Biotic Component

                                       Biotic Component 



Biotic component are those type of component which is consist of basically the  all living organisms  which forms ecosystem together . The word Bio means The life or living things . There are three types of Biotic Component -


  • Producers - The producer are those organism which produces food by taking energy from sun . They are also known by its another name Autotrophs . Auto - own and tropes - making .
  • Consumers - All the organisms on the earth depends upon food for their survival . The consumer are the organisms which obtain food from producer either directly or indirectly . The consumer are of three types based on habit of food - 



  1. Primary Consumers - Deer is the best example for understanding primary consumer as they get food from plants . These primary consumer forms food for other consumer known as secondary consumer .
  2. Secondary Consumers -  The secondary consumer are those organisms who eat  primary consumer as a source of food . For example cat , dog , wolf .
  3. Tertiary Consumers - The tertiary consumer are those organisms who eat secondary consumer for their food . For example lion , tiger , snake .



  • Decomposers -  The organisms which rely upon dead and decay materials are known as Decomposers . They are also called Natural  Scavengers as they are able to degrade the body of organisms .

The Significance of Food Webs for Environmental Balance | Biology Blog

                                         Food Web 

Food Web

Food web is generally a interconnection of food chain in a graphical manner to show who eat whom is called Food Web . This web shows the  description of feeding connection between the organisms . Energy is passes from one tropic level to another level by this food web links  .

For example -  A rat can feed on grains , roots , stems . A rat in turn consumed by snake which is then eaten by another organisms like eagal . The snakes can feed upon both the rat and frogs . In this way there is a connection of food chain from one another and this process is called Food Web .

Importance -  

  • Through various trophic levels, from primary producers to top predators, they offer a mechanism for the transfer of energy and nutrients.

  • Food webs are essential for population control, reducing overgrazing and resource overconsumption.

  • They can be used to track long-term changes in ecosystems and are crucial environmental health indicators. For effective resource management and conservation, food webs are essential.

Predator, Parasitic & Saprophytic Food Chain With Examples

                                            Food Chain




In our ecosystem the green plants produced some energy containing molecule as a source of food . This food is eaten by herbivorous animal like cattle , deer , goat etc  i .e they obtain energy directly from the  plants .

Food Chain Examples

This herbivorous animal is eaten by carnivorous animal like dog , lion , tiger and in this way the energy is transferred to another organism and this series is continuous through out  the life and providing raw material and energy from one to another . Such series is known as Food Chain .

The energy is transferred from one organism to another and this sequence is basically called as Food Chain.

Types - There are three types of food chain -


  • Predator Food Chain - As the name suggest in this type of food chain the predator predates its food . The herbivorous is eaten by secondary consumer and secondary consumer is eaten by tertiary consumer this is known as Predator Food Chain . You can understand by the example given here . Lets say a Grasshopper eat the plants and then grasshopper is eaten by mice . In this case Mice, is predator bcause it preys on Grasshopper . 


Food Chain Cycle
  • Parasitic Food Chain - In this type of food chain the energy is passes from larger to smaller organisms . For example the energy is passes from host to parasite . For example , a malaria parasite that enters the human's blood after the bite of an mosquito and multplies itself in the body and cause the disease Malaria . 

  • Saprophytic Food Chain - Saprophytes are those organism which eat dead and decay  organisms . There is transfer of energy from dead and decay to micro organisms . For example , in this picture , when a hawk dies then it is eaten by fungi .

Ant life cycle: stages and development | Biology Blog

                                        Ant Life Cycle

Ant

Ant is a living organism of a class of insects.  They usually prefer to live in a colony consist of a queen , female worker, and male. Only the queen has the tendency to produce eggs. The role of the female worker is to collect food and building and cleaning the nest. The female worker doesn't have wings while the queen has. The male ant also has wings that have been used to fly and reach the queen ant and mate to produce eggs. After producing egg the male ant died soon.

Life Cycle -   The life cycle of ant is consists of four stages - Eggs, Larvae, Pupae, and Adults. The whole life cycle completed in more than a week.
Ant Life Cycle


  • Egg -  The queen ant and male ant mate to produce the egg . The egg of the Ants is soft and oval in shape.
  • Larvae - After  7 - 14 days the larvae emerge from the egg. They depend upon the ants for the food to grow. They take almost 24 to 30 days for their growth.
  • Pupae -  When the larvae grow enough they change into pupae. The legs and antenna are in folded form. They start out whitish and become darker later.
  • Adult  - Taking almost 13 - 28 days the pupae converted into an adult . They are often lighter in color which becomes darker with the age.

Hydrological/ Water Cycle Steps With Diagram - BioNotes

                                           Water Cycle 



Water is  really a very  powerful factor of all ecosystem . All organisms need water for their survival and growth . Water has three phases - solid , liquid and gas . The liquid phase is important for living a life on planet and gaseous phase is important for the respiration process . Water cycle is also known by its another name" Hydrological Cycle ".

Water Cycle -   Water cycle is generally the journey of water from one place to another and from one state to another state . Their is  no end and it is a   continuous process that is why it is called "Cycle" .  Let us understand the water cycle

The sun heats the surface of earth as a result the water starts evaporating in the form of water vapor . The water vapor condense and change into liquid and  form clouds  this process is called as condensation . The water now fall from the clouds in the form of precipitation ( rain, snow  ) and collected into the water reservoir like see , ponds . lakes ,  river . Some of the water is absorbed into the earth surface as a ground water and use by plants and animal for drinking  purpose or it may be  run off from the soil and collected into the ocean  , river and lakes from where again cycle starts.


Importance of Water -


  • Water is very important for survival of living organism . without water there is no existence of life on earth .
  • Used in keeping community clean .
  • Water is very essential for crop production .
  • Water is important for the working of macro molecule as a good ionizer .

What is thundering and how it cause : Biology Blog

                                        What is Lightening 





Lightening is a hazardous phenomenon of nature. Every year it kills more than thousands of people in the world. Simply, we can say that when rain is the art of mother nature than lightening is the fireworks. It happens due to the flash of electricity which is produced by thunderstorms.

How lightening happens - Lightening happens due to the reason that when the ground becomes warm it heats the air. As the hot air rises, again and again, the water vapor melts into clouds and there is the creation of an electric charge. The positive charge present on the top of the cloud and negative charge electron present at the bottom of the clouds. At the same time object on the ground have a positive charge. When a negative charge electron from the clouds comes closer to the positive charge proton then the charge is neutralized and, there is a production of lightening which heats the surrounding air.



What are the safety measure -


  • The first important thing is whenever you hear thunder get immediate shelter. If you are outside of your home than stay away from trees, poles wire, and fences.
  • Stay away from motorcycles, scooters, and bicycles.
  • Do not use a corded phone. 
  • Avoid contact with water.
  • If you caught outside then take a ball-like position with hands tucked and your head is towards the ground.
