EFFECT OF CHANGES IN THE ABIOTIC FACTORS
ON THE ECOSYSTEM
Changes caused by natural processes and
human activities
Habitat changes can occur through natural processes or as
a result of human activities.

Natural changes to habitats can occur due to various factors. Here are some
examples of natural changes that can affect habitats:
SUCCESSION
Succession refers to the natural
changes that happen to plant and
animal communities over time.
When one group of organisms starts
growing and doing well, it creates an
environment that helps other
species thrive. This leads to changes
in how the habitat looks and how it's
organized.
ECOLOGICAL
INTERACTIONS
Organisms in a habitat can
influence each other and even
change the habitat itself. For
example, the presence of a new
predator may affect the number
of other animals called prey. The
predator may eat more of the
prey, which can cause the
population of prey to go down.
NATURAL
DISTURBANCES
Natural disturbances such
as wildfires, floods, storms,
volcanic eruptions, or
landslides
can
cause
significant changes in
habitats.
GEOLOGICAL
PROCESSES
Natural geological processes like
erosion, tectonic movements, or
the formation of new landforms
can shape habitats. For example,
the gradual deposition of
sediment can create new
habitats like wetlands.

Human-made changes to habitats refer to alterations in the natural
environment caused by human activities. Here are some examples:
HABITAT
DESTRUCTION
Deforestation, clearing land for
agriculture, urbanization, and
infrastructure development are
all human actions that destroy
habitats
and
disrupt
ecosystems.
POLLUTION
Human
activities
introduce
various forms of pollution that
can negatively impact habitats.
For example, air pollution from
industrial emissions and vehicle
exhaust can affect plant health
and contribute to the decline of
certain plant species.
OVEREXPLOITATION
OF RESOURCES
Unsustainable
practices,
such
as
overfishing,
overhunting,
and
overharvesting of resources,
can deplete populations of
species and disrupt habitats.
CLIMATE CHANGE
Human activities, like burning fossil fuels
and deforestation, are responsible for
contributing to climate change. Climate
change, in turn, can lead to changes in
temperature and rainfall patterns.
Habitats that used to be cool and wet
might become hotter and drier, while
previously dry areas may receive more
rainfall. These alterations can have an
impact on the organisms that inhabit
those habitats.
It's important for us to learn
about these natural and
human-made changes and
how they affect habitats. By
understanding and finding
ways to help, we can
protect habitats and the
organisms that depend on
them.
