Osmosis

Migratory
wandering, migrating; to move from one region and settle in another; move periodically from one region to another

Abiotic
nonliving, physical features of the environment, including air, water, sunlight, soil, temperature, and climate
tolerance range
the range of conditions that an organism can survive in
leaching

Transpiration
the process by which water is lost through a plant's leaves
Closed forests
area in which tree crowns cover most of the ground
stomata

dormancy
A condition typified by extremely low metabolic rate and a suspension of growth and development.
