• location
• niche

• Fundamental
• Realized

Match the following

• role of a species in an evironment

• habitat

• the niche that you can actually occupy

• Niche

• location where the organism lives

• Realized niche

• all that you are potentially able to do

• Competition

• when animals fight for to survival

• fundemental niche

Look at the picture, 5 warblers live in the same tree, but different areas and there is no competition between them.

Which statement is correct?

• They all have the same fundemental niche, but different realized niche

• They all have the same realized niche, but different fundemental niche
