The document discusses abiotic components of ecosystems, including factors like temperature, humidity, altitude, and soil pH, and their effects on organisms. It highlights the differences between poikilotherms and homoiotherms in temperature regulation and explains how microclimates influence the distribution of organisms. Additionally, it notes that certain plants thrive in specific pH levels, and that aspects of topography affect soil erosion and water flow, impacting habitat suitability for various species.

2. The non-living components
ABIOTIC COMPONENTS
in the ecosystem such as
(physical factor)
air, water, soil temperature
and light intensity

3. Light Humidity

Gradient/Slope
Aspect

4. pH VALUE
Most organisms live in a neutral or nearly
neutral environment.
Some plants, like maize, grows well in an
acidic condition.
while coconuts grow well in an alkaline
condition.

5. TEMPERATURE
POIKILOTHERMS
- Are animals that cannot control their body
temperature with the environmental
temperature.
HOMOITHERMS
- Are animals that can maintain their body
temperature

7. HUMIDITY
The amount of water vapour present in the air.
The humidity of air affects the rate of water loss
by plants and animals.
When humidity is low, water evaporates from the
moist surfaces at a faster rates.
Humidity is usually higher at night but lower
during the day.
Organisms such as frogs, snails, earthworms and
moss that cannot control the rate of water loss
are more suited to live in damp places.

8. Altitude
-There are less organisms at high altitudes because
temperature, atmospheric pressure an air humidity are law.
-Different plants are found at different altitudes.
Gradient/slope
-The gradient of a place affects the rate of water flow.
-In steep areas, the swift flow of water causes soil erosion while in flat
areas, the water is stagnant.(these 2 areas are not suitable for plants and
animals to live)
Aspect
-Aspect refers to the direction facing or opposing the wind and sunlight.
-Areas facing aspects are not suitable for living and hence, have less
organisms.

9. MICROCLIMATE
Refers to the climate in a microhabitat.
Microclimate includes humidity, light
intensity and atmospheric conditions in which the
organisms live.
Influences the number and distribution of
organisms.
