Light
- Solar radiation is the fundamental basis of photosynthesis and in the absence of light, even of a dense forest, the number of species is when it is in poor supply as on the floor of a dense forest, the number of species is restricted.
- Short wave solar radiation reaching the earth's surface not only determines gross patterns of energy exchange within the biosphere, but certain of its components are also responsible on a more local scale for imposing limits to organic growth.
- Quantity and quality of light are important, together with the day length and photoperiod.
- Light intensity is greatest at the equator
- Quality of light varies according to the intercepting surface (vegetation canopies)
- Light is one of the factors that determine shape, size of plants, suppression. Competition for light dominates the competition for plant survival. Root development and seedling development also determine the growth of plants.
Temperature
There are large differences in temperature across earth's surface due to:
- Variation in the quantity of incoming radiation.
- The unequal distribution of land and sea since the land is subject to a greater temperature range than the ocean.
Variations in absolute temperature, which influence the physiological functions of plants and animals, is in most cases a result of latitude, altitude and distance from seal.
