Organisms that live and derive food from other organisms are called parasitic organisms. The other organisms from which food is derived is called the host.

In symbiotic relations, usually, two different organisms live together and both benefit from the relation. An example is lichens, where fungal and algal partners live together for mutual benefit. Algal Component is autotrophic and produces food, while the fungal component provides shelter and water.

Some plants like pitcher plant (called insectivorous plants) are autotrophic, but to meet certain nutrient deficiency, i.e., mostly nitrogen deficiency, they feed on other organisms, usually insects. They are found in places where the soil nutrient value is less.

The living organism that lives in or on other organisms and derives nutrition from it is called a parasite. Parasites that are completely dependent on the host for nutrition are called total parasites. It is a type of heterotrophic nutrition. Amarbel (Cuscuta) are total parasitic organisms (plants) that have long, yellowish, tubular structure turning around stem and branches of trees.

Amit observed that the parasite amarbel was growing on the branches of bougainvillea plants on the boundary wall of his school. He also noted that the infected plants had smaller and yellowish leaves in comparison to the uninfected plants. He removed the long, yellowish, tubular structures of amarbel from some of the bougainvillea plants. He contacted the school gardener and showed him the parasite. He also informed the class teacher about it.
Answer the following question based on the above information:
What would have happened if Amit did not observe the parasite?
