What is an ecosystem?Ecosystem is a system formed by the interaction of living organisms with one another and with their environment.

ECOSYSTEM
Abiotic components The non- living components in the ecosystem
such as air, water, soil, temperature and light
intensity. Biotic components The living components in the ecosystem
such as plants and animals.

pH
Most organism live in natural and nearly neutral environmental (pH 6 – pH 7.5).
Some plants, like maize, grows well in an acidic condition while coconuts grow well in alkaline condition.

Temperature
Effect on biochemical reaction in the organism.
Organism can live within certain range of temperature.
Poikilotherms – are animal that cannot control their body temperature.
Homoiotherms – are animal that able to maintain their body temperature.

Light Intensity
Effect the rate of photosynthesis.The distribution of green plants will be more
extensive in the area eith higher light intensity.

Humidity
Organism that can control the rate of water loss have and extensive distribution.
Organism such as frogs, snails, earthworm and moss cannot control the rate of water loss and more suited to live in damp places.

Topography
Altitude – There are less organism at high altitude because of temperature, humidity and air pressure are low.
Gradient / Slope

Microclimate
Microclimate refers to the climate of specific region in an habitat.
Microclimate includes light intensity, amount of rainfall, temperature changes and humidity of a microhabitat.

Producers
A basis producer to the primary consumers such as plants.

Consumers
An organism that feed on plants or other organism.Consumers divide into : primary consumers – herbivors that feed on plants
directly. Secondary consumers – carnivores that feed on
primary consumers directly.
Tertiary consumers – carnivores or omnivores that feed on secondary consumer.
