move up the food web results in a loss of
energy of about 10%
C. The fact that biomass increases as you move up
the food web
D. The number of decomposers found in a system

The science of understanding biodiversity is
Conservation Biology
the science concerned with preserving biodiversity is known as
Conservation Biology
T/F-Conservation biologists focus on protecting individual species and
maintaining or restoring entire ecosystems.
True
T/F- Conservation biologists work to understand the threats facing species and ecosystems.
True
species that are at risk for extinction; various threat levels have been identified, ranging from least concern to extinct are known as
Threatened Species
The Red-Cockaded Woodpecker is on the US’s
Endangered Species List. It is illegal to destroy forests
that have individuals. Based on this information, what
type of species best fits the woodpecker?
A. Invasive Species
B. Endemic Species
C. Indicator Species
D. Umbrella Species
D. Umbrella Species
an international treaty that regulates the
global trade of selected species
* Banned the trade of African elephant ivory in 1990.
* Various governing bodies across Africa and Asia have been lobbying to
ease those restrictions.
is known as
Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES)
When was the endangered species act passed?
1973
What act protects endangered species from government and private citizens
it also forbids trade in products made from endangered animals

A management strategy that focuses on protecting one particular species is known as
Single-species conservation
The focuses of public awareness campaigns aimed at generating interest in conservation in general; usually an interesting or charismatic species, such as the giant panda or tiger. This species is known as
Flagship Species
A management strategy that focuses on protecting an ecosystem as a whole in an effort to protect the species that live there
Ecosystem Conservation
An ecosystem conservation strategy that specifically identifies a suite of species, chosen because they use all the vital areas within an ecosystem; meeting the needs of those species will keep the ecosystem fully functional, thus meeting the needs of all species that live there is known as
Landscape Conservation
The scientific field that relies on species’ genetics to inform conservation efforts this is known as
Conservation Genetics
Geographic spaces on land or at sea that are recognized, dedicated, and managed to achieve long-term conservation of nature is known as
Protected Areas
Low-impact travel to natural areas that contributes to the protection of the environment and respects the local people is known as
Ecotourism
Arrangements in which a wealthy nation forgives the debt of a developing nation in return for a pledge to protect natural areas in that developing nation is know as
Debt-for-nature swaps
Assessing the monetary value of an intact ecosystem to inform how best to use an area is known as
Valuing ecosystem services
Species that are restricted to a geographical area and do not occur naturally in any part of the world is known as an
Endemic Species
Species that don’t live in biodiversity hotpot’s are called
Gap Species
T/F- Ecotourism is a win-win; it protects not only the species in question but also the humans who share its habitat
True
