Kindergarten kids make presentations on ecosystem and food chain
Armed with knowledge of amphibians and insects, kindergarten students at Balestier campus made a presentation on the pivotal role of these organisms in the overall ecosystem.
Students of K2A explained the physical features of amphibians and their importance in the food chain. Students of K2B also talked about insects like butterflies, ladybugs, dragonflies etc, small living creatures in nature that are equally important in the food chain as well as provide beauty to the environment.
At the presentation, students explained how every species, whether they are endangered or not, need to be protected with the overall aim of harnessing life on Earth. For example, how frogs (and toads) are beneficial to humans as they feed on insects that could harm crops. They are also important source of food for birds, snakes and others in the food chain.
Children also explained that amphibians like salamandar, pollywog, caecilians make good indicator species because they live in two environments, land and water, and have thin skin that they sometimes breathe through. Our thin skin can also absorb toxic chemicals, radiation, and diseases. If there are lots of frogs and other amphibians in a habitat, it means the ecosystem is healthy.
Students of K2B explained that insects like ladybugs help the environment by feeding on harmful tree-dwelling insects like aphids, dragonflies etc. Bees and butterflies play a vital role in the pollination of plants and the production of crops. Students also explained how cockroaches and mosquitoes are carriers of diseases, and how to carry out Mozzie wipe out that will help stop breeding of mosquitoes and subsequently stop spreading of deadly diseases like dengue, malaria and yellow fever.
