
canopy fogging
