Ecosystem: Structure, function, productivity, energy flow

A sudden rise or aggregation in the population of algae in freshwater or marine water systems is known as an algal bloom. The colouring in the water is mainly caused by the algae’s colours is a common indicator. Algae refers to a wide range of aquatic photosynthetic organisms, including both macroscopic multicellular creatures such as […]

Water resources refers to natural resources of water that are potentially useful as a source of water supply. About 97% of the water on the Earth is mainly salt water and only around 3% is fresh water; approximately around two thirds of this is frozen in glaciers and polar ice caps. The remaining unfrozen freshwater

Introduction of Waste Disposal In developed countries, municipal liquid waste is channelled through sewage systems and treated as wastewater or sewage. This procedure removes most or all contaminants from wastewater before it enters groundwater aquifers or surface waters such as rivers, lakes, estuaries, and seas. (For more information on sewage systems and treatment, see wastewater

Biodiversity may be defined as the variety and richness in which life presents on the earth. It refers to the diversity in all species such as plants, animals and microorganisms. Since all species in an ecosystem are interrelated and dependent on one another, biodiversity has enormous value in the lives of all organisms, particularly for

Water is essential for the life of both plants and animals. We shall talk about the importance of water in our daily life in this essay. Water is utilised in everyday life for industrial manufacturing, cleaning, hydroelectric power generation, transportation, and other purposes. Water and water resources are critical for us to maintain a sufficient food

Introduction Clean energy is defined as energy that is derived from renewable, zero-emission sources that, when utilised, do not pollute the environment, as well as the energy that is conserved through energy efficiency techniques. Functions of clean energy Using clean energy means generating electricity without causing harmful environmental consequences, such as the emission of greenhouse

The overall goal of this page is to provide information on the different types of water flow. The hydrologic cycle is the continuous circulation of water on Earth’s surface caused by precipitation, evaporation and transpiration, among other processes. Runoff from rivers and streams is the most active landscape-changing factor on the planet’s surface. Streams are

The environment is our immediate surroundings, which include both living and non-living elements. It can refer to the social, natural, or constructed environment. The environment has a significant influence on a person’s behaviour and cognition. Any change in a living entity is tied to a change in his immediate surroundings, whether directly or indirectly. Environment

An ecological pyramid (also known as a trophic pyramid, Estonian pyramid, energy pyramid, or food pyramid) is a graphical representation of the biomass or bio productivity at each trophic level in a given ecosystem. A biomass pyramid shows how much biomass (the amount of living or organic matter present in an organism) is present in

In contrast to land-based terrestrial ecosystems, aquatic ecosystems are found in and around bodies of water, rather than on the land itself. Aquatic ecosystems are made up of groups of organisms that depend on each other and their environment. Terrestrial ecosystems are ecosystems that only live on land, like tropical rainforests, deserts, grasslands, deciduous forests,
