Pyramid of Biomass: Definition and Examples

Pyramid of Biomass: Definition and Examples

A pyramid of biomass is a graphical representation of biomass present in a unit area of various trophic levels. It shows the relationship between biomass and trophic level quantifying the biomass available in each trophic level of an energy community at a given time. There are two main types of biomass pyramid – inverted pyramid…

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…

Tertiary Consumer: Definition, Examples and Functions

A food chain contains several trophic levels. These trophic levels separate various types of organisms. A tertiary consumer is a fourth trophic level after producers, primary consumers, and secondary consumers. Tertiary consumers eat primary and secondary consumers as their main source of food.

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…

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…
