Limiting factors
- Abiotic factors, non-living part of the environment
- Biotic factors, acivities of organisms and include, competition and predation.
Abiotic factors
- Temperature, the lower the temp the more slowly the population grows because there is a slower metabolic rate. at a high temp enzymes can denature and work less efficiently.
- light, ultimate source of energy for ecosystems, photosynthesis increases as light intensity increases, the greater the rate of photosynthesis, the faster plants grow and the more spores or seeds they produce.
-pH,action of enzymes
- water and humidity, populations are small where water is scarce. Humidity affects transpiration rates in plants.
