Animals that eat the plants

Into the atmosphere

increase nitrogen through fertilizers

increase nitrogen through smoke

increase nitrogen through farm animal waste

increase nitrogen recycling

increase nitrogen through saving energy and using renewable engery sources

process of transpiration in autotrophs

ability of consumers to move from place to place

nitrogen-fixing bacteria and lightening

evaporation of water from Earth's surface

Deforestation increases the number of plant and animal species by destroying habitat

Forest clearing is often followed by land development, which often leads to increased noise pollution

Deforestation reduces the amount of oxygen in the atmosphere, which depletes the ozone layer

Forest burning releases CO₂ while decreasing oxygen, which disrupts cycles

turning CO2 from the atmosphere into organic molecules

respiration: releasing CO2

decomposing CO2 in the soil

photosynthesis: absorbing CO2

car exhaust

fungi

rain

bacteria

denitrification

ammonia

nitrogen fixation

nitrogen composition
