8 effects

1. Ice melting
2. Thawing of permafrost
3. Reducing fresh water supply
4. Increase sea levels
5. Disruptive weather patterns
6. Disrupt natural eco system
7. Coral reefs death
8. Migration

2

Ice melting leads to?

-thawing of permafrost
-reducing fresh water supply
-increase sea level

3

Explain thawing of permafrost

Biomass accumulated as the frozen permafrost is not available to decomposers;

Glacier top melts, expose biomass to degradation;

Convert carbon sink to CO2 source

4

disruptive weather pattern is?

Unusually wet and dry;

Water and temp

5

At increasing high temp?

-associates with smaller dice animal and reduction of mass;

-increase metabolic pathway way
->KE in enzymes

-substrates becomes limiting factors
-> in order to compensate, size of mass decreases

=> reduces food supply; decreasing yield

6

How does water affects?

@plant

1. Dehydration

2. Photolysis of water
-PSII at thylakoid membrane

7

Dry weather affects?

-heatwaves= consecutive hot days

-evaporation
-> pption

-energy not utilised are released as heat

8

Disrupt natural ecosystems reduces?

Biodiversity

-no of species;
-genetic variability;
-habitat;

9

Consequence of reduction in biodiversity

Food source;

Bio medicine

10

Problem of artificial selection

traits pure breeding;

Parent plants are homozygous;

=> diseases come, all the same organisms will be destroyed as there is no allelic diversity

11

Coral anatomy

Animal with digestive systems;

Zooxanthellae
-contains photosynthetic pigments to px glucose

12

Coral at shallow water

Most sensitive to climate change;

Expel zooxanthellae in stress envir;

Losing Colour

13

How is coral affected in acidic ph

CaCO3 skeleton

pH starts to decrease;

Dissolve CaCO3;

Lost of habitat

14

3 forms of migration

1. Away (fish)

2. To (mosquitoes)

3. Stay (insect)
