Ecology - Ecosystems and Communities

The Earth’s climate is, in part, created by the interplay of

• temperatures, ecosystems, and wind

• landmasses, the atmosphere, and the ocean

• weather, heat transport, and the environment

• solar radiation, surface temperatures, and biomes

Climate is a global factor that produces

• Earth’s unique ocean and atmosphere

• the shape and elevation of landmasses

• a wide range of environmental conditions that shapes communities

• solar energy within the atmosphere

Earth has three main climate zones because of the differences in latitude and

• amount of solar energy received

• angle of heating

• ocean currents

• prevailing winds

The loss of heat to space is slowed by

• radiation entering the atmosphere.

• atmospheric gases.

• solar energy.

• the biosphere.

Which is NOT an adaptation that organisms have for living in flowing water?

• hooks

• plankton

• streamlined bodies

• suckers

Ponds and lakes are

• flowing-water ecosystems.

• wetlands.

• standing-water ecosystems.

• estuaries.

The chemistry of aquatic ecosystems is determined by the

• amount of salts, nutrients, and oxygen dissolved in the water.

• the number of other organisms present in the water.

• amount of rainfall the water receives.

• biotic and abiotic factors in the water.

Which animal would be found in the biome that has cold to moderate winters, warm summers, fertile

soils, and is home to a variety of vegetation, such as coniferous trees, broadleaf deciduous trees,

flowering shrubs, and ferns?

• white-tailed deer

• polar bear

• iguana

• moose

Which two biomes have the least amount of precipitation?

• tropical rain forest and temperate forest

• tropical savanna and tropical dry forest

• tundra and desert

• boreal forest and temperate woodland and shrubland

Which of the following can influence the climate in a small area within a biome?

• the average temperature and precipitation

• the latitude of the biome

• natural features such as a lake

• the greenhouse effect
