The experts on ecology are called ecologist.

The nature’s “house” come in many sizes, from single cells to the entire planet. The largest of these houses is known as Biosphere.

LEVELS OF ORGANIZATION

There are six levels:1. Individual.2. Population.3. Community.4. Ecosystem.5. Biome.6. Biosphere.

1. INDIVIDUALS:

The individual is a specie that they can breed and produce their offspring.

2. Population:Population are the groups

of individuals that belongs tothe same species and live inthe same area.

3.COMMUNITIES:

Assemblages of different populations that live together in defined area.

4.Ecosystem: Is a collection of all organisms that

lives in a particular place together with their non-living or physical environment.

5.BIOMES:

Large systems called biomes. Biome is a groupe of ecosystems that

have the same clinical and similar dominant communities.

6.Biosphere:Contains the combine portion of the planet

in which all organisms exist, including land water and air or atmosphere.

BRANCHES OF ECOLOGY:

There are a lot of branches of ecology but here we will discuss a few which are as following:

study how the plants grow and produce.

Animal ecology:Study of the animals and their

communities.

CONTINUE…

Human ecology:In this branch of ecology we study about

how people relate to each other and as well as to the environment.

Applied ecology:The use of ecological principals to solve

the real world problems.

CONTINUE…

Medical ecology:Study about the public’s health according

to their environmental aspects. Ecophysiology:The study about the interaction of living

organisms with nonliving environment.

CONTINUE…

Functional ecology:The study about the species that play

role in the ecosystem. Fire ecology:The study about the role of fire in the

environment of animal and plants and as well as it’s effect on the ecological communities.
