Flashcards in Abiotic and Biotic Factors Deck (24):
A non-living factor of the environment
A living factor of the environment
Ecosystems have three main components
1 physical surroundings
2 living organisms
3 living and non- living factors that make up the environment
What are the 6 main abiotic factors
What are the 6 biotic factors
What are the 2 factors that influence organisms
Abiotic and biotic factors
Any feature of behaviour of a plant or animal the helps it survive and reproduce in a particular way.
When 2 or more organisms rely on the same environment resource
Behaviour of one animal feeding on another
The close relationship of 2 dissimilar organisms
A symbiotic relationship where both organisms benefit
A symbiotic relationship where one organism benefits and one does not benefit but is unharmed
A symbiotic relationship where one organism benefits and one is harmed
Water- one way in which this factor can affect living organisms.
Water is essential for the chemical reactions in the cells of living things
Temperature- one way in which this factor can affect living organisms.
Heat affects the speed of chemical reactions in the cells. As the temperature increases the rate of reaction increases.
Fire- one way in which this factor can affect living organisms.
Some plants flower better after a fire and some drop their seeds.
Light- one way in which this factor can affect living organisms.
Light is necessary for photosynthesis, the process by which plants manufacture their food materials.
Soil type- one way in which this factor can affect living organisms.
Some have more nutrients for example manure and some soils hold water better than others.
Gas levels- one way in which this factor can affect living organisms.
Most organisms require oxygen for respiration. There usually enough in the air for organisms but the amount in water can change
What are the tree types of adaptations
A structural adaptations is a body part that helps an organism to survive
Behavioural adaptation is a feature is a feature of an organisms habitat, actions or way of life that helps it.
A functional adaptations is a feature of the way an organisms body works.
