Marine Ecosystems and Food Webs

This week the Year 5 an 6 students have been learning about marine ecosystems and food webs.

An ecosystem is a group of organisms (plants and animals) living in a certain habitat that interact with each other.

A food web shows how plants and animals depend on each other for food and energy.

Students were given some notes made by a marine biologist about organisms in a rock pool and what they were eating.

The challenge was to use the evidence to develop a food web.

On the food webs the arrows show the direction that the energy is going. For example - when a crab eats some seaweed the energy is going from the seaweed to the crab.

It was hard work and everyone had to think about the evidence they were given. The students were thinking like scientists.

It was easier when students worked together on the task, sharing their knowledge.
