In most cases, the two major climatic factors affecting the distribution of organisms in terrestrial ecosystems are _____. water and temperature wind and water predators and parasites temperature and sunlight.

Answer 1

Water and temperature

Step-by-step explanation:

Water and temperature are the two most important factors that regulate the distribution of organisms in terrestrial habitats. Water is required for survival by living beings. The availability of water is limited in many habitats such as desert habitats. In such land habitats with water scarcity, the organisms adapted to withstand the limited water availability are found.

Likewise, temperature also affects the distribution of organisms in terrestrial habitats. The presence of temperature conditions below and above the tolerance range of the organisms restricts their geographical distribution. Temperature regulates the enzyme kinetics. Metabolic pathways are catalyzed by enzymes that function under optimal temperature conditions only. Water serves as a medium for metabolic reactions and also regulates body temperature.
