Ecosystem is the interaction between all living things
and non-living things in a region or community. 1It’s a system where living things and non-living
things interact and depend on each other. It’s the relationship between
organism and their physical environment, between organism of the same species
and of different species. 2Ecosystem
influences plant productivity, environmental conditions and also human welfare
the ecosystem processes are also controlled by both plants and animals and
microbes living within the a community every organism contributes to the
ecosystem. 3 he ecosystem relationship is very complex, it’s the basis of
life itself it’s structured it functions through several biochemical cycles,
energy transfer mechanism and other components that consists of biotic living and
abiotic non-living things. 1they
interact through functional aspects to form natures ecosystem which includes
energy cycles, renewable and nonrenewable energy, forming the food chain, web
of life which man depends on, water cycle, natural resources and nutrients
tends to change over period of time, gradual changes through orderly process
like change in climate and also human activity, human activity can also affect
natural ecosystem causing global warming that affect the climate and alter
ecological functions and life support that are vital to the wellbeing of all
living things, this disruption of
natural ecosystem cycle can lead to an extinction of some species of plant and
animals, the elimination of some of these plants, animals can seriously affect
the natural ecosystem. 1The ecosystem is divided into terrestrial and aquatic
ecosystem; these are the two major habitats for all living organisms, Plants
and animals and the non-living things of the ecosystem are air, temperature, sunlight,
water, soil, various inorganic substance and organic substance, climatic conditions
which depends on geographical conditions and location.
The major ecosystems for all livings things are the
terrestrial ecosystem e.g. tropical rainforest, savanna, grassland, tundra,
swamp, mountains, deserts, and aquatic ecosystem e.g. fresh water, ponds,
rivers, wetlands, lakes, ocean. 3 These ecosystems differ in relation due to their
geographical region in which they exist.
They regions where organisms e.g.
plants, animals, man live and survive unlike the aquatic ecosystems the terrestrial
ecosystems present much more characteristics due to its numerous factor
conditions, availability of water, nutrients and light, vegetation.3 There are
different types of terrestrial ecosystem
Tropical rainforest this region have many different animals and plants that all live in a
very small and this result to an extremely dense ecosystem. 3 The light and temperature in this
terrestrial ecosystem remain the same throughout the year.
Temperate forest, they exist in places that have summers and winters, and the trees
loss their leaves in winters, for example trees like mosses and ferns.
Desert they occupy about 17% of all land in the planet, they are found in
regions with less rainfall. 3 They have low water availability due to high
temperatures and intense sunlight, few plants that sustain water grows there.
Savanna they have individual trees and they are dry, but they support a large
number of predators and herbivores.
Terrestrial habitat, here land is
used intensively, the sustainable natural resources of environmental goods e.g. 1 soil, water, timber from forest, grasses and
herbs from grassland for grazing and unsustainable natural resources the
overuse and misuse of natural resources
can lead to degradation of the environment.
ecosystem consistent of the marine environments of the sea fresh water, lakes,
ponds, rivers, wetlands and has plants and animals that live in the water. 1 Organism
that live in water they have physical characteristic that are suitable for them
to survive in the water. This ecosystem is the largest because they represent 75 % in the
entire ecosystem geographical areas. 3 Aquatic ecosystem have different organism,
which makes the ecosystem of the aquatic life to be divided into different
Wetlands are flat lands that have groundwater of shallow depth e.g. swamps
Lake a giant permanent pond formed from underground water flow natural
accumulation of fresh water.
Rivers and Streams are flowing water, are accumulation of runoff
and underground water.
The ecosystem is the community of biological
organism where they interact with physical environment, all the living organism
