ECOLOGY - Recycling Materials

Question 1

Carbon Cycle

Answer 1

Photosynthesis in which green plants and algae take in CO2 from atomasphere to convert it into glucose. Then can go into atomasphere by respiration or passed onto animals that eat plants. Animals can respire to release CO2. When animals/plants decay they release CO2. Fossil fuels then burned by humans to release CO2 into atomasphere

Question 2

Water Cycle

Answer 2

Energy from the sun causes some of water to evaporate. Also evaportation of water from leaves is called transpiration. As all water vapour accumulates in the sky it starts to condense into clouds and at some point water then falls back down into earth as liquid water in the form of rain which is called percipitation
