Article: Living in the wild can be hard. Finding food and staying safe aren't easy. Each day, animals struggle to survive in their habitats. Not all animals get by on their own. Some animals form a close partnership with other kinds of animals. These pairings are called symbiotic relationships. In a symbiotic relationship, the animals depend on each other. One animal helps the other meet its needs. Sounds good, right? Not always. Some animals are not very kind to their partners. In some cases, one animal meets its needs but hurts its partner. Take ticks, for example. These insects suck blood to live. To get blood, they attach themselves to other kinds of animals. Ticks can pass germs that cause disease instead of helping their hosts. In other relationships, animals don't treat their partners so poorly. Both animals benefit from living with the other animal. Small animals called cleaner shrimps have found a way of helping fish at coral reefs. As their name suggests, the shrimps clean the fish. They hang out at what scientists call a cleaning station. A fish stops by. Then a shrimp climbs onto the fish and even steps into the fish's mouth. The shrimp uses its tiny claws to pick stuff off the fish's body. That can include dead skin, tiny pieces of food, and wee creatures that can hurt the fish. The fish gets a nice cleaning. The shrimp enjoys a tasty meal of fish trash. Small birds called plovers are also in the cleaning business. They have big customers-crocodiles. Crocs have long snouts filled with sharp teeth. Cleaning them is tricky. When a croc opens its mouth, the plover hops right in. The croc does not snap its snout shut.Instead, it lets the plover eat small, harmful animals attached to the crocodile's teeth. The plover gets an easy meal while the croc gets clean teeth. Question: Why do the cleaner shrimps clean the fish? Yes or no, is the answer "To get fish trash for food."?
Yes

Q: Article: Children in the United States eat too much pizza that some researchers now argue the food should join the ranks of sugary drinks and fast food for the harm they do to health. In a new study, the researchers found that pizza is a large source of calories, saturated fat and salt in children's diets.Children should not eat more than two slices of pizza for a meal,and should pair that with salad, rather than with another high-calorie food,the researchers concluded. "Parents should aim to control pizza consumption , particularly as a snack where it was shown to have a very adverse impact on children, and they should put their pizza dollars toward healthier brands."Said Lisa Powel, director of the Illinois Prevention Research Center. Pizza has become a matter of focus in recent years for researchers who look at the meals children eat, rather than the nutrients within them.Studies have found pizza is among the greatest sources of calories for children. "Since pizza remains a common part of children's diet, we need to make 'healthy' pizza."Powel said.To make pizza healthier, food producers should reduce its saturated fat and salt, and increase its whole grain content," she said. Whether or not pizza is harmful enough to be picked out as an unhealthy food, the study attracts attention to a larger issue with the modern American lifestyle, said Alexis Tindall, who was not involved in the flow research. "Many foods are eaten too frequently and in large sizes," said Tindall.To solve the problem, people don't have to give up eating pizza, but instead, they can eat smaller and healthier pizza,"she said. "Make it at home, instead of ordering it out where you don't have any control over how it's made." Tindall said. "When we make it at home, we can choose healthier ingredients,increase the vegetables, reduce fat, and put in less cheese.Pizza doesn't have to be just pepperoni and cheese." Question: According to the research, children shouldn't eat _ . Yes or no, is the answer "more pizza with French fries"?
A: No
