A food chain is a sequence of transfer of matter and energy through food, from one organism to another. Due to the fact that most consumers in a food chain feed on more than one type of plant or animal, an intertwined network of the food chain is often found in most ecosystems. This complex …
A pyramid of numbers is a graphical representation that shows the number of organisms at each trophic level. It is an upright pyramid in light of the fact that in an ecosystem, the producers are always more in number than other trophic levels. The pyramid of numbers was advanced by Charles Elton in 1927. Charles …
Energy Pyramid is sometimes referred to as an ecological pyramid or trophic pyramid. It is a graphical representation between various organisms in an ecosystem. The pyramid is composed of several bars. Each bar has a different trophic level to represent. The order of these bars is based on who feeds on whom. It represents the …
A Food chain can be defined as the feeding relationship between the different organisms that make up our ecosystem. An ecosystem is a commune of living organisms. The ecosystem also includes the non-living components like, earth, water, fire, air and ether. The living and non-living together form the environment. Within the environment, the living or …
The physical world is composed of living and non-living things. They are generally referred to as the biotic and the abiotic. The abiotic is the physical objects like rivers, mountains, volcanoes and water-bodies. The biotic is the world of flora and fauna. Flora The word “flora” is used to designate plant life. The word “flora” …
The marine habitat destruction and loss is where the marine environment or the ecological set up is unable to support life due to degradation. This is a process that is contributed by various natural and human activities. Most countries have had the opportunity to stock marine animals and plants. Countries such as North and South …
The earth is the 3rd planet from the sun between Venus and Mars. The earth is made up of several unique properties, characteristics, composition and they all affect the processes of the earth differently. Every of these properties and elements in Earth’s system are largely categorized into one of the four major subsystems including water, …
Ecosystem is the interconnectedness of organisms including animals, plants, and microbes with each other and their non-living environment. Examples of the non-living aspects of the environment include climate, soil, water, sun, earth, rocks, atmosphere, temperature, and humidity. In an ecosystem, every living organism has an ecological niche. Hence, what makes an ecosystem is the complex …
Biomagnification stands for Biological Magnification, which means the increase of contaminated substances or toxic chemicals that take place in the food chains. These substances often arise from intoxicated or contaminated environments. The contaminants include heavy metals namely mercury, arsenic, pesticides such as DDT, and polychlorinated biphenyls (PCBs) compounds which are then taken up by organisms …
In all ecological communities, living organisms feed to get the energy that sustains their growth, movement, and reproduction. Accordingly, communities of organisms have to feed on each other creating a system whereby each organism is eaten and, in turn, it is eaten by another organism. This system is what is widely known as food chain. …
Food chain and food web represent how living organisms feed to get the energy that sustains their growth, reproduction, and movement in their respective ecological systems. It is because the various communities of organisms in an ecosystem have to feed on each other to survive. This feeding relationship in the ecosystem is thus what brings …
Forest degradation results owing to decrease in tree cover, the biodiversity in the forests or the changes to a lower state of the forest structure. Degradation refers to damage or reduction in quality of certain features of the forests. Continued degradation of the forests can destroy the entire forest cover and biodiversity, and it mainly …
Forests are our land’s trees and plants that cover a third of the earth’s surface symbolized by the color green in the common definition of environmentalism. There are many reasons why forests are an important feature for the environment and in our daily lives.They are fundamental life forms and provide for the continuity of the …
Plastic pollution poses even greater impacts on the environment because of its widespread usage and its durability component. The global plastic consumption throughout the globe was approximated at 260 million tons in 2008, and it was predicted to be more than 300 tons in 2015 – according to the Global Industry Analysts. These plastics wind …
Water is one of the most utilized natural resources by humans, animals, and plants for survival. On this regard, pollution of water threatens the survival of humans, animals, and plants. Aquatic life is even more threatened when the waters are polluted. The consequences can be disastrous depending on the degree of the pollutants concentrations, the …
