| Tropical rainforests have more different species and varieties of species of plants and animals than any other type of biome, therefore, they have the greatest ______ of any type of biome. | biodiversity |
| Species of organisms that were brought to a certain area by humans and then outcompete the species that have always been there and kind of take-over because they might not have any natural predators are called _____ . | invasive species |
| Even if the total amount of land is the same, if that land has undergone _____ by being broken up into patches by things like roads and housing developments going in, that land will not be able to support as much biodiversity as the same amount of land if that land is all grouped together. | habitat fragmentation (For example, a 1000 acre forest will support more biodiversity than ten fragments of forest that are 100 acres each. Even though it's the same amount of overall land, animals need have access to bigger populations of their own species, and bigger populations of diverse plants and prey species in order to survive well.) |
| Which type of terrestrial biome has the greatest biodiversity? | Tropical rainforest |
| The northern spotted owl is a(n) ____ because it can only live in very healthy biodiverse forests. | indicator species (their presence indicates the forest is healthy) |
| Organisms that are only found in one small area in the world are called ______. | endemic species |
| TRUE or FALSE: Many medicines were originally discovered in rainforest plants and animals. | TRUE |
| Two methods that are used to keep a species that is almost extinct from going extinct are _____ and _____. | captive breeding, cloning |
| Some species are so close to extinction that wildlife biologists try to raise them in zoos with the idea that they will eventually be trained to survive in the wild and released. The method of trying to save single species is called ________. | captive breeding |
| A method for making genetically identical organisms by taking the DNA out of an adult animal and putting it into a hollowed out egg cell, then implanting that cell into a surrogate mother who will give birth to a baby that is genetically identical to the adult animal whose DNA was used. This process is called _________ and the genetically identical offspring is called a(n) ______. | cloning, clone |
| One method for preserving biodiversity in the world is to focus conservation efforts on areas that currently have a lot important biodiversity but are losing the biodiversity rapidly, including endemic species found nowhere else in the world. These areas are called ____. | biodiversity hotspots |
| Healthy ecosystems provide many benefits to humans including the providing of clean water, air, food, fuel, and the prevention of droughts and floods plus they help prevent disease outbreaks. All these beneficial jobs that healthy ecosystems provide for us are referred to as "Ecosystem ______." | Services |
| Removal of a(n) _____ species from an ecosystem is likely to have negative effects on many other species and the health of the ecosystem as a whole. | keystone (Keystone species are species that are not great in number, but have a great effect on the ecosystem. We learned about them in the second marking period. Examples include wolves, prairie dogs, sea otters, bees, and coral) |
| Biodiverse ecosystems tend to be the most fragile types of ecosystems and are the most prone to be hurt by environmental change or pollution. | FALSE: Biodiverse ecosystems tend to be more resilient and stable than ecosystems that have started to lose biodiversity or were not diverse to start with) |
| A species that no longer has any living members on planet Earth is said to have undergone _____. | extinction |
| A species that no longer has any living members in a given area, but can be found elsewhere is said to have undergone ______. | extirpation |
| There have been ___ mass extinctions during the history of this planet, not including the mass extinction that seems to be underway today. | 5 (Most of them have been due to fairly sudden climate change, including the last one 65 million years ago where a giant meteorite struck earth and kicked up enough dust an debris into the atmosphere to block out the sun for awhile. Other mass extinctions have been caused by carbon dioxide levels spiking due to an unusually high amount of volcanic eruptions close together which led to a quick increase in global temperatures)) |
| Species that are introduced into a new part of the world by humans and manage to outcompete native species are called ______ species (the answer that I'm looking for is NOT "non-native") | invasive |
| Illegal hunting is called _____. | poaching |
| What is the greatest cause of biodiversity loss in the world? | Habitat loss and change |
| A population of organisms which are at risk of becoming extinct would be classified as ______ species. | endangered |
| A population of organisms which are at risk of becoming endangered would be classified as ______ species. | threatened |
| Which Law passed in 1973 requires the government to stop commercial activities that could lead to the extinction of a certain species? | The Endangered Species Act |
