A beach is a landform along the shoreline of an ocean, sea, lake orriver. It usually consists of loose particles which are often composedof rock, such as sand, gravel, shingle, pebbles or cobblestones. Theparticles comprising the beach are occasionally biological inorigin, such as mollusc shells or coralline algae.
The horse (Equus ferus caballus) is one oftwo extant subspecies of Equus ferus, or the wild horse. It is an odd-toed ungulate mammal belonging to the taxonomic family Equidae. Thehorse has evolved over the past 45 to 55 million years from a smallmulti-toed creature into the large, single-toed animal of today.
The tiger (Panthera tigris) is the largest catspecies, reaching a total body length of up to 3.3metres (11 ft) and weighing up to 306 kg(670 lb). It is the third largestland carnivore (behind only the Polar bear andthe Brown bear). Its most recognizable feature isa pattern of dark vertical stripes on reddish-orange fur with lighter underside
It has exceptionally stout teeth, and the canines are thelongest among living felids with a crown height of as much as74.5 mm (2.93 in) or even 90 mm (3.5 in). In zoos, tigershave lived for 20 to 26 years, which also seems to be theirlongevity in the wild. They are territorial andgenerally solitary but social animals, often requiring largecontiguous areas of habitat that support their preyrequirements. This, coupled with the fact that they areindigenous to some of the more densely populated places onEarth, has caused significant conflicts with humans.
A puppy is a juvenile dog. Some puppies may weigh 1–3 lb (0.45–1.4 kg), while largerones can weigh up to 15–23 lb (6.8–10 kg). All healthy puppies grow quickly after birth.A puppys coat color may change as the puppy grows older, as is commonly seen inbreeds such as the Yorkshire Terrier. In vernacular English, puppy refers specifically todogs while pup may often be used for other mammals such as seals, giraffes, guineapigs, or even rats.

The familyincludes tree squirrels, groundsquirrels,chipmunks, marmots (including woodchucks), flyingsquirrels, and prairie dogs.Squirrels are indigenous to theAmericas, Eurasia, andAfrica, and havebeen introduced to Australia.The earliest known squirrelsdate from the Eocene and aremost closely related tothe mountain beaver and to thedormouse among living species.
Green plants have cell walls with cellulose andcharacteristically obtain most of their energyfrom sunlight via photosynthesis using chlorophyllcontained in chloroplasts, which gives them their greencolor. Some plants are parasitic and may not producenormal amounts of chlorophyll or photosynthesize. Plantsare also characterized by sexualreproduction, modular and indeterminate growth, andan alteration of generations, although asexual reproductionis common, and some plants bloom only once while othersbear only one bloom.
A mushroom is the fleshy, spore-bearing fruiting body ofa fungus, typically produced aboveground on soil or onits food source. The standard forthe name "mushroom" is thecultivated white buttonmushroom, Agaricus bisporus;hence the word "mushroom" ismost often applied to those fungi(Basidiomycota,Agaricomycetes)that have a stem (stipe), a cap(pileus), and gills(lamellae, sing. lamella) or pores onthe underside of the cap.
Nature, in the broadest sense, is equivalent to the natural world, physicalworld, or material world. "Nature" refers to the phenomena of the physicalworld, and also to life in general. It ranges in scale from the subatomic tothe cosmic.
