Our Biology study

Members: Scarlett, Vaani and Mahnoor 

In science we have been learning about food chains and food webs. We thought that it would be great to teach this concept to the 5 to 6’s. One of the things we talked about was the food chain.  


The term food chains means a series of organisms each dependent on the next as a source of food. The food chain depends on a delicate balance of nature. When one organism is removed that delicate balance can be affected in a number of ways.

The prey/predator relationships change. Interrelationships within a food chain can be so intricate that a chain of disruptive events can occur when one ecosystem component changes. Therefore, When a predatory species becomes threatened this removes a check and balance in the food chain on the population of prey previously consumed by that predator. Endangerment or extinction of one species can threaten the viability of another species. If one species in the food web ceases to exist, one or more members in the rest of the chain could cease to exist too. A plant or animal doesn’t even have to become extinct to affect one of its predators. 

The game

A five minute presentation was giving using this information. We wanted the children to get involved as well. We desiged a fun game on scratch and did a physical demonstration to inform them about this whole fun topic. 

The game was about a blue tang fish and reef shark. The aim of the game is to eat as many fish as they can. The concept is to show that if the clownfish goes extinct, the reef shark will not have any food. therefore, the population will go down. This game showed that no matter how little or big the animal is that they are all very important, because if the animals die we will die too because animals are one of the sources of food.
