biodiversity

Question 1

describe the biomes
boreal forset
tropical rainforest
tropical grassland

Answer 1

tropical rainforst: hot all year wet all year
boreal forst: warm summers cold winters
tropicdal grassland: hot all year rainy season and dry season

Question 2

temperate forst
temperate grassland
tundra

Answer 2

temperate forest warm summers cool winters

temperate

Question 3

explaining ecosystems due to latitude

Answer 3

Because of the earths curvature, the suns rays hit the earth at different angles. The suns rays hit the equator at a right angle. This means that the rays are more concentrated, however at the poles the suns rays hit the earth at a higher degree of angle meaning that the rays are less concentrated and weaker. This means that the vegetation doesn’t Photosynthesise as much making it harder for vegetation to grow shaping the biome in how it looks and the species that are there.

Question 4

what is the biosphere

Answer 4

the biosphere includes all life living on earth including life living in the hydrosphere and the geosphere.

Question 5

revise nutrient cycle in the book

Question 5

revise nutrient cycle in the book

Question 6

what are the inputs and outputs of the nutrrient cycle

Answer 6

rainfall weathering

outputs surface run off

Question 7

what are the transfers in the nurtient cycle

Answer 7

leaf fall
decomposition
uptake by plants

Question 8

woodland characterisitcs and plants

Answer 8

mostly trees

england has mostly deciduous trees scotland and wales have non native

Question 9

moorland

Answer 9

rough grassland and peat bogs

heather dominates also rare birds

Question 10

wetland

Answer 10

low nutrinet waterlogged soil
wading birds
bog mosses

Question 11

benefits to the uk via the c9oastal ecosystem

Answer 11

tourism
fishing
energy via wind

Question 12

explain each layer of rainforest trees

Answer 12

emergent trees tallest parts of trees
main canopy main cluster of trees
understory 3% of light reaches here
shrub layer
forest floor

Question 13

adaptations of plants in the rainforest

Answer 13

drip tip leaves so water doesn’t stay on it and then cause it to run off
trees have buttres structures therefore entailing that they then have shallow large surface area.
lemur has gripping hands and feet so it can leap from tree to tree.

Question 14

explain nutrient cycle in the rainforest

Answer 14

large biomass store
small soil store due to large uptake
rapid decay due to large amounts of heat so ideal temp for bacteria
continual supply of litter
small litter store due to rapid decomposityion

Question 15

how will climate change effect the rainforest

Answer 15

longer dry periods will mean more CO2 being emitted.

change in climatic conditions will mean there may be a lower chance of survival for plants

Question 16

essay on costa rice ecotourism

Answer 16

generates large income for local people and doesn’t harm natural environment and makes more money than traditional practices
dont have to chop down the forest
education for tourists

Question 17

selective logging

Answer 17

involves the cutting down of trees at a certain height, the overall structure of the forest is maintained
local people can get jobs
forests structure is still maintained

Question 18

agroforesty

Answer 18

growing rainforest trees and commercial products at the same time, prevents soil erosion 
crops benefit
no damage donw
provides local work
highly profitable.

Question 19

how does the soil in the DW differ from the soil in the rainforest

Answer 19

in the rainforest the soil has less nutrients due to a high uptake from plants to the higher biomass levels.

Question 20

adaptations of oak trees

Answer 20

large strong branches that spread horizontally to capture as much light as possible
large deep roots to access many minerals and to anchor tree in windy conditions
in automn supply of water is cut from the leaves by a seal so that it falls of and dies

Question 21

plants and animals in the DW

Answer 21

horizontal branches so that can get the most sunlight possible
foxes have large ears therefore this allows them to hear prey, also fur coat keeps them warm.

Question 22

describe nutrient cycle

Answer 22

large litter layer
large soil store
slwo rate of decompostion
leaching often happens due to high rainfall. 
stores are of similar size
large rainfall in winter months

Question 23

dw goods and services

Answer 23

goods 
timber
fuel
services
recreation
carbon capture
conservation

Question 24

climate change significance to ecosystem

Answer 24

increased risk of drought: Trees in DW are not adapted to drought
increased risk of fire
mild winters meaning non native trees outcompete native

Question 25

causes of deforestation

Answer 25

social
veichles increased so land has to be cleared fro the motorway
clearing land for farming
economic
selling timber
coiferous trees produce softwood

Question 26

issues facing the new forest

Answer 26

visitor damage

timber is extracted from softwood and hardwood, some operations are not compatible with visitors

Question 27

managing the new forest

Answer 27

control of visitors: car parks bike lanes

visitor leaflets: explaining conservation to them

Question 28
