1) Living factors are called? a) biotic b) abiotic c) food webs d) ecosystems 2) When water vapor is released from plant leaves to the atmosphere: a) condensation b) perspiration c) transpiration 3) Water changes from liquid to gas due to heat energy absorbed from the sun. a) evaporation b) condensation c) precipitation d) transpiration 4) Water in the atmosphere cools and changes from water vapor to liquid water. The air can become saturated and form clouds. a) evaporation b) condensation c) precipitation d) transpiration 5) A waste product of respiration. a) sunlight b) carbon dioxide c) glucose 6) Form that carbon is found in the atmosphere a) carbon dioxide b) diamonds c) fossil fuels 7) Process that takes in Carbon dioxide from the air. a) decomposition b) combustion c) respiration d) photosynthesis 8) When living things die, this process releases CO2 a) decomposition b) combustion c) respiration d) photosynthesis 9) Water flows downhill and ends up in rivers and streams - and flows to the ocean. a) Runoff b) Rain c) Snow 10) Water that seeps beneath the surface (infiltrates) and flows through porous rocks. a) condensation b) precipitation c) groundwater 11) When water moves into the roots of plants, moves through the plant body and evaporates off the leaves. a) clouds b) transpiration c) precipitation 12) Fossil fuels have taken millions of years to form. When they are combusted (burned), what gas is released? a) carbon dioxide b) water vapor c) oxygen 13) Plants obtain the carbon they need during photosynthesis from? a) oxygen b) water vapor c) carbon dioxide 14) The process that releases energy from the bonds of glucose sugars (carbohydrates) and produces water and oxygen as waste products. a) combustion b) respiration c) photosynthesis 15) This process is mostly done by fungi and bacteria and is the breakdown of organic matter; releases carbon dioxide and water. a) decomposition b) evaporation c) photosynthesis
