- Abiotic and Biotic Features.
- Light Intensity
- Light limits photosynthesis so will affect the distribution of plants and animals. Some plants have more chlorophyll or bigger leaves.
- Temperature
- Is a limiting factor on photosynthsis and growth of plants. In cold climates, plants may frreeze therefore Actic plants are small.
- Moisture levels
- If there is no water there will be no life. Desert areas contain little life and when water is available they are adapted to get it.
- Soil pH and mineral content
- Some carnivorous plants thrive in areas of mineral deficiency as they are capable of gaining nitrates from dissolving animal proteins.
- The level of minerals such as nitrates have a large effect on the distribution of plants.
- Wind intensity and direction
- Areas of strong winds affect the shape of trees and can cause plants to transpire faster.
- Availability of oxygen
- This has huge effect on water-living organisms.
- Availability of Carbon Dioxide
- This is a limiting factor of photosynthesis and affects plant growth and distribution. It can also affect distribution of some organisms.
- Availability of food
- Animals may starve, it can be affected by weather or drought and can sincerely affect the food chain to the point where it cna wipe out whole species.
- New pathogens or parasites
- Diseases whereby species are not resistant can cause many people to die.
- New Predators
- New predators may cause a limited amount of the prey that they hunt. This can cause a food limitation for other predators.
- Interspecific competition
- Different species fighting for the same thing can, e.g. when trees in a forest grow taller then the shortest ones. They block out the sunlight and collect all the water.
- Light Intensity
