11. Just before you reach the top of mountain where there is year round ice and snow , you would expect to see
ans.(d) herbs , lichens and mosses
12. in a tropical rain forect you would expect to find
ans. (c) small trees, shrub and grasses
13. which of the following statement is true
ans. tropical rain forest occur 10 degrees of north and 10 degrees of sounth from the equator. so the right option is (C) tropical rain forest are located near the equator where it is warm and wet.
14. which of the following is true of tropical rain forest?
ans. tropical rainforest contain high biodiversity . it include 42 ,000 species of insect , 313 species of tree and 1500 species of larger tress has been fpund here. because soil is fertile here
and temperature is not vary widely and grassland not only exceedingly.
so the option (a) is true.
15. the amount of light available to each layer of a tropical rain forest from least to most light is
ans. light is important factor in the growth of the plant or tree because with the help of light they are able to do photosynthesis process and make their food . more light availibility lead to more growth so the layer of the tress are according to the light availability from least to most is
(c) under story, lower canopy, upper canopy , emergent layer
16.which of the following is not characterstic of salt marshes and mangrove swamps?
ans. salt marsh and mangrove swamps both provided habitat for wildlife, in sundarvan mangrove 40,000 royal bengal tiger has been occurred and bothe are thretened by the development because pollution which is generated from unbalanced and unorganized development affected coastal areas very badly and increasing earth temperature which is affecting it very badly. and both are found along coastal areas.
salt marsh and mangroove are dominated by salt tolerant plants where marsh grasses are found along stream and or along the fresh water, so this ststement is not chracterstic of the salt marsh and mangroove.
