Ecosystem Components Overview

The document discusses the two main components of an ecosystem: 1) Structural components include biotic factors like producers, consumers, and decomposers as well as abiotic factors like physical and chemical elements. 2) Functional components include interactions like food chains and food webs as well as biogeochemical cycles.

Abiotic Components

1. Physical : Factors like rain, temperature, light


etc.

2. Inorganic substances : Water, minerals and


gases.

3. Organic substances : Carbohydrates,


proteins, lipids etc.
Biotic Components

 It includes living organisms like plants, animals,


microorganisms.
1. Producers or Autotrophs
2. Consumers or Hetrotrophs
 Primary consumers (Herbivores)
 Secondary consumers (Primary carnivores)
 Tertiary consumers
 Quaternary consumers
 Omnivores
 Predator
3. Decomposers or Reducers
Producers or Autotrophs

 Organisms that produce their own food from an


energy source, such as the sun, and inorganic
compounds.
Consumers or Hetrotrophs

 Animals which are not able to produce their own


food because of the lack of chlorophyll are
included in this category.
1. Primary consumers :
 Animals which feed on plants are called
primary consumers.
 E.g. Rabbit, Deer, Goat etc.
2. Secondary consumers :
 The animals which feed on
herbivores(primary consumers) are called
secondary consumers.
 E.g. Cats, Foxes, Snakes etc.
Tertiary consumers :
 These are the large carnivores which feed on
secondary consumers are called tertiary
consumers.
 E.g. Wolves.
4. Quaternary consumers :
 These are largest carnivore which feed on the
tertiary consumers and are not eaten up by
any other animals.
 E.g. Lions and tigers
o Omnivores : Eaters of everything.
o Predators : Eat another animals by
hunting.
Decomposers or Reducers

 They breakdown the dead organic materials of


producers (plants) and consumers (animals) for
their food and release to the environment.
