Ecology question 3

Explain how limiting factors influence an organism’s distribution and range. 
E.g. 
Abiotic factors:  water, temperature, sunlight, salinity, oxygen, PH value         
Biotic factors: competitors, predators and parasites


Temperature: 
- Different temperatures can affect the growth, activities and survival of the organism.

Light: 

- Provides warmth

- Supports photosynthesis

- Enable organisms to see 

Water:
- Basic substance to survive as cells make up mostly of water

- Provides habitat for sea animals 

Air:

- Organisms need oxygen to carry out respiration.

- Plants need carbon dioxide to carry out photosynthesis.

PH value: 

- Determine types of organism living in a particular land or water


Competitors:
- More competitors
- Less food for other living organisms
- Weaker growth


Predators:
- More predators
- More organisms being eaten up
- Less number of the kind of organisms


Parasites:
- More parasites
- More living organisms suffer
- Less number of kinds of organisms
