4.7.1.2 Abiotic Factors Flashcards
1
Q
What is an abiotic factor?
A
- non-living factor
2
Q
What are abiotic factors which can affect a community?
A
- light intensity
- temperature
- moisture levels
- soil pH and mineral content
- wind intensity and direction
- carbon dioxide levels for plants
- oxygen levels for aquatic animals
3
Q
How can light intensity affect a community?
A
- light is required for photosynthesis
- rate of photosynthesis affects rate of growth
- plants can be food sources or shelter for other organisms
4
Q
How can temperature affect a community?
A
- temperature affects rate of photosynthesis
5
Q
How can moisture levels affect a community?
A
- both plants and animals need water to survive
6
Q
How can soil pH and mineral content affect a community?
A
- soil pH affects rate of decay so how fast mineral ions return to soil (taken up by other plants)
- different species of plants thrive in different nutrient concentration levels
7
Q
How can wind intensity and direction affect a community?
A
- wind affects rate of transpiration
- transpiration affect temperature of plant and rate of photosynthesis
8
Q
How can carbon dioxide levels for plants affect a community?
A
- carbon dioxide affects rate of photosynthesis
- affects distribution of organisms as some thrive in high concentration levels
9
Q
How can oxygen levels for aquatic animals affect a community?
A
- levels in water vary greatly unlike in air
- most fish need high concentration of oxygen to survive
