Types, Importance and Examples of Food Chain

Types, Importance and Examples of Food Chain

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…

Pyramid of Numbers: Definition, Types and Examples

Pyramid of Numbers: Definition, Types and Examples

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: Definition, Levels and Examples

Energy Pyramid: Definition, Levels and Examples

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…

Levels, Importance and Main Components of Food Chain

Levels, Importance and Main Components of Food Chain

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…

Ecosystem – Components and Threats To an Ecosystem

Ecosystem – Components and Threats To an Ecosystem

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…

Causes, Effects and Process of Biomagnification

Causes, Effects and Process of Biomagnification

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…

Trophic Levels and Energy Flow in a Food Chain

Trophic Levels and Energy Flow in a Food Chain

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….

What is a Food Chain and What is a Food Web?

What is a Food Chain and What is a Food Web?

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…

What is Forest Degradation and What are Various Causes of it

What is Forest Degradation and What are Various Causes of it

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…
