Biotic and Abiotic Components in Ecosystems
Std. VI Science
LN. 1 OUR ENVIRONMENT
BIOTIC & ABIOTIC
COMPONENTS
DEFINATIONS
Plants and animals including human
beings ,form the living component which
are known as
biotic component
.
Air ,water,soil,light,temperature,etc. are
non-living which are known as
abiotic
component
.
ABIOTIC
COMPONENTS
DEFINATIONS
AUTOTROPHS
The green plants
which prepare
their own food are
called producers
or autotrophs.
HETEROTROPHS
Animals cannot
prepare their own
food , so they
depend on plants
for their food. They
are called
consumers or
heterotrophs.
DECOMPOSERS
& SCAVENGERS
The organism which derive their food
from dead and decaying plants and
animals are called decomposers.
Eg.Bacteria & Fungi
.
Animals and birds, jackal, crows etc.
consume dead bodies of animals to
keep the environment clean. They are
called scavengers
.
ACT. 1
BIODEGRADABLE
MATERIALS
The materials which
can be broken down
into simpler
substances by micro-
organism are called
biodegradable
materials. Eg. Paper ,
cloth etc.
NON-
BIODEGRADABLE
MATERIALS
The materials which
cannot be broken
down into simpler
substances are called
non-biodegradable
materials. Eg.
Polythene,plastic etc.
ACT.3
ACT. 5
THE MINERAL CYCLE
The cycling of the materials
through biotic and abiotic
components is called mineral
cycle.
OBJECTIVE TYPE QUESTIONS
(Carbohydrate)
1. What are the two components of our environment ?
Ans. Biotic Component and Abiotic Component.
2. Define Biotic Component.
Ans. Plants and animals including human beings form the living components i.e; Biotic
Components.
3. Define Abiotic Component.
Ans. Air , water, soil , light, temperature etc. form the non-living components i.e;Abiotic
Component.
4. Name the process of preparing food by the plants.
Ans. The process of preparing food by the plants is called Photosynthesis.
5. Write the equation of Photosynthesis.
Ans. Carbondioxide + Water
sunlight /chlorophyll
Glucose + Oxygen
6. Define Producers or Autotrophs.
Ans. The green plants which prepare their own food are called producers or
autotrophs.
7. Define Consumers or Heterotrophs.
Ans. Animals that cannot prepare their own food and are dependent on producers are
called Consumers or Heterotrophs.
8. Define decomposers.
Ans. The organism which derive their food from dead and decaying plants and animals
are called decomposers.
9. Define Micro-Organism.
Ans. The organism like fungi and bacteria that help in decomposition and are not seen
with the naked eyes are called micro-organism.
10. Define Scavengers.
Ans. Animals and birds, like jackals,crow ,vulture etc. that consume the dead bodies of
animals and keeps the environment clean are called scavengers.
11. Define Biodegradable materials.
Ans. The materials like paper and cloth which can be broken down into simpler
substances by micro-organisms are called biodegradable materials.
12. Define Non-Biodegradable materials.
Ans. The materials like plastic,polythene etc. which cannot be broken down by micro-
organism are called Non-biodegradable materials.
13. Name the scientific name of Morning Glory.
Ans. The scientific name of Morning Glory is Ipomoea.
14. Define Mineral Cycle.
Ans. The cycling of materials between biotic and abiotic components is called the
mineral cycle.
Explore the relationship between biotic (living) and abiotic (non-living) components in ecosystems. Learn about the roles of plants, animals, decomposers, and scavengers. Discover the importance of biodegradable and non-biodegradable materials in the environment.
