Y4 - Pulau Ubin: Habitats, Ecosystems & Food Chains


Habitats and Ecosystems in Pulau Ubin

You can find many habitats for the wildlife in Pulau Ubin, such as beaches, mangroves and wetlands and coral rubble. A habitat is the area where a plant or animal naturally lives and grows. In every habitat there is an ecosystem, where a large community of living organisms (plants, animals and microbes), depend on each other to survive. Disruptions to an ecosystem can be disastrous to all organisms within the ecosystem.

The Chek Jawa Wetlands located at the eastern end of Pulau Ubin is a unique natural area where six major habitats and ecosystems – sandy beach, rocky beach, seagrass lagoon, coral rubble, mangroves and coastal forest - meet and mix!

Food chains in ecosystems

Food chain picture example

A food chain describes how different organisms eat each other, starting out with a plant and ending with an animal. For example, you could write the food chain for a lion like this: 

grass ---> zebra ---> lion

The lion eats the zebra, which eats the grass. 

Plants get their energy from the Sun. They are called producers because they make their own food. Animals are called consumers because they eat plants and other animals. They do not make their own food. Animals that eat other animals are called predators. The animals they eat are called prey.
