A consumer that feeds on plants herbivore
A consumer that feeds on animals carnivore
A consumer that feeds on both plants and animals omnivore
A consumer that feeds on dead animals scavenger

An area of the Northwestern coast of the U.S. that has moderate temperatures and receives more that 300 cm of rain a year temperate rain forest
An area found near the equator that is warm and humid all year long, receives a lot of rainfall, and is home to an astounding variety of plants and animals tropical rain forest
A biome that has more evaporation than precipitation and receives less than 25 cm of rain per year. Organisms in these areas must be adapted to the lack of rain and extreme shifting temperatures. desert
A biome that is populated mostly by grasses and other nonwoody plants, has rich soil, receives anywhere between 50-120 cm of rain yearly, and is home to many of the largest animals on Earth grasslands
A biome that receives at least 50 cm of rain per year with temperatures that vary greatly during the year. This is the type of biome in which we live. deciduous forest
A biome found in areas of the northern hemisphere that has very cold winters and receives a lot of snow. Also known as the taiga, this area is home to mostly coniferous trees and a variety of animals. boreal forest
An extremely cold and dry biome that receives very little precipitation. Most of its soil is frozen all year and its plants and animals must be adapted to the cold climate. tundra
the process of changing free nitrogen gas into a usable form nitrogen fixation
the study of where organisms live biogeography
the very slow motion of the continents continental drift
the movement of organisms from one place to another dispersal
species that are carried to a new location by people exotic species
the typcial weather pattern in an area over a long period of time climate
a group of land ecosystems with similar climates and organisms biome
the process by which a gas changes to a liquid. During the water cycle, this is how clouds are formed condensation
the process by which molecules of a liquid absorb energy and change to a gas. In the water cycle, this is driven by the energy in the sun. evaporation
rain, snow, sleet, or hail precipitation
consumers breathe in _____________ oxygen
consumers release ________________ carbon dioxide
producers "breathe" in ___________ carbon dioxide
producers release _____________ oxygen
a human activity that raises the level of carbon in the atmosphere burning fuel
What energy role occupies the bottom of an energy pyramid? producers
At what level of an energy pyramid is there the least amount of energy? the top
You and your classmates have just set up a terrarium in a jar using gravel, moist soil, leafy plants, and mosses. The day after the jar was sealed, you noticed water droplets on the inside of the jar. What process caused the water droplets to form? condensation
What energy role could apply to a carnivore? consumer
