Everything
which is present in the surrounding of a living organism is called its environment.
Ecosystem is the study of relationship of living organisms with
their environment.
Ecology is the study of relationship of living organisms with
their environment.
Ecology is also called as environmental biology.
Ecosystem is the basic functional unit of environment.
Ecosystem is the basic unit of ecology.
Ecosystem is
always composed of two components.1)Biotic component 2) Abiotic
component
Biotic component: Those components which include all living
organisms present in the ecosystem i.e. animals and
plants.
Abiotic component: Those components which include all nonliving
materials present in the ecosystem like water, soil, light, air,
wind etc.
Ecosystem works by constant exchange of materials
between its biotic and abiotic components.
Biotic components can be dividing in to producers, consumer
and decomposers.
All the green plants are producers.
Animals are called consumers.
Microorganisms like bacteria and fungi
are called decomposers.
Those animals which directly feed on plants are
called herbivores (primary consumer). Example cow, goat, rabbit,
deer, elephant, etc.
Those animals which eat flesh of herbivores are
called carnivores (secondary consumer). Example lion, tiger,
spider etc.
Those animals which feed on secondary consumer are
called omnivores (tertiary consumers) Example sparrow, human
being, bear etc.
In an ecosystem many animals and plants live together. The actual place where
they live is called their habitat.
Those animals which active during daylight are called Diurnal
animals.
Those animals which active during at night are called Nocturnal
animals.
Sunlight is absorbed by producers (plants) and they make food for
the whole ecosystem. Then this energy is transferred to animals
(consumers) and finally decomposer releases this energy
by decomposing the dead organism. This flow of energy
is called food cycle.
The place of an organism in the food chain is called trophic
level.
The combination
of many food chains is called a food web.
Tundra is an environment that is very cold
and windy.
Tundra environment istreeless.
An adaptation is a way through which an animal’s body helps it to
survive or live in its environment.
Migration is the
movement of animals to far-away places.
Hibernationis a state of
inactivity in animals during winter season.
Aestivation is similar to hibernation but occurs in some animals
during summer or dry period.
Camouflage is a way of concealing when an animal blends with its
surrounding environment to help it to hide.
