Answer 9

water deficit

Question 10

what is the meaning of percolation

Answer 10

the downward flow of water through the soil into groundwater due to gravity

Question 11

river source, river mouth

Question 12

what are a few human activities that increase water pollution

Answer 12

not throwing away rubbish properly, factories releasing toxic chemicals into the sea

Question 13

what does water pollution do

Answer 13

it causes the water quality to fall, thus making the amount of clean water the decrease
it is also a threat to aquatic ecosystems; pesticides that kill plants and poison animals that eat them

Question 14

what is the process of desalination

Answer 14

filtration, reverse osmosis, conditioning, and disinfection

Question 15

what do forests help us with

Answer 15

generate oxygen, contribute to carbon storage, provide habitats for diverse animal types, provide protection from soil erosion and coastal erosion

Question 16

how do tropical rainforests contribute to carbon storage

Answer 16

carbon dioxide is absorbed through photosynthesis, the absorbed cd is stored in the plants’ leaves, branches, stems, and roots
dead leaves and branches fall to the ground and add carbon to the soil
the roots of the plant also produce soil carbon

Question 17

how do tropical rainforests prevent soil erosion

Answer 17

the leaves, branches, and stems of the plant slow down the falling raindrops before they hit the ground, thus letting more rainwater can infiltrate and percolate into the soil, reducing surface runoff
the roots of the plant will also bind the soil tgt

Question 18

Answer 18

bathing, cooking, flushing toilet

Question 19

how do people use water recreationally

Answer 19

canoeing, sailing, sport fishing

Question 26

what are the characteristics of the undergrowth

Answer 26

Answer 29

waxy leaves, broad leaves, drip tips, buttress roots

Question 30

what do 
waxy leaves, 
broad leaves, 
drip tips, 
buttress roots 
do, in order

Answer 30

reduces the amount of water vapour lost through transpiration,
larger surface area to absorb more sunlight,
allow rainwater to flow off easily,
help plants stay rooted to the ground

Question 31

characteristics of mangroves

Answer 31

low diversity, not many plant species have evolved to survive in water of high salinity, mangroves cannot survive in freezing conditions, no competition
