Carpenter ants get their name because they build their nests in wood. This pest can cause significant damage to your house. There are many types of carpenter ants. measuring in size from one-quarter inch (about the width of a pencil) for a worker carpenter ant to three-quarters of an inch (about the size of a quarter) for a queen carpenter ant.
Each colony is established by a single, fertilized queen. She starts her nest in a cavity in wood, where she raises her first brood of workers. She feeds them saliva and does not leave the nest or feed herself during this time.
When they are ready, those workers then get the job of gathering food to feed the next generation. Once mature, this first generation of worker ants work to increase the food supply for the colony. The colony population grows very rapidly. A colony can eventually produce 2,000 or more workers.
Carpenter ants do not eat the wood they remove during their nest-building activities, but deposit it outside entrances to the colony in small piles. The diet of carpenter ants includes living and dead insects, meat, fats and sugary foods of all kinds, including honeydew and nectar from plants.
Carpenter ants build nests anywhere they can find water and moldy or damp wood, such as tree stumps, firewood or in the plants around your house. Carpenter ants also build nests inside, usually entering buildings through wet, damaged wood, although it isn’t uncommon for them to adapt to drier environments.
Carpenter ants don’t carry disease, but when building a nest inside a home, Carpenter ants dig smooth tunnels inside the wood. These tunnels weaken the wood and potentially damage the wood that keeps the house standing. This kind of damage can be very expensive to fix.
Contoh Report Text Tentang Ikan Hiu Putih the great white shark
Few creatures strike more fear in humans than the great white shark. In reality, great white shark attacks on humans are rare – and it is even rarer for one of these attacks to be fatal. However, the size of the great white shark and its efficiency as a predator add to the perpetuation of this unnecessary fear.
The great white shark averages 4.5 m (15 ft.) in length, but some have been recorded as large as 6 m (20 ft.) long! They generally weigh up to 2250 kg (5000 lb.).
Great white sharks are blue-gray on the dorsal, or top, part of their bodies. This helps them blend in with the bottom of the ocean when viewed from above. The belly, or ventral, part of the body, is white. This makes it difficult to see the sharks from below, with sunlight shining in around them. They have strong, torpedo-shaped bodies and powerful tails that help them swim. Great whites can reach speeds up to 24 km/hr (15 mph).
Great whites use their speed and coloring to help them hunt. They search for prey at the surface of the ocean while swimming below. Once they spot a target, they use a burst of speed to bump their prey while simultaneously biting it. They have several rows of teeth that can number into the thousands. As teeth fall out, they are rapidly replaced by those in the row behind them. These sharp, serrated teeth can be devastating. A single, large bite can be fatal.
When great white sharks are young, they feed on smaller prey, like fish and rays. As they grow larger, they feed more exclusively on marine mammals, such as sea lions, seals and small whales.
The great white is at the top of the food chain and has few threats in the ocean. Only orcas and larger sharks can pose a risk. The only other risk to the great white shark is human interaction. They are sometimes caught by accident in fishing nets or intentionally sought out by sport fisherman. Their jaws and fins are sold for considerable amounts of money.
Not much is known about the mating habits of great white sharks. What is known is that after mating the female develops several eggs which hatch in her womb. The newly-hatched shark pups feed on unfertilized eggs in the womb as they develop before being born. In general, the mother gives birth to a litter of two to ten pups, each of which average 1.5 m (5 ft.) in length. Male great whites reach maturity at 9-10 years of age. Females mature even later, between 14 and 16 years of age. Female sharks are thought to give birth once every couple years, but even that is uncertain.
Great whites spend their time in temperate waters all over the world, although they have been known to make brief trips into colder water in the north. They live in the upper part of the ocean, towards the surface, and close to the shore, where sunlight shines through and prey is available.
Polar bearPolar bears, or “sea bears,” are the world’s largest land predators, weighing up to 600 kg (1300 lb.) and measuring up to 3 m (10 ft.) tall. On average they live to be about 25 years old, reaching sexual maturity at around 4 years.
Although they appear white or yellow in color, their fur is actually clear and hollow, and their skin is black. Their visibly pale coloring is caused by the reflection and scattering of light.
Inhabiting the ice and sea of the Arctic, polar bears are well-equipped for survival in a harsh environment. Two coats of fur and a thick layer of blubber help insulate the polar bear’s body from the cold, keeping its temperature at an even 37° C (98.6° F). In addition, polar bears’ paws are especially adapted for walking on the ice and swimming in the sea. Hairs and bumps on the soles of their feet provide traction, while webbing between their toes allows for effective swimming strokes.
Polar bears are also equipped with strong noses. They use their powerful sense of smell when hunting for seals, their main source of food. They can smell a seal’s breathing hole, or aglu, up to one mile away. Once located, a polar bear will wait patiently by the hole and attack the seal’s head when it comes up for air. In ideal hunting conditions, the bear will just eat the seal fat, leaving the carcass for other animals. However, when food is scarce, polar bears will eat just about anything. Supplemental foods include walruses, short-legged reindeer, birds, bird eggs, kelp, and beached whales. When in proximity to human settlements, they have even been known to eat garbage such as Styrofoam.
Polar bear cubsPolar bears do not hibernate like other bears, but females do enter into a dormant state while pregnant. After mating in the spring, a female polar bear spends the summer ingesting large amounts of food and building a maternity den in a snow drift to prepare for the arrival of her cubs.
In the fall, she enters into a dormant state, remaining this way even as she gives birth. The litter, usually two cubs, will spend two years with their mother learning essential hunting and survival skills.
Contoh Report Text Tentang Zebra Plains Zebra
Black and white stripes make the zebra one of the most recognizable animals in the world. The plains zebra, also known as the common zebra, is the most abundant of three species of zebra, inhabiting the grasslands of eastern and southern Africa. The other two species are Grevy’s zebras and mountain zebras.
On average, plains zebras are smaller than the other two species of zebra. They range in height from 1-1.5 m (3.5-5 ft.) and can weigh almost 450 kg (1000 lbs.). Plains zebras also have a different stripe pattern than the other species. They have broad stripes that run horizontally towards the back and vertically towards the front, meeting in a triangle in the middle of their bodies. They also have a stripe that runs down the center of their backs onto the tail. Finally, plains zebras have underbelly stripes. Although all plains zebras share these similarities in stripe patterns, no two zebras have exactly the same pattern.
Zebras have very good hearing and eyesight, which helps them stay clear of predators such as lions, hyenas, and cheetahs. It also helps that they can run 56 km/h (35 mph) and pack a powerful kick. If one zebra spots a predator, it lets out a sharp two-syllable call. The young and female zebras run, while the males trail behind to defend them. If one is attacked, others circle around to help protect it from predators.
Plains zebras are herbivores, meaning they eat plants. They spend the majority of their day eating, mostly grazing on grass, but also eating leaves and stems. To keep up with the frequent grinding of these foods, zebras’ back teeth continue to grow throughout their lives.
Zebras are known to travel great distances to find food and water when the dry season arrives.
