Types of Ecology

The diagram showing different Types of Ecology

Ecology can be classified into different types. The different types of ecology are given below:

Global Ecology

It deals with interactions among earth’s ecosystems, land, atmosphere and oceans. It helps to understand the large-scale interactions and their influence on the planet.

Landscape Ecology

It deals with the exchange of energy, materials, organisms and other products of ecosystems. Landscape ecology throws light on the role of human impacts on the landscape structures and functions.

Ecosystem Ecology

It deals with the entire ecosystem, including the study of living and non-living components and their relationship with the environment. This science researches how ecosystems work, their interactions, etc.

Community Ecology

It deals with how community structure is modified by interactions among living organisms. Ecology community is made up of two or more populations of different species living in a particular geographic area.

Population Ecology

It deals with factors that alter and impact the genetic composition and the size of the population of organisms. Ecologists are interested in fluctuations in the size of a population, the growth of a population and any other interactions with the population.

In biology, a population can be defined as a set of individuals of the same species living in a given place at a given time. Births and immigration are the main factors that increase the population and death and emigration are the main factors that decrease the population.

Population ecology examines the population distribution and density. Population density is the number of individuals in a given volume or area. This helps in determining whether a particular species is in endanger or its number is to be controlled and resources to be replenished.

Organismal Ecology

Organismal ecology is the study of an individual organism’s behaviour, morphology, physiology, etc. in response to environmental challenges. It looks at how individual organisms interact with biotic and abiotic components. Ecologists research how organisms are adapted to these non-living and living components of their surroundings.

Individual species are related to various adaptations like physiological adaptation,  morphological adaptation, and behavioural adaptation.

Molecular Ecology

The study of ecology focuses on the production of proteins and how these proteins affect the organisms and their environment. This happens at the molecular level.

DNA forms the proteins that interact with each other and the environment. These interactions give rise to some complex organisms.
