<span>The ash trees are being cut when the show signs of
infestation of the ash borer. Ash borer in particular the Emerald Ash Borer
(EAB) is a tiny bug but can really do a great damage to the tree. When the tree
is infested with the ash borer, they lay their eggs in the bark of tree, when
the eggs hatch the lavas would start eating on the inner tissues of the tree
blocking the flow of nutrients and water in the tree that causes the tree’s to
death. If the tree is infested they cut
it down, burn and bury the wood to stop the spread of infestation. Ash trees
are valued for its strength and elasticity that is often used to make baseball
bats, bows, tool handles and other products that needs durable wood.</span>

Mycorrhizae are associations between fungi and the roots of plants, where the Fungi provides minerals to the plant. It enabled plants and fungi to be the first organisms to invade land successfully 430 million years ago. In most cases the relationship between host plants and the mycorrhizal fungus is mutualistic, or mutually beneficial. The Mycorrhizal fungi come into direct contact with plant roots and with the soil, adding to the plants ability to gather nutrients and water from the soil through the fungus.
Answer:
Homeostasis is defined as the state of body in which body maintains several chemical and physical changes inside the body affected by external factors.
Negative feedback loop includes a sensor, stimulus, control center, and effector which is used to control homeostasis.
A negative feedback loop is a reaction that reduce an excessive response and maintain the functions within the normal range. for example: if temperature and blood glucose level increases in the body, negative feedback loops control both the variables and maintain homeostasis.
Hence, negative feedback loops used to control body homeostasis.
