This document discusses the differences between abiotic and biotic components of an ecosystem. It defines abiotic components as the non-living physical and chemical factors such as air, water, soil, sunlight, and temperature. Biotic components refer to the living organisms in an ecosystem, including producers like plants that carry out photosynthesis, consumers like animals, and decomposers like bacteria and fungi. The document outlines key abiotic components and provides examples of different types of biotic components, emphasizing that biotic life depends on abiotic resources and noting the interactions between living and non-living aspects of any given ecosystem.

2. Outline
 Introduction
 Abiotic Components
 Biotic Components
 Difference between abiotic & biotic

3. Environment:- Everything surrounding us
Earth is mainly divided in 4 spheres

4. Uses of spheres

5.  There are many important components of environment but
two main components exist in an ecosystem
1. Biotic
2. Abiotic
 The Abiotic components of any ecosystem are the property
of an environment.
 The biotic components are the life forms that occupy a
given ecosystem.
 Everything that is around us it can be living or non-living
things, it includes physical, chemical and natural forces.

6.  Abiotic components are the non-living
things in an ecosystem.
 Every biotic components is in some way
dependent on abiotic components

7. Abiotic Components
 Air :-
Air plays a vital role in recycling one of Earth's most important
substances: carbon.
 Water:-
All plants and animals must have water to survive. If there was no
water there would be no life on earth.
 Soil:-
It influences the distribution of plant species and provides a habitat for
a wide range of organisms.
 Sun light:-
Without the Sun's heat and light, the Earth would be a lifeless ball of
ice-coated rock. so without sunlight life is impossible on earth.
 Temperature:-
influences the growth of many living organisms

8. Abiotic components
temperature

9.  Biotic components are all the living things in an
ecosystem
 There are different topic levels in the ecosystem
 E.g. :- green plants, animals, microorganism

10. Types of biotic components
Biotic
components
producers
E.g.
Green plants
consumers
E.g.
animals
decomposers
E.g.
Bacteria ,
fungi

11. 1.Producers (Autotrophs)
Auto :- self , troph :- Nourishment
There are two types of producers
 Photosynthesis
They use sunlight and make carbohydrates
H2O + CO2 + Sunlight C6H12O6 + O2
E.g. :- green plants ,
 Chemosynthesis
They use chemical energy and make carbohydrates
CO2 + H2O + H2S + O2 CH2O + H2 SO4
E.g. :- some bacteria

12. 2. Consumers ( Heterotrophs )
Hetero :- different , Troph :- Nourishment

13. 3. Decomposers ( detrivores )
An organism that breaks down dead organisms to get
energy.
