What type of interaction have you found?

If you watched the  Evolutionary Arms Race, one of the stories was about leaf cutter ants.  To refresh your memory (or tell you for the first time), leaf cutter ants harvest leaves, but do NOT eat the leaves.  Instead they shred the leaves and "feed" them to a special type of fungus that they tend inside a "garden" in their nests.  The "garden fungus" is very special and is only found in these ant gardens--it is dependent upon the ants to care for it, and the ants eat a part of the fungus in return.  Answer the following questions: What kind of relationship exists between the leaf cutter ants and the "garden fungus"?  mutualism If a type of "weedy" mold starts to grow on the leaves in the fungus garden, the ants will remove it.  This reduces [選擇] herbivory competition between the "garden fungus" and the weed mold.

It is extremely flexible when wet, and is adapted to create interesting shapes. Many urban public buildings, such as universities, have also used concrete as the main material to indicate strength and permanence. Instead of keeping Brutalist buildings, many are being demolished to make space for modern styles. However, this does not acknowledge the cultural history of these buildings, and is not sustainable. Fill in the gap with ONE WORD from the paragraph. 1. Brutalist architecture included exposed concrete, which gave a cold Answer Question 1[input] .
