the cycling of chemical elements through the living and
nonliving parts of an ecosystem

a source of energy formed from dead plants and animals

What are the two effects on the ecosystem of cutting down the trees in a forest?

the process of water changing from a vapor to a liquid. Water vapor in the air rises mostly by convection. This means that warm, humid air will rise, while cooler air will flow downward. As the warmer air rises, the water vapor will lose energy, causing its temperature to drop. The water vapor then has a change of state into liquid or ice.

a pollutant released into the atmosphere

the precipitation that flows over the surface of the soil

the conversion of nitrogen in the atmosphere to a form that can
be used by plants

water being released from clouds as rain, sleet, snow, or hail.

he precipitation that is more acidic than normal rainwater

the process by which precipitation is gathered into a body of water

a plant that hosts nitrogen-fixing bacteria in nodules on its roots

will eventually drain into creeks, streams, and rivers, adding a large amount of water to the flow

the process that allows green plants to make sugars from
sunlight, water, and carbon dioxide and that releases oxygen into
the atmosphere

swelling on a plant root that contains nitrogen-fixing bacteria

occurs when radiant energy from the sun heats water, causing the water molecules to become so active that some of them rise into the atmosphere as vapor.

the process in cells by which oxygen and glucose are used to
produce energy and carbon dioxide

he process that releases nitrogen from the soil back into
the atmosphere

occurs when plants take in water through the roots and release it through the leaves, a process that can clean water by removing contaminants and pollution.
