Ecosystem
Ecology
All living organism, whether plant or animal or
human being is surrounded by the environment, on which
it derive its needs for its survival.
Each living component interacts with non –living
components for their basic requirements form different
ecosystem.
Definition
Ecology is the study of interactions among organism
or group of organisms with their environment. The
, environment consists of both biotic components (living
organisms) and abiotic components (non – living organisms).
or Ecology is the study of ecosystems.
Ecosystem is the basic functional unit of ecology. The term
ecosystem is coined form a Greek word meaning study of
home.
Definition
A group of organisms interacting among themselves
and with environment is known as ecosystem. Thus an
ecosystem is a community of different species interacting with
one another and with their non living environment and one
another and with their non- living environment exchanging
energy and matter.
Example
,Animals cannot synthesis their either directly or indirectly.
food depend on the plants directly but
Classification of Ecology
• Based on study area :
1. Autecology : It deals with the study of an individual species
of organisms and it’s population. The ecologists study the
behavior and adaptations of particular species to the
environmental condition at every stage of that individual’s
life cycle. It is also called the Species ecology.
2. Synecology : It deals with the study of communities, their
composition, their behavior and relation with the
environment. It is also called as Ecology of communities. It is
further divided into 3 types : 1) Population Ecology 2)
Community Ecology
, 3) Ecosystem Ecology

2. Based on Environment or habitat
1) Aquatic ecology : The study of interaction of organisms in the water
