Examination.

    Ecology is the study of the relationships between living organisms, including humans, and their physical environment; it seeks to understand the vital connections between plants and animals and the world around them. Ecology also provides information about the benefits of ecosystems and how we can use Earth’s resources in ways that leave the environment healthy for future generations.

    Ecologists study these relationships among organisms and habitats of many different sizes, ranging from the study of microscopic bacteria growing in a fish tank, to the complex interactions between the thousands of plant, animal, and other communities found in a desert.

    Ecologists also study many kinds of environments. For example, ecologists may study microbes living in the soil under your feet or animals and plants in a rain forest or the ocean.

    Ecology is a  branch of science including human science, population, community, ecosystem, and biosphere. Ecology is the study of organisms, environment and how the organisms interact with each other and their environment. It is studied at various levels such as organism, population, community, biosphere, and ecosystem.

    Ecologist’s primary goal is to improve their understanding of life processes, adaptations and habitats, interactions and biodiversity of organisms.

    Let us have a detailed look at the ecology notes provided here and explore the concept of ecology.

    Biotic and Abiotic Factors

    The main aim of ecology is to understand the distribution of biotic and abiotic factors of living things in the environment. The biotic and abiotic factors include the living and non-living factors and their interaction with the environment.

    Abiotic components are non-living chemical and physical factors of an ecosystem. These components could be acquired from the atmosphere, lithosphere, and hydrosphere. A few examples of abiotic components include sunlight, soil, air, moisture minerals, and more.

    Living organisms are grouped into biotic components whereas non-living components like sunlight, water, topography are listed under abiotic components.

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

    Global Ecology

    It is the study of interactions among earth’s ecosystems, atmosphere, land, and oceans. It helps in understanding the large-scale interactions and their influence on the planet.

    Landscape Ecology

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

    Ecosystem Ecology

    It is the study of the entire ecosystem which includes the study of living and non-living components and their relationship with the environment. This science research how ecosystems work, their interactions, etc.

    Community Ecology

    It is the study of how community structure is changed 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 is the study of factors that change and impact the size and genetic composition 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 population distribution and density. Population density is the number of individuals in a given volume or area. This helps in determining whether 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 nonliving 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.
