!! 4.7.3, biodiversity Flashcards
list 5 programmes by governments and scientists
breeding programmes for endangered species
protection and regeneration of rare habitats
reintroduction of field margins and hedgerows in agricultural areas where farmers grow only one type of crop
reduction of deforestation and carbon dioxide emissions by some governments
recycling resources rather than dumping waste in landfill
why recycle waste
slow down expansion of landfill sites
reduces need to extract new natural resources
why are breeding programmes important
to prevent extinction events
2 consequences of global warming
change in distrubution
plants blooming earlier
what is stage 1 of the carbon cycle
Carbon is removed from the atmosphere by producers (e.g. algae)
who use it in photosynthesis
what is stage 2 of the carbon cycle
by consuming plant matter, animals obtain carbon compounds
what is stage 3 of the carbon cycle
carbon returned into the atmosphere (as carbon dioxide)
due to the respiration that happens in plant and animal cells
what is stage 4 of the carbon cycle
when animals and plants die decomposers return the carbon locked in their bodies back to the atmosphere via decay
what is stage 5 of the carbon cycle
combustion of fossil fuels is another source of carbon entry into the atmosphere
how is carbon removed form the atmosphere
via producers (e.g algae)
who use it in photosynthesis
how do animals contain carbon compounds
by consuming plant matter
how is carbon returned into the atmosphere as carbon dioxide
due to the respiration that happens in plant and animal cells
what happens when plants and animals die
decomposers return the carbon locked in their bodies back to the atmosphere via decay
name 3 sources of carbon entry into the atmosphere
decay
burning fossil fuels
respiration
stage 1 of the water cycle
water evaporates from the Earth’s surface, before rising up into the atmosphere
