3. Effects of
Changes in
Abiotic
Factors on
the
Ecosystem

4.  The environment is a collection of living
and non-living things. Mosses growing on
rocks, garden snails, gliding on garden
fences, and fish swimming in water are just
a few examples of how living and non-living
things interact. The components of the
environment are also called organisms in
which comprise the biotic factors of an
ecosystem. The non-living components
make up the physical environment of these
organisms in which comprises the abiotic
factors of an ecosystem.

6.  Abiotic factors have a significant influence
on living organisms. It can help determine
things like how the trees grow tall, where
animals and plants are nesting, and why
birds migrate to different places. Water,
sunlight, oxygen, soil, and temperature are
the most important abiotic factors.

7.  The living parts of an ecosystem are called
“biotic factors” (McLaughlin, 2020). Biotic
factors are plants and animals and other
living things in an ecosystem. In many
ways, these living things interact with one
another. Biotic factors’ interactions can be
broken down into three groups such as
producers, consumers and decomposers.

8.  When abiotic factors in an ecosystem
change, what possibly could happen? It can
have drastic effects. Changes in abiotic
factors may result in extreme problems for
a few organisms. For example, if a plant is
tailored to low temperatures and therefore
the specific area where it lives, features a
change in its temperature due to global
warming, this plant will die and this area
will no longer support life.

9.  It can also have positive effect on
organisms. For example, several reasons
(like water pollution), water becomes rich
in mineral, thus supporting large population
of algae, causing algal bloom. Algae have a
positive effect on this alteration in abiotic
factors (water) but it does have negative
effect on plants, fish and other organisms
in water. (Shahzada, 2016).

10. A plant from Mambukal that grows better in a
low temperature environment was cultivated
and was brought to the city experiences
sudden temperature change.
1. What will happen to the plant?

11. Rosa buys a cactus plant, cactuses does not need
much water to grow and needs a lot of sunlight as it
normally found growing at the dessert.
What will happen to the cactus of Rosa if she did the
following, explain why.
1. Give it too much water.
2. Put it inside the refrigerator.
3. Expose it to the sun receiving enough amount of
water.
