5 limiting factors in an ecosystem include light, water, nutrients or minerals, oxygen, the ability of an ecosystem to recycle nutrients and/or waste, disease and/or parasites, temperature, space, and predation.

Photosynthesis is a process by which plants prepare their own food in the presence of water, chlorophyll, sunlight, and CO2. There are several factors affecting photosynthesis- its rate and efficiency.

Light intensity is limiting the rate of photosynthesis at light intensities of 0 to 3.75 units. As light intensity is increased the rate of photosynthesis increases.

Water is not generally considered a limiting factor because the amount needed is very small. However, lack of water can cause the plant's stomata to close, which restricts its intake of carbon dioxide.

lower carbon dioxide concentrations is the limiting factor because an increase in carbon dioxide causes an increase in photosynthesis. Intensity of light Higher CO2 concentration; higher temperature. Higher CO2 concentration; lower temperature.

For both light intensity and temperature, if the level is too low or too high, the rate of photosynthesis declines rapidly. If the temperature reaches extremely high levels, it can even denature the enzymes necessary for the chemical reactions.

When one of these nutrients is missing or in short supply, it is considered a limiting nutrient. Phosphorous and nitrogen are usually limiting nutrients because plants require large amounts of them on a daily basis.

Optimum levels of oxygen are favourable for photosynthesis. Oxygen is needed for photorespiration in C3 plants and the by-product of photorespiration is CO2 which is essential for photosynthesis.

A predator or parasites can be a limiting factor for a population of prey. Limiting factors are very important to keep populations from destroying an environment.
