Importance of Ecology

Importance of Ecology

The following reasons explain the importance of ecology:

Conservation of Environment

Ecology helps us to understand how our actions affect the environment. It shows the individuals the extent of damage we cause to the environment.

Lack of understanding of ecology has led to the degradation of land and the environment. It has also led to the extinction and endangerment of certain species. For eg., dinosaurs, white shark, mammoths, etc. Thus, the study of the environment and organisms helps us to protect them from any damage and danger.

Resource Allocation

With the knowledge of ecology, we are able to know which resources are necessary for the survival of different organisms. Lack of ecological knowledge has led to scarcity and deprivation of these resources, leading to competition.

Energy Conservation

All organisms require energy for their growth and development. Lack of ecological understanding leads to the over-exploitation of energy resources such as light, nutrition, and radiation, leading to its depletion.

Proper knowledge of ecological requirements prevents the unnecessary wastage of energy resources, thereby, conserving energy for future purposes.


Ecology encourages harmonious living within the species and the adoption of a lifestyle that protects the ecology of life.

Examples of Ecology

Following are a few examples of ecology:

Human Ecology

It focuses on the relationship between humans and the environment. It emphasizes the impact human beings have on the environment and gives knowledge on how we can improve ourselves for the betterment of humans and the environment.

Niche Construction

It deals with the study of how organisms alter the environment for the benefit of themselves and other living beings. For eg, termites create a 6 feet tall mound and at the same time feed and protect their entire population.

Frequently Asked Questions

What is ecology?

Ecology is the branch of science that deals with the relationship of organisms with one another and with their physical surroundings.

What are the different levels of ecology?

The different levels of ecology include- organisms, communities, population and ecosystem.


What are the different types of ecology?

The different types of ecology include- molecular ecology, organismal ecology, population ecology, community ecology, global ecology, landscape ecology and ecosystem ecology.


How are ecology and evolution related?

Ecology plays a significant role in forming new species and modifying the existing ones. Natural selection is one of the many factors that influence evolutionary change.


Who devised the word ecology?

Ecology was first devised by Ernst Haeckel, a German Zoologist. However, ecology has its origins in other sciences such as geology, biology, and evolution among others.


What is habitat ecology?

Habitat ecology is the type of natural environment in which a particular species of an organism live, characterized by both physical and biological features.


What is a niche?

An organism free from the interference of other species and can use a full range of biotic and abiotic resources in which it can survive and reproduce is known as its fundamental niche.
