Term
|
Definition
| group of ecosystems with the same climax communities, biomes on land are called terrestrial biomes, those in water are called aquatic biomes. |
|
|
Term
|
Definition
| The climate of the region defines the biome. |
|
|
Term
| What are the aquatic biomes? |
|
Definition
| There are fresh water and marine water biomes. |
|
|
Term
|
Definition
Photic zone (shallow, sunlight penetrates) Along most coastlines.
Estuary (coastal where salt water and fresh water mix,partially surrounded by land. Intertidal zone (portion of the shoreline that lies between the high and low tide. Aphotic zone (is the deepest, least explored areas of the ocean with little or no light) |
|
|
Term
|
Definition
| Small organisms that drift and float in the water of the photic zone. MOST SEA CREATURES DEPEND ON PLANKTON FOR FOOD. |
|
|
Term
| What are the freshwater biomes? |
|
Definition
| Lakes, ponds, wetlands, swamps, and marshes. |
|
|
Term
| What abiotic factor limits life in deep lakes? |
|
Definition
|
|
Term
| Name the terrestrial biomes? |
|
Definition
| Tundra (treeless land) Taiga (coniferous trees) Desert (arid region with hardly any plant life) Grasslands (rich soil, grasses, and plants)Temperate forest (large diciduous trees) Tropical rain forest (warm temperatures, wet weather, lush plant growth) |
|
|
Term
| Name biomes of North America? |
|
Definition
| Desert, grasslands, tundra, deciduout forest, taiga, tropical rain forest |
|
|
Term
| Why do various combinations of abiotic and biotic interacting in different places in the world result in? |
|
Definition
| The result is that conditions in one part of the world are suitable for supporting certain forms of life, but NOT all life. |
|
|
Term
| What is a limiting factor? |
|
Definition
| It is a biotic or abiotic factor that limits or restricts the existence, numbers, reproduction, or distribution of an organism. |
|
|
Term
| What are some limiting factors? |
|
Definition
| High elevations, low temperatures, strong winds, soil to thin to support the growth of anything except small shallow-rooted plants, mosses, ferns, and lichens. SUNLIGHT, CLIMATE, TEMPERATURE, WATER, NUTRIENTS/FOOD, FIRE, SOIL CHEMISTRY, SPACE, OR OTHER ORGANISMS. |
|
|
Term
| What is tolerance factor? |
|
Definition
| It is the ability of an organism to withstand changes in biotic and abiotic environmental factors. |
|
|
Term
| When are the limits of an organisms tolerance reached? |
|
Definition
| When the organism receives too much or too little of some environmental factor. |
|
|
Term
| How does the organism respond when their limits of tolerance have been reached. |
|
Definition
| The organism responds by becoming smaller as conditons move toward either of the availability of resources. |
|
|
Term
|
Definition
| It is the orderly, natural changes and species replacement that takes place in the community of an ecosystem. |
|
|
Term
| What is primary succession? |
|
Definition
| It is the colonization of barren land by communities of organisms. Primary succession takes place where no other organisms live. |
|
|
Term
| What is a climax community? |
|
Definition
| A stable, mature community that undergoes little or no change over time. |
|
|
Term
| What is secondary succession? |
|
Definition
| It is the sequence of changes that takes place after an existing community is severely disrupted in some way. This can take place on land where life was previously contained and still contains soil. |
|
|
Term
| What is an example of secondary succession? |
|
Definition
| Yellowstone National Park fire of 1988. |
|
|
Term
| What are limiting factors of the intertidal zone? |
|
Definition
| Low tides isolate organisms, which also causes changes in nutrient and oxygen levels from one time of day to another. |
|
|
Term
| What causes the rise and fall of the ocean tides? |
|
Definition
| The gravitational pull of the sun and moon causes the rise and fall of the ocean tides. |
|
|
Term
| Why are plankton important? |
|
Definition
| They form the baseof all aquatic food chains. |
|
|
Term
| How does latitude effect climate as you move away from the equator? |
|
Definition
| At different latitudes the climate, wind, cloud cover, temperature, humidity and rain changes. As you move away from the equator the sun's rays strike less directly, because they are farther away. This effects the communities that will develop in these areas. |
|
|
Term
| What types of abiotic factors are working with latitude on climate? |
|
Definition
| Latitude and climate are abiotic factors that affect what plants and animals will survive in a given area. |
|
|
Term
| What are the two kinds of tundra? |
|
Definition
| Arctic and alpine tundra. |
|
|
Term
| Where would you find alpine tundra? |
|
Definition
| Alpine tundra can be found in high altitudes, 2 miles above sea level, in parts of Europe, Asia, and North America. |
|
|
Term
| Where will you find Arctic tundra? |
|
Definition
| As the name suggests in the Arctic. It has licen, mosses and permafrost. Taiga |
