3. Fungi

Fungi is a group of simple plants that have no chlorophyll .There are some species of fungi that are single celled organisms, and there are other kinds of fungi that are multi-cellular organisms. Fungi are made up of filaments called hyphe that are stacked together from end to end.   

Some kinds of fungi live on land and other types of fungi live in water environments. Since fungi has no chlorophyll, it can not make its own food. Some types of fungi lives off of other organisms and are parasites, but other fungi species feed off of dead and decaying matter. A third kind of fungi lives with other organisms and neither the fungi or the organism is hurt. This kind of relationship is called positive symbiosis .

Fungi can be found on mouldy bread, rotten food, trees and forest floors. For examples ...
