Sunlight is important to plant life. Plants are primary producers, so they convert energy from the sun into chemical energy and create the sugar glucose through photosynthesis.

Moisture in a biome is more than just the amount of rainfall and other forms of precipitation. Moisture is the available water present in a terrestrial biome. Because living cells are made of over 90% water and because living things constantly lose water to the environment by eliminating waste, exhaling (animals), and transpiration (evaporation of water from leaves), water must constantly be replaced.

Temperature is important to the survival of an organism. On the most basic level, this is because each organism can only survive in a specific range of temperatures. The reactions that make life possible in your cells can only occur, for example, if your body temperature is about 98.6 degrees F.

Wind is also an important part of an area's climate. Think about the effects of wind in your own ecosystem. The same wind that causes you to put on a jacket can blow a flock of birds several hundred miles from their normal migration path. Wind also has a large influence on the amount of moisture and an area's temperature.
