B. areas with distinct plant communities and associated with particular climates
Biome refers to a large, relatively distinct terrestrial region that is characterized by similar climate, soil, plant communities irrespective of its location on the Earth. The large geographic area of a biome includes many interacting landscapes. Biomes mostly represent the major climate zones of the earth, with temperature and precipitation being most important.
For example, desert biomes are characterized by low precipitation, seasonal and daily variations in temperature and are homes to the perennials and annuals that can withstand the prevailing conditions.
the principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to test the hypothesis, and development of a conclusion that confirms, rejects, or modifies the hypothesis.
