This is the placement of biomes throughout the Earth as a result of climate, particularly tem perature
This display graphically shows the energy that is available at each trophic level in a food chain
This is the position that an organism occupies in a food chain-what it eats, and what eats it
This is an ecological pyramid that shows graphically the population of each trophic level in a food chain
This is a limiting factor of a population density. These factors are usually abiotic factors
ten percent rule
states only 10% of energy available at one trophic level is actually passed up to the next
linear pathway for the transfer of matter and energy through an ecosystem by eating and being eaten.
An aquatic food web consists of phytoplankton -> krill ->seals -> sharks. The removal of which component is MOST LIKELY to cause an immediate impact on the food web?
temperature, precipitation, and salinity will change
Global climate change may produce major shifts in biomes for any given location because mean__
describes, Cairo, Egypt, and northwest Mexico; characterized by sparse rainfall and much temperature variation
tropical dry forest
describes an equatorial zone with moderate precipitation that fluctuates seasonally; characterized by warm temperatures year round.is located at tropical and subtropical latitudes. Though these forests occur in climates that are warm year-round, and may receive several hundred centimeters of rain per year, they have long dry seasons which last several months and vary with geographic location. These seasonal droughts have great impact on all living things in the forest.
describes the region west of the Mississippi River; characterized by limited precipitation, thick organic soils and extreme temperature variation in winter and summer
describes the terrestrial biome bordering the Mediterrranean Sea, coastal California, and the southern coast of Austrialia; characterized by wet winters and warm dry summers.The annual rainfall may reach 20-30 inches (64-76 cm), but in contrast to the grasslands, almost all of this falls in winter. Summers are very dry and all the plants — trees, shrubs, and grasses — are more or less dormant then.
temperate deciduous forest
describes biome in the eastern United States, north central Europe, and eastern China; characterized by stable precipitation and seasonal temperature variation
describes the Pacific Northwest of the United States and Nagasaki, Japan; characterized by heavy rainfall and relatively stable temperatures
major regional complex of similar communities -large ecological unit recognized primarily by its dominant flora/ vegetation
diagrams to depict annual patterns and monthly averages of temperature and precipitation.
is the coldest and driest biome on the planet. the biome's name means barren or treeless plain. It is noted for its frost-molded landscapes, permafrost, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. Dead organic material functions as a nutrient pool.
