Air surrounding the Earth.
mixture of mineral and rock particles, dead organisms, air, and water. It is formed on the Earth's crust and supports plant life.
nitrogen fixation
Types of bacteria in teh soil that change nitrogen gas into a nitrogen form plants can use.
energy pyramid
amount of energy available at each feeding level in an enviorment
percentage of nitrogen in earth's atmosphere
percentage of oxygen in Earth's atmosphere
percentage of carbon dioxide in Earth's atmosphere
process that uses carbon dioxide
process that uses oxygen
water and its importance
Without it, many important processes cannot be done/ most organisms are at least half of this fluid, which is a major one for all organisms
soil is abiotic and biotic
It has decaying organisms and rock and mineral particles
sunlight and its importance
It is the main energy source for all life on earth
temperature and precipitation
Most important components of climate
rain shadow effect
Wind is blown up and cooled to where it is released as precipitation. When the cool air finishes crossing the mountain, it has lost most of its moisture.
converts light energy into chemical energy
how photosynthesis converts energy
hydrothermal vents
the vents chemosynthesis creates energy in
how chemosynthesis creates energy
this process creates energy when nutrients in teh hot water feed chemosynthetic bacteria that feed the consumers in a hydrothermal vent
a food web is many different food chains
the relation between food webs and food chains
