Carnivores are flesh-eater. Omnivores eat plants as well as flesh. And detritivores feed on dead plants and animals. And detritivores are of two types: o Scavengers o Decomposers Scavenger ingests dead material and then digests. Decomposers digest dead material and then ingest it. Scavengers do not break down organic compounds in the dead remains into simpler molecules. But decomposers decompose the complex molecules in dead remains into simpler compounds and that is again returned to the soil. Now let's learn about Heterotrophy or Heterotrophic mode of nutrition There are three types of Heterotrophic modes of nutrition. • Holozoic nutrition • Saprophytic nutrition • Parasitic nutrition Let's first learn about Holozoic nutrition This type of nutrition is heterotrophic nutrition in which food is ingested and then internal processing of gaseous, liquid, or solid food particles is done. Now let's learn about the second type of heterotrophic nutrition which is saprotrophic nutrition. Saprotrophs or decomposers The taking of nutrition from dead organic matter in the form of solution is called saprotrophic nutrition. And the organisms which use the saprotrophic mode of nutrition are called saprotrophs. For example fungi. Let's learn more about the saprotrophic mode of nutrition. Saprotrophs are non-green plants. Examples: mushrooms, yeast, and bacteria. Saprotrophs get their food from dead or decaying organic matter, they grow on dead organic matter such as cow dung, wood, bread, etc. They secrete the digestive juices on dead organic matter and dead organic matter is digested outside their body and then they absorb the digested food material in the form of juices from that organic matter. This is called the saprotrophic mode of nutrition. Now let's learn about other heterotrophic modes of nutrition which is Parasitic nutrition. It is a type of heterotrophic nutrition in which an organism which is called a parasite lives on the body surface or inside the body of another type of organism which is called a host. The parasite gets nutrition directly from the body of the host. This mode of nutrition is called parasitism and it's the relationship between two organisms. Where one is called a host and one is called a parasite and the parasite drives at the cost of the other which is called the host. So a parasite derives its nutrition from the host organism which is most harmful to the host organism as the host has to feed the parasite from its share of nutrition. And the relationship between the host and the parasite is called a symbiotic relationship. Parasites can be of two types: • Endoparasites • Ectoparasites I hope you liked our video. Kids should spend time watching informative videos and expand their knowledge day by day. Kids retain what they see in audio-visual lessons so make them watch informative videos rather than cramming things.
