If all members of a species disappear from Earth, the species is said to be
extinct
keystone
threatened
endangered
The mating of condors in zoos is an example of
biodiversity
captive breeding
habitat destruction
habitat preservation
The loss of a natural habitat is called
habitat destruction.
habitat fragmentation.
pollution.
poaching.
National Natural Park like Tayrona, is an example of:
captive breeding
habitat preservation
poaching
habitat destruction
Laws can help protect endangered species by prohibiting:
products made from the species
habitat preservation.
diversity of genes.
captive breeding
The most diverse ecosystems on Earth are
tropical rain forests
deserts
coral reefs
deep-sea areas
The exhaust fumes (gases coming from the car) from automobiles are an example of:
habitat destruction.
pollution
poaching
exotic species
A species that influences the survival of many other species in an ecosystem is called a(n):
extinct species
exotic species
endangered species.
keystone species
Wildlife tourism, or “ecotourism”, is an example of the ecologic value of biodiversity.
TRUE
FALSE
A diverse pool of (a) helps ensure that individuals in a species will pass a variety of traits to their offspring.
The illegal killing or removal of wildlife species from their habitats is called (a) .
Some relationships among some marine organisms:
Otter eats Sea Urchins. The Sea Urchins eats Kelp. Other species like the fishes depend on Kelp to find shelter.
According with this information, if the number of Otters decrease due to poaching, what will happen to the Kelp forest?
Increase
Decrease
Stays the same
The major cause of extinction is habitat fragmentation.
TRUE
FALSE
Protecting whole ecosystems is the most effective way to preserve biodiversity.
Whole definition: 1. all of; entire.
TRUE
FALSE
Biodiversity has both (a) and ecological value within an ecosystem.
Soccer fields are most often made of one single type of grass. What type of biodiversity do sports fields show?
High "Rich" biodiversity because there is only one type of producer.
Low "Poor" biodiversity because there is only one type of producer.
High biodiversity ensures that many different ecological niches (jobs, roles) are filled, which helps the ecosystem function well.
True
False
High biodiversity makes it more likely that the ecosystem will be able to keep functioning after a disturbance, such as disease or natural disaster.
True
False
What are some ways we can help in maintaining biodiversity?
Get involved with ecological restoration in your area.
Prevent invasive species from overpopulating.
Don't use chemical pesticides on crops.
All of the above
Biodiversity is....
The biological variety and variability of life on Earth. The measure of variation at the genetic, species, and ecosystem level.
Number of species in an environment
Diversity of plants
Diversity of animals
Food Web B is an example of...
Low biodiversity and low sustainability. If the producer dies then all the food web will suffer.
High biodiversity and high sustainability. If an organism is removed the food web will continue with no effect.
