BENGAL TIGER
The Bengal Tiger or Royal Bengal Tiger (Panthera tigris tigris or Panthera tigris bengalensis) is a subspecies of tiger primarily found in Bangladesh, India and also in Nepal, Bhutan, Myanmar and in southern Tibet. It is the second largest and the most common tiger subspecies, and lives in a variety of habitats, including grasslands, subtropical and tropical rainforests, scrub forests, wet and dry deciduous forests and mangroves. It is the national animal of India and Bangladesh.
PHYSICAL CHARACTERISTICS
Male Bengal Tigers measure 275–310 cm (sometimes up to 360 cm[citation needed]) with their tail. The tail of a large male is usually 85–95 cm long. Their weight ranges from 180 to 270 kilograms (400-594 pounds), with an average weight of 200–236 kg (440–520 lb). The heaviest Bengal Tiger ever reported was 389.5 kg and measured 320 cm between shoulders. Females are considerably smaller and have an average weight of 141 kg (310 lb), but they can reach up to 180 kg[3] (400 lb). Males have a maximum skull length of 330 to 380 mm, females 275 to 311 mm. The fur of this subspecies is generally orange-brown with black stripes, although there is a mutation that sometimes produces white tigers, as well as a rare variation (less than 100 known to exist, all in captivity) called the Golden Tabby as a white coat with golden patches and stripes that are much paler than normal.

2. PEAFOWL
The term peafowl can refer to the two species of bird in the genus Pavo of the pheasant family, Phasianidae. The African Congo Peafowl is placed in its own genus Afropavo and is not dealt with here. Peafowl are best known for the male's extravagant tail, which it displays as part of courtship. The male is called a peacock, the female a peahen, though it is common to hear the female also referred to as a "peacock" or "female peacock". The female peafowl is brown or toned grey and brown.
The Indian Peafowl is a resident breeder in the Indian subcontinent. The peacock is designated as the national bird of India.

1. NEEM
Neem  is a tree in the mahogany family Meliaceae. It is one of two species in the genus Azadirachta, and is native to Bangladesh, India and Myanmar, growing in tropical and semi-tropical regions. It is said, that it treats 40 different diseases.
Neem is a fast-growing tree that can reach a height of 15-20 m, rarely to 35-40 m. It is evergreen but under severe drought it may shed most or nearly all of its leaves. The branches are wide spread. The fairly dense crown is roundish or oval and may reach the diameter of 15-20 m in old, free-standing specimens.
The trunk is relatively short, straight and may reach a diameter of 1.2 m. The bark is hard, fissured or scaly, and whitish-grey to reddish-brown. The sapwood is greyish-white and the heartwood reddish when first exposed to the air becoming reddish-brown after exposure. The root system consists of a strong taproot and well developed lateral roots.The alternate, pinnate leaves are 20-40 cm long, with 20-31 medium to dark green leaflets about 3-8 cm long. The terminal leaflet is often missing. The petioles are short. Very young leaves are reddish to purplish in colour. The shape of mature leaflets is more or less asymmetric and their margins are dentate with the exception of the base of their basiscopal half, which is normally very strongly reduced and cuneate.
The flowers (white and fragrant) are arranged axillary, normally more-or-less drooping panicles which are up to 25 cm long. The inflorescences, which branch up to the third degree, bear 150-250 flowers. An individual flower is 5-6 mm long and 8-11 mm wide.

2. MANGO
The mango (plural mangoes or mangos) is a tropical fruit of the mango tree. Mangoes belong to the genus  Mangifera which consists of about 30 species of tropical fruiting trees in the flowering plant family Anacardiaceae. The exact origins of the mango are unknown, but most believe that it is native to Southern and Southeast Asia owing to the wide range of genetic diversity in the region and fossil records dating back 25 to 30 million years.
Mangoes retain a special significance in the culture of South Asia where they have been cultivated for millennia. It has been the national fruit of India, Bangladesh and Philippines. Reference to mangoes as the "food of the gods" can be found in the Hindu Vedas and the leaves are ritually used for floral decorations at Hindu marriages and religious ceremonies
                DESCRIPTION
Mango trees ( Mangifera indica ) are large, reaching 35-40 m in height, with a crown radius of 10 m. The leaves are evergreen, alternate, simple, 15-35 cm long and 6-16 cm broad; when the leaves are young they are orange-pink, rapidly changing to a dark glossy red, then dark green as they mature. The flowers are produced in terminal panicles 10-40 cm long; each flower is small and white with five petals 5-10 mm long, with a mild sweet odor suggestive of lily of the valley. After the flowers finish, the fruit takes from three to six months to ripen. The mango fruit is a drupe; when mature, it hangs from the tree on long stems. They are variable in size, from 10-25 cm long and 7-12 cm diameter, and may weigh up to 2.5 kg. The ripe fruit is variably colored yellow, orange and red, reddest on the side facing the sun and yellow where shaded; green usually indicates that the fruit is not yet ripe, but this depends on the cultivar. When ripe, the unpeeled fruit gives off a distinctive resinous slightly sweet smell. In the center of the fruit is a single flat, oblong seed (as big as a large stone) that can be fibrous or hairless on the surface, depending on cultivar. Inside the shell, which is 1-2 mm thick, is a paper-thin lining covering a single seed, 4-7 cm long, 3-4 cm wide, 1 cm thick.
