In Australia, the platypus is officially classified as ‘Common but Vulnerable.’ As a species, it is not currently considered to be endangered. However, platypus populations are believed to have declined or disappeared in many catchments 1, particularly in urban and agricultural landscapes. In most cases, the specific underlying reasons for the reduction in numbers remain unknown. Platypus surveys have only been carried out in a few catchments in eastern Australia. It is, therefore, impossible to provide an accurate estimate of the total number of platypus remaining in the wild. Based on recent studies, the average platypus population density along relatively good quality streams in the foothills of Victoria’s Great Dividing Range is only around one to two animals per kilometer of the channel. Because platypus is predators near the top of the food chain and requires large amounts of food to survive (up to about 30% of a given animal’s body weight each day), it is believed that their numbers are most often limited by the availability of food, mainly in the form of bottom-dwelling aquatic invertebrates such as shrimps, worms, yabbies, pea-shell mussels, and immature and adult aquatic insects. Small frogs and fish eggs are also eaten occasionally, along with some terrestrial insects that fall into the water from overhanging vegetation. Catchments are an area of land drained by a creek or river system or a place set aside for collecting water that runs off the land’s surface. |

Platypus mostly eats food in the form of bottom-dwelling _______________. 5. The platypus needs to eat about 30% of the animal’s body weight each day to ___________. |

For the first question, it is mentioned in the first line of the passage that the platypus is not endangered, but it is officially classified as a common but vulnerable species. So, the answer is Vulnerable. For the second question, it is mentioned in the third line of the passage that the platypus population in the urban and agricultural landscapes has declined or disappeared in many catchments. So, the answer is urban and agricultural. Here, landscape means environment. For the third question, it is clearly mentioned in the passage that only one to two platypus per KM of the channel can be seen in the foothills of Victoria’s Great Dividing Range based on recent studies. So, the answer is One to Two. For the fourth question, it is given in the passage that the platypus mostly eats food which is mainly in the form of bottom-dwelling aquatic invertebrates such as shrimps, worms, yabbies, pea-shell mussels, etc. So, the answer is Aquatic Invertebrates. For the fifth question, it is mentioned in the tenth line of the passage that the platypus requires a large amount of food to survive up to about 30% of a given animal’s body weight each day. So, the answer is Survive. |
