| Question | Answer |
|---|---|
| Fields that contribute to environmental science | biology, earth, chemistry, physics and social sciences |
| the law of supply and demand describes | the relationship between the availability and the worth of resources. |
| Type geological activity that formed the Himalaya Mountains | colliding tectonic plates |
| In nature what do wind and water erosion affect the most? | mountains, rocks and soil |
| Examples of an ecosystem | vacant lot, oak forest, coral reef |
| WheretThe energy in most ecosystems comes from | the sun |
| Plants and other producers get their energy directly from | the sun |
| Animals get their energy from the sun | indirectly |
| Rare bacteria that live deep in the ocean get their energy from | hydrogen sulfide in hot water |
| Consumers get their energy | indirectly from the sun |
| organism obtains energy only from producers | herbivores |
| Examples of savanna animals | rhinos, gazelles, and giraffes |
| These are threatened by soil erosion because native grasses have been damaged or destroyed by plowing and overgrazing. | Grasslands, such as the prairies of North America |
| An environmental function of wetlands | absorbing and removing pollutants from water |
| An environmental function of wetlands | trapping carbon that would otherwise be released into the air |
| An environmental function of wetlands | controlling floods |
| These are very productive ecosystems because they receive fresh nutrients from rivers and oceans | Estuaries |
| An adaptation that evolves in response to other organisms is known as | coevolution |
| All of the organisms of the same species (such as a forest of maple trees) is an example of a | population |
| Professionals who study and make predictions about human populations are called | demographers |
| A population pyramid is created by graphing the distribution of this | ages in a population at a specific time. |
| An endangered species is... | a species in danger of extinction. |
| Number of species estimated to be living on Earth | 10 to 50 million |
| effective strategy in slowing the loss of biodiversity | creating large parks/preserves in biodiversity hotspots |
| factor contributing highly to the exponential growth of the human population | more food, better hygiene |
| The density of a population is | the number of individuals per unit area. |
| What causes most coastal pollution in the United States | industrial waste and sewage |
| The adaptation of phytoplankton which prevents them from sinking into deep waters | flagella |
| a tropical rain forest has species of animals with specialized ways of surviving in order to avoid this? | competition |
| amount of energy carried through from organism to organism in the food chain | 10 percent |
| Humans are an example of organisms most likely to belong to the same… | species |
| most geologically active region on the surface of Earth | boundaries between tectonic plates |
| an example of a renewable resource | wood, water, sun, wind |
| an example of a non-renewable resource | gasoline, metal, coal, oil |
| Most of today’s environmental problems began during which period(s) in human history? | Industrial |
| Refers to the number and variety of species that live in an area | biodiversity |
