Q.1 Under IUCN Manatee has been classified under which category ?
A) Endangered
B) Vulberable
C) Extinct
D) Critically endangered
Ans. A
They are large, fully aquatic, mostly herbivorous marine mammals sometimes known as sea cows All three species of manatee are listed by the World Conservation Union as vulnerable to extinction. It is illegal under federal and Florida law to injure or harm a manatee. They are classified as “endangered” by both the state and the federal governments. Manatees inhabit the shallow, marshy coastal areas and rivers of the Caribbean Sea and the Gulf of Mexico (T. manatus, West Indian manatee), the Amazon basin (T. inunguis, Amazonian manatee), and West Africa (T. senegalensis, West African manatee). West Indian manatees prefer warmer temperatures and are known to congregate in shallow waters. They frequently migrate through brackish water estuaries to freshwater springs. They cannot survive below 15 °C (60 °F). Their natural source for warmth during winter is warm, spring-fed rivers.

Q.4 Which among the following is/are correct with respect to the Sambhar lake ?
1. It is an elliptically shaped lake surrounded on all sides by the Himalayas
2. It is not part of the Ganga river basin area
Select the correct answer using the codes given below :
A) Only 1
B) Only 2
C) Both are correct
D) Both are incorrect
Ans. B
The lake receives water from an endorheic basin with 5700 square km catchment area.
It is not part of the Ganga river basin area and is geographically a separate land locked river basin.
The lake is actually an extensive saline wetland, with water depths fluctuating from as few as 60 centimetres (24 in) during the dry season to about 3 meters (10 ft) after the monsoon season.
It occupies an area of 190 to 230 square kilometers, based on the season.
It is an elliptically shaped lake 35.5 km long with a breadth varying between 3 km and 11 km.
It is located in Nagaur and Jaipur districts and it also borders the Ajmer district.
The circumference of the lake is 96 km, surrounded on all sides by the Aravali hills.
The Sambhar lake basin is divided by a 5.1 km long dam made of sandstone.
It is India’s largest saline lake and is the source of most of Rajasthan’s salt production.
Sambhar has been designated as a Ramsar site (recognized wetland of international importance) because the wetland is a key wintering area for tens of thousands of flamingos and other birds that migrate from northern Asia.
The specialized algae and bacteria growing in the lake provide striking water colours and support the lake ecology that, in turn, sustains the migrating waterfowl. There is other wildlife in the nearby forests, where Nilgai move freely along with deer and foxes. The salt (NaCl) concentration in this lake water differs with season.
The salt concentration in the pans Kyars varies and accordingly the color ranges from green, orange, pink, purple pink, red due to the bloom of haloalkaliphilic microorganisms.

2. Mangroves
3. Ferns
Select the correct answer using the codes given below :
A) 1 & 3
B) Only 2
C) 1,2,3
D) 2 & 3
Ans. C
Wetlands occur naturally on every continent except Antarctica,the largest including the Amazon River basin, the West Siberian Plain,and the Pantanal in South America. The water found in wetlands can be freshwater, brackish, or saltwater. The main wetland types include swamps, marshes, bogs, and ferns; and sub-types include mangrove, carr, pocosin, and varzea. The UN Millennium Ecosystem Assessment determined that environmental degradation is more prominent within wetland systems than any other ecosystem on Earth Wetlands have also been described as ecotones, providing a transition between dry land and water bodies. The most important factor producing wetlands is flooding. The duration of flooding determines whether the resulting wetland has aquatic, marsh or swamp vegetation. Other important factors include fertility, natural disturbance, competition, herbivory, burial and salinity.When peat accumulates, bogs and ferns arise.
