tropical rainforests

Question 1

name 2 plant adaptations

Answer 1

buttress roots and drip tip leaves

Question 2

name 3 animal adaptations

Answer 2

poisson dart drog, squirrel monkey, glass frog.

Question 3

name some plant adaptations in a deciduous woodland

Answer 3

bluebells flower early, leaves are broader, branches spread out horizontally

Question 4

name some animal adaptations in a deciduous woodland

Answer 4

aninals hibernate in the winter and lower metabolism to conserve energy and not look for food, since its harder in winter, they migrate during cold seasons, squireels bury food to survive winter

Question 5

give a few services of a tropical rainforest

Answer 5

carbon capture (2 billion tonnes), tourism, maintains biodiversity -> optimum conditions which allows a range of organisms to live there

Question 6

give a few goods of a tropical rainforest

Answer 6

drugs (rosy periwinkle- treats childhood leukaemia), food for indigenous people, oxygen and timber

Question 7

give a few services of a deciduous woodland

Answer 7

recreation (cycling, nature walks) and conservation -> helps preserve rare plants and animal species by replanting trees, protecting habitats.

Question 8

give a few goods of a deciduous woodland

Answer 8

timber (13 million tonnes) 2014, fuel- biomass is burnt e.g air-dried wood for burning stoves

Question 9

what is the case study for tropical rainforests and deciduous woodlands

Answer 9

madagascar (trf) and new forest woodland (dw)

Question 10

explain tavy / slash and burn

Answer 10

trees are cut down, then burnt. when they are burnt, they leave behind ash containing nutrients. this nutrients Is left to be added to the soil, making it more fertile, acting as a natural fertiliser which helps crops grow. but, these nutrients/minerals/ions are easily washed away due to the rainfall in a tropical rainforest. therefore, the whole process must be done again

Question 11

why was logging done in Madagascar? and give some reasons for illegal logging

Answer 11

it was don so Madagascan government could sell timber for money to pay offf international debts. then, illegal -> corruption (police allowed it for money) , magascan people are poor, high demand for rosewood (fragrant)

Question 12

why is there deforestation in trfs?

Answer 12

tavy, increased population and logging (illegal/legal)

Question 13

why is there deforestation in dw?

Answer 13

widen carriageways (congestion), ups population increased from 52.4 million to 64.1 million-> houses,

Question 14

how is the new forest woodland being managed sustainably? (what are they doing to manage is sustainably)

Answer 14

pesticide and herbicide use is limited, when coniferous trees are chopped down, they are replaced by native deciduous trees, forestry is controlled by the forestry commission

Question 15

how is the new forest being used sustanably? - how is it being used sensibly?

Answer 15

paths have been made which direct visitors away from vulnerable areas, protecting the wildlife- stops footpath erosion, leaflets have been made ‘5 ways to love the forest’ -> educates visitor on why to drive slowly, government schemes - grants can be given to local landowners by using techniques such as coppicing to manage tree growth & plant native species

Question 16

what is coppicing?

Answer 16

cutting trees just at ground level or above the root so they can still grow easily

Question 17

how is Madagascar being managed sustainably?

Answer 17

farmers have agreed to set aside an area where young trees can grow without being cut- more trees and they help improve the soil. schools have been set up, educating children on why they should care for the turf. ecotourism -> locals have created a group of guides to take tourists around the reserve, this money also pays them to look out for illegal logging, preventing more deforestation
