Question 10

2. The fungus known as "chicken of the woods" grows on trees. The fungus breaks down the tree and gets its nutrients that way. The tree decays, gets weak, and becomes very vulnerable to extreme weather. 3. Tapeworms are a particular species of worm that resides in the small intestine of mammals (including humans). The tapeworm latches on to the walls of the small intestine, and siphons (steals) nutrients from the mammal's digestive tract. This can cause severe nutrient deficiency, weakness, and extreme weight-loss for the mammal. 4. Cattle Egrets are a type of bird commonly found on farms. As cattle, horses, and other livestock graze (eat grass) on the field, they cause movements that stir up various insects. As the insects are stirred up, the cattle egrets following the livestock catch and feed upon them. 5. Oxpeckers are a small bird commonly found on rhinoceroses. The oxpecker feeds on the parasites that cover the rhinoceroses' skin. The bird gets a meal and the rhinoceros is relieved of the harmful parasit
