Nutrients —————through an ecosystem

• Flow

• Cycle

• Decomposition

• Deposition

The cycling of water through the hydrologic cycle depends on

• Transpiration from plants

• Evaporation from the soil

• Pricipitation to the ocean

• All of the above

Hibernation happens during....and Estivation happens during...

• Summer, winter

• Summer,spring

• Winter,fall

• Winter,summer

Hypoosmosis is:

• High water concentration (inside) and low solute concentration

• High solute concentration (inside) and low fluids (outside)

• High water concentration (outside) and low solute concentrat

• Same water concentration inside and outside

Relative humidity is:

• The measure of Water vapor density only

• The measure of Saturation Water vapor density only

• Controlled by evaporation

• Both A and C

Vapor pressure deficit is:

• Difference between WVP and SWVP

• Division of SWVP and WVP

• Equal to WVP + SWVP

• Multiplication of SWVP and WVP

Organisms disperse due to many reasons including:

• Climatic change

• Prey availability

• Colonization cycle

• Only A and B

Water potential <0 means:

• Less free energy in water

• High free energy in water

• High dissolved solutes

• Only A and C

Regular distribution is characterized by:

• Unequal change of being anywhere

• Limited resources

• Uniform distribution of resources

• Patchy resource distribution
