which is the correct order of the levels of organization from simple to complex?

• organism, population, community, ecosystem
• ecosystem, community, population, organism

Ostriches and gazelles eat together.  They both watch for predators and danger.  Since they see things differently, they each can identify threats the other animal may not see.  Both species are benefited.  

• mutualism
• commensalism
• predation
• parasitism

Mistletoe takes water and nutrients from the oak tree. This is good for the mistletoe but bad for the tree.

• mutualism
• commensalism
• parasitism
• competition

A bison walks through the grass, insects fly up and are seen and eaten by egrets.  This neither harms nor helps the bison, but it is easier for the egrets to get food.
