This activity contains 20 questions.

	An ecosystem is comprised of   solely living components. solely nonliving components. living and nonliving components that do not interact. living and nonliving components that continually interact. living and nonliving components that sometimes interact.

	The largest reservoir of carbon is the   soil. atmosphere. ocean. vegetation. sedimentary rocks.

	In terms of a food chain or food pyramid, organisms that trap energy, such as plants, are known as   carnivores. tertiary consumers. primary consumers. herbivores. primary producers.

	The boundaries between biomes (ecotones) are usually seen as   gradual transition zones. abrupt changes in vegetation, but not of animals. abrupt changes in both vegetation and animals. distinct topographic barriers such as mountains and rivers. abrupt changes in animals, but not of vegetation.

	Which of the following lists contains all the ingredients and products of photosynthesis?   carbon dioxide, water, oxygen, and carbohydrates oxygen, nitrogen, water, and carbohydrates phosphorus, water, carbon dioxide, and oxygen carbohydrates, water, nitrogen, and carbon dioxide carbon dioxide, water, ozone, and carbohydrates

	Why is it difficult to integrate nitrogen gas from the atmosphere into the nitrogen cycle of the biosphere?   Nitrogen is not very abundent in the atmosphere. Few organisms can directly utilize atmospheric nitrogen gas. Most plants do not require organic nitrogen compounds for survival. Oceans quickly absorb nitrogen gas. Living organisms quickly absorb nitrogen gas.

	Which of the following is not one of the five kingdoms of the Linnaean classification system?   animalia monera protista fungi chordata

	Why do trees need more moisture than grasses to survive?   Grasses do not use water in photosynthesis. Grasses do not lose water to the atmosphere through transpiration. More moisture is required to move the greater distance between the roots and leaves in trees than grasses. Grasses do not have roots. Trees do not lose moisture through transpiration.

	What human activity has added the most carbon to the atmosphere?   burning fossil fuels mining fossil fuels cutting down the rain forests increasing soil erosion none of the above

	Which of the following factors influences biotic distributions?   moisture wind temperature light all of the above

	The biosphere encompasses the total _____ of living material in a region or the globe.   diversity of species phyla animal population photosynthesis weight

	In nutrient cycles in general, minerals tend to be dispersed through _____.   plant action surface and subsurface runoff evaporation assimilation conduction

	Organismic response to the length of exposure to light in a 24-hour period is called _____.   photoperiodism photosynthesis diurnalism dentrification nitrification

	Soil chemistry is considered a(n) ____factor.   topographic econtonal biologic edaphic none of the above

	____ fixes carbon in green plants as simple sugars.   Denitrification Photosynthesis Carbonation Hydrolysis Bacteria

	Oxygen is contributed to the atmosphere by   green plants. the weathering of rocks. water from plant transpiration. fossil-fuel combustion. all the above.

	Bacteria drives the ___ cycle.   carbon oxygen energy hydrologic nitrogen

	In global biome patterns, ____ characteristics are the most important factor affecting distribution.   general geologic general topographic general climatic general soil general moisture patterns

	____ are floating ocean plants and animals.   Nekton Benthos Plankton Terrenus None of the above

	The broadest category of organism in biological taxonomy is _____.   the phylum (division) the class the family the species the kingdom
