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 .

                                     Canal system in Sycon  A sea creature called a sycon, or scypha , is usually found clinging to rocks or other surfaces. These creatures have tube-shaped bodies that open outward with the help of a hole called an Osculum . They have tiny openings called Spiracles and Ostia all over their bodies to let water in. This water flows through canals inside their bodies and comes out through the Osculum, which is a larger opening used for breathing. We'll observe the shape of this canal system, why it is essential for those animals, type of canal system , and  its significance. The Sycon Type Canal system is the unique feature of the phylum Porifera . This system is also known as the  aquiferous canal system . This system supports the significant function of the body like nutrition, respiration, excretion, etc. History Overview -  Grant, a scientist from Scotland, spent a lot of time studying sponges. He was one of the first to really explain how t

                                             Aurelia  Aurelia aurita is a type of zooplankton found all over the world. They are see-through and don't have eyes, brains, or hearts. They're usually between 2 to 15 inches wide. Even though they prefer being alone, they get carried together in groups called Blooms by wind and water currents. At night, they look like they're moving through the water like jellyfish, which is why they're sometimes called " jellyfish ".  They have four reproductive organs surrounded by tentacles in their top part. Their body color changes based on what they eat, so they can be blue, pink, or other colors. Let's learn more about Aurelia in detail. Details Of Aurelia Diagram -  Body : The center of the diagram would display the jellyfish's bell-shaped body, often called the " umbrella. " Tentacles : Below the bell, you'd see long, hair-like tentacles extending outward. Oral Arms : The oral arms are  used for

                                             Types of Egg Hello guys! We'll examine a crucial area of zoology in this blog: different varieties of eggs. So let's define reproduction first before moving on to the subject. Reproduction is the biological process in which a parent is responsible to produce their offsprings which may be of their own kind. Reproduction is a must process for every individual for the continuing existence of the species. As we all know, there are many different species on the planet, and each of them has a unique method of egg production and inside the egg they contain yolk . The yolk is composed of proteins, fats, vitamins, and minerals, which are vital for the growth and development of the embryo.  Eggs can be classified into different types based on the amount of yolk they contain. l.  On the basis of the amount of Yolk - Depending on the quantity of yolks, eggs can be  Alecithal / Microlecithal / oligolecithal - The amount of yolk pr
