Vocabulary Terminology for Chapter 28 in Friendly Biology
Question or Term | Answer or Definition |
---|---|
Ecology is | the study of the relationships between living things and their environments. |
Environment is | defined as being everything, both living & nonliving, which are found in the location where a living organism lives. |
Biosphere is | the segment of t he earth where life exists. |
Biome is | defined as an area of the earth where similar organisms thrive and others do not. |
Polar Biome is | found at the North & South Poles of the earth and average temperatures -40 F to 25 F & < 5" of precipitation in a year. |
Tundra Biome is | areas with short plants & few mammals due to temperatures of -28 F to 39F and < 10" of precipitation in a year. |
Coniferous Forest Biome is | characterized by evergreen, cone bearing trees & temperatures of 14F to 57F with precipitation being between 12-30" in a year. |
Deciduous Forest Biome is | characterized by predominance of trees which lose their leaves during cooler seasons & temperatures from 42F-82F with annual precipitation from 30-50". |
Grasslands Biome is | characterized by abundant grasses and few trees, but same latitude of Deciduous biome and temperatures slightly cooler and only 10-30" of precipitation annually. |
Desert Biome is | found in regions which are warmer on average than grasslands yet receive less precipitation. Temperatures range from 75F-94F with < 10" of precipitation annually. |
Rain Forest Biome | can be divided into categories, 1. tropical rain forest 2. Temperate rain forest . |
Tropical Rain Forest Biome is | along the equator & temps 77F-81F |
Temperate Rain Forest Biome is | along the western coast of North America with temps between 50F-60F |
The Marine Biome | consists of the earth's oceans and seas. |
The Freshwater Biome | consists of lakes, rivers, streams. |
Estuaries are | where river of freshwater mix with the salt water of a sea or ocean. |
Autotrophs are | organisms capable of capturing the energy of the sun and converting it to useable food for itself. |
Producers are | autotrophs or plants. |
Heterotrophs are | organisms that harvest energy captured from autotrophs. |
Consumers are | Heterotrophs, meaning we get our energy from plants or other animals that eat plants. |
Primary consumer | is a consumer or heterotroph that eats a producer or plant. |
Secondary consumer | is a consumer of primary consumers. |
Herbivores are | consumers whose sole food source are producers or plants |
Omnivores are | consumers whose food source are producers and consumers or plants and animals. |
Scavengers are | organisms that consume dead organisms. |
Amount of Available Energy is reduced with | with each step through an ecosystem away from the producer level. |
Biogeochemical cycles | demonstrate how chemical elements move round and round through living (bio-) and then nonliving portions (geo-) of the environment. |
