Food Chain is the sequence of populations of an ecosystem which allows food and energy to go through it in a specified direction. Those on the lower end of chain become food for the ones who are on upper end. The one who is at ...

These are defined as a step of food chains which are differentiated on the basis of their method to obtain the food. The number of steps of food chain corresponds to the trophic levels. It mainly consists of the producers and consumers. Almost all trophic ...

There are a lot of differences between an autotrophs and heterotrophs. The autotrophs have the ability to manufacture their own food from the inorganic raw materials. They extract them from the outside source. They reside on the inorganic medium and require an external source of ...

The ecosystem is affected by the winds also. The winds are also known as air currents. The most of gymnosperms are pollinated by the wind and this phenomenon is known as anemophily. The wind also helps in the dispersal of seeds, fruits, cysts and many ...

The intensity, quality and the duration of light play an important role for the survival of organism. The organisms have photoreceptors. The light may lead to many processes. The photosynthesis is performed by the autotrophs. It provides food to plants as well as animals. Light ...

The temperature with a narrow range allows the organism to survive. It varies from 5 to 35 degree Celsius. There is an exception for spores, seeds and some other organisms. The prokaryotes occur in the high temperatures of hot spring and in the low temperatures ...

The ecosystem consists of two components which are known as the biotic and abiotic. The biotic component includes the autotrophs, heterotrophs and the reducers. They form the living members of an ecosystem. These components are related by the food mainly. The food transfers the matter ...

It is also known as a biological equilibrium. This is also referred as a balance of nature. An ecosystem maintains a biological equilibrium between the different components and is referred as a homeostasis. It keeps on changing with the time and is not static. The ...
