carbon and water cycle

Question 1

water cycle

Answer 1

- water falls back to earth as liquid (precipitation)
- water may seep into soil, flow into rivers, be taken up by plants etc.

Question 2

carbon stores

Answer 2

air as CO2
plans + animals ( locked up in biological molecules)
soil (contains bacteria and other microorganisms)
fossil fuels underground

Question 3

how carbon moves between stores

Answer 3

photosynthesis - plants take in CO2 from atmos and convert it to molecules like glucose
carbon then: passed out to atmos by respiration
- or passed on to animals that eat the plants, animals then respire releasing CO2
