Eco-column as an ecosystem

Definition of an eco-column

A biological community of interacting organisms and their physical environment.

                     

There are 3 things that show that our eco column is an ecosystem.

·        The abioitc factors

·        The biotic factors

·        The food chains in the eco column

Abiotic

We have abiotic factors such as soil, water and light. These are all resources that our plants and insects can use to survive.

Soil                                                                                                          Water

 

Our plants use the water and nutrients in the rich soil to grow. The water plants live in the water and so they have no problem growing.

Biotic

Our biotic factors include wheat grass, a fern, pond weed, snails, fruit flies, tiny water snails, aphids and a small spider.

This shows that our eco-column is definitely an ecosystem as we have biotic factors which share the resources in the column between them and they interact with each other by eating one another. These biotic factors also interact with the abiotic factors to survive.
