Ecology consists of the scientific study of the interactions between living beings and the environment in which they inhabit and also between them. Ecology is also interrelated with other sciences such as Earth sciences, geography and biology and allows us to know the way in which the environment works and how humans and other living beings depend on it.
Within ecology, there are different branches of study. In this AgroCorrn article, we explain which are the branches of ecology and what each one studies .

What is ecology
Given its scope of study, ecology can study living organisms, compare them with each other, or relate them to the components of their habitat. One of the major interests of ecology is the study of the variation, distribution and abundance of certain organisms and their relationships of collaboration or competition between them or between ecosystems . In this way, ecology is important to understand the evolution and life of our planet , more than the environment itself. The development of ecology also affects the conservation and well-being of the human being as a species.
Ecology can be studied at various levels, ranging from the individual base of each organism, to the study of ecosystems or the biosphere, passing through the population and community levels. Thus arise the different branches of ecology.
The branches of ecology and what they study
Next, we comment on each of the different branches of ecology and what each one of them studies :
Hierarchical ecology
Hierarchical ecology is responsible for studying the organization of biological beings. Hierarchical ecology analyzes the different orders in which living things are classified, from atoms to cells, their tissues, organs, organisms, populations, ecosystems and, finally, the biosphere .
Individual ecology
He studies organisms individually and also compares them with other living things to observe similarities and differences between them. In addition, it analyzes the vital traits of the species, reproductive systems, metabolic processes and other systems.
This type of ecology is responsible, for example, for determining how long a turtle lives, what its way of life is like or when it is and how long its reproductive cycle lasts.
Population ecology
This branch deals with studying the population of a species, its life cycle, its behavior and its relationships with other species. Population ecology analyzes the behavior of several species that inhabit the same habitat.
This study is carried out taking into account variables such as births, emigration, immigration and deaths. For example, this branch is the one that deals with the study of the behavior of a species of birds and with analyzing their travels at different times of the year.
Community ecology
Community ecology studies a group of species and their interactions within the same environment. For example, community ecology is the branch in charge of studying predator-prey dynamics and competition dynamics within an ecosystem. In this field enter, for example, food webs or trophic relationships .
Ecosystem ecology
Ecosystem ecology is responsible for studying the interactions between species and the ecosystem in which they live, as well as biotopes , among other related aspects. This is the branch in charge of measuring the fluxes of elements existing in nature such as phosphorus, magnesium or iron. For example, a plant that produces organic matter needs a decomposing organism , which can be a fungus or a bacterium.

Behavioral ecology
This branch of ecology studies the behavior of organisms within their habitat. For example, this branch studies behavioral characteristics such as hunting, camouflage, resting, if a species climbs or if it escapes from predators.
- Cognitive ecology: this branch studies the way in which a species perceives its environment and how the environment influences its behavior.
- Social ecology: this branch studies eusocial animal species, that is, those species that form complex societies where each individual plays a specific role for the common good, such as humans or ants. The factors studied in these societies are coexistence, the selection of links, interactions to achieve mutual benefits or survival.
- Coevolution: this branch studies the interaction between two species associated with each other for a reciprocal good. As an example, we have the association of fungi and plants in mycorrhizae, the bacteria of the human digestive system to improve digestive processes or the association between photosynthetic algae and fungi in lichens.
Molecular ecology
This branch of ecology uses advances in the fields of genetics or molecular biology to study how it relates to the environment.
biogeographic ecology
This branch of ecology studies the geographical distribution of species and how they change over time, that is, their evolution throughout their existence.
Famous ecologists
