General Patterns Found Across All Biomes Biomes are not completely distinct entities, but grade from one into another depending on the environmental conditions in an area. The area where one particular biome grades into another biome is called a/an... (Use the correct term found in section 52.2 of Campbell Biology.) O Climograph O Ecotone Ecozone O Edge

Wetlands remove nutrients like nitrogen and phosphorus from the water column, reducing the likelihood that the water discharged from the wetlands will stimulate excess primary production in downstream lakes or estuaries. In what class of ecosystem services is the removal of such pollutants? O cultural supporting O provisioning O regulating O safe operating zone

Some Aleutian Islands are surrounded by urchin barrens while others are surrounded by kelp forests. Which statement gives the primary explanation for these differences? O The kelp forest islands experience a substantially warmer climate than do the urchin barren islands. Grazing by urchins prevents the formation of kelp forests. Kelp forest islands and urchin barren islands differ with respect to oceanic currents. O Kelp eat urchins, thus preventing their establishment.

Which of the following descriptions about the organization of an ecosystem is correct? O Individuals of the same species are grouped in populations, which make up communities. O Individuals of the same species make up communities, which make up populations. Populations make up species, which make up communities. Communities make up species, which make up populations.
