Abiotic = non-living factors
e.g. sunlight, temperature, wind direction and strength
Biotic = factors caused by the presence or role of other living things
e.g. interaction of plants with insects in their environment

4. Non-living parts of your community (Abiotic)
Buildings
Roads
Bodies of water
Land
Wind
Sunlight

5. Abiotic factors affect distribution of species
                        Abiotic factors of interest include:
                                   
- Temperature (range from 0 to 45 C)
- Water
- Sunlight
- Wind (increases heat & water loss)
Rocks and soil
Amount of oxygen in the water

For ex: Long-lived and healthy wetlands and forests are examples of sustainable biological systems.

8. SILENCE OF THE FROGS ACTIVITY
What are Endangered Species?
An endangered species is a POPULATION of organisms which are AT RISK of becoming EXTINCT because it is either few in numbers, or threatened by various factors.
Some of the factors are:
Loss of species habitat due to accommodating for growing human population
Pesticide use
Hunting and trading
Pollution

9. EXAMPLES OF ENDANGERED SPECIES:
SEA OTTER
