Effect Flashcards
8 effects
- Ice melting
- Thawing of permafrost
- Reducing fresh water supply
- Increase sea levels
- Disruptive weather patterns
- Disrupt natural eco system
- Coral reefs death
- Migration
Ice melting leads to?
- thawing of permafrost
- reducing fresh water supply
- increase sea level
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
disruptive weather pattern is?
Unusually wet and dry;
Water and temp
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
How does water affects?
@plant
- Dehydration
- Photolysis of water
- PSII at thylakoid membrane
Dry weather affects?
-heatwaves= consecutive hot days
- evaporation
- > pption
-energy not utilised are released as heat
Disrupt natural ecosystems reduces?
Biodiversity
- no of species;
- genetic variability;
- habitat;
Consequence of reduction in biodiversity
Food source;
Bio medicine
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
Coral anatomy
Animal with digestive systems;
Zooxanthellae
-contains photosynthetic pigments to px glucose
Coral at shallow water
Most sensitive to climate change;
Expel zooxanthellae in stress envir;
Losing Colour
How is coral affected in acidic ph
CaCO3 skeleton
pH starts to decrease;
Dissolve CaCO3;
Lost of habitat
3 forms of migration
- Away (fish)
- To (mosquitoes)
- Stay (insect)
