ecosystem services

• pollination for food
• seed dispersal for spreading plant life eg elephants eating fruit and distributing seeds in faeces
• atmosphere regulation keeps the temperature and atmospheric gases stable
• hydrological cycle intercepts water and increases transpiration
• biogeochemical cycles like the nitrogen cycle provides important chemicals for life
• soil maintinance provides nutrients and stops erosion due to roots holding the land together
• interdependance of abiotic and biotic factors provides food
