Flashcards in Abiotic and Biotic Factors Deck (24):
1

Abiotic factors

A non-living factor of the environment

2

Biotic factor

A living factor of the environment

3

Ecosystems have three main components

1 physical surroundings
2 living organisms
3 living and non- living factors that make up the environment

4

What are the 6 main abiotic factors

Water
Temperature
Fire
Light
Soil type
Gas levels

5

What are the 6 biotic factors

Competition
Predation
Mutualism
Symbiosis
Commensalism
Parasitism

6

What are the 2 factors that influence organisms

Abiotic and biotic factors

7

Adaptations

Any feature of behaviour of a plant or animal the helps it survive and reproduce in a particular way.

8

Competition

When 2 or more organisms rely on the same environment resource

9

Predation

Behaviour of one animal feeding on another

10

Symbiosis

The close relationship of 2 dissimilar organisms

11

Mutualism

A symbiotic relationship where both organisms benefit

12

Commensalism

A symbiotic relationship where one organism benefits and one does not benefit but is unharmed

13

Parasitism

A symbiotic relationship where one organism benefits and one is harmed

14

Water- one way in which this factor can affect living organisms.

Water is essential for the chemical reactions in the cells of living things

15

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.

16

Fire- one way in which this factor can affect living organisms.

Some plants flower better after a fire and some drop their seeds.

17

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.

18

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.

19

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

20

What are the tree types of adaptations

Structural
Behavioural
Functional

21

Structural adaptations

A structural adaptations is a body part that helps an organism to survive

22

Behavioural adaptations

Behavioural adaptation is a feature is a feature of an organisms habitat, actions or way of life that helps it.

23

Functional adaptations

A functional adaptations is a feature of the way an organisms body works.

24

Ecosystem

A place where organisms and their physical surroundings from a balanced environment that is different from others near by.
