Neither process works at low temperatures.
Both involve the transfer of substances between animals, plants , and the Earth
Both involve the transfer of substances between the earth and outer space.
How do animals add carbon dioxide to the atmosphere?

The food web shows
many possible interactions and feeding relationships beween the organsims in the ecosystem
a nice picture of what lives in the ecosystem
the symbiotic relationships
the keystone species
The energy pyramid is a triangular shape because
90% of energy is lost to heat, movement, and survival, and only 10% of energy goes to the next level
People see the top of the pyramid so it is important to know the keystone species.
10% of energy is lost to heat, movement, and survival, and only 90% of energy goes to the next level
the top of the pyramid is the pinnacle organism of an ecosystem

Why is nitrogen essential to the growth of a fungus, but not to the spread of rust?
A fungus grows much faster than rust
A fungus is a living organism, while rust is not
A fungus needs less oxygen than rust
A fungus cannot grow on metal, while rust can
What can you infer from the fact that nitrogen gas is useless to animals?
Animal cells can only use nitrogen when it's combined with other elements
Animal cells cannot process gases before they are converted into liquids and solids
Animal cells do not require nitrogen to function
Animal cells only require nitrogen after the death of the animal
Which of the following most accurately describes the path of a nitrogen molecule through the environment?

It moves through the environment repeatedly, and always in the same order
It moves through the environment repeatedly, but not necessarily in the same order
It moves through the environment twice, then disappears
How does carbon become locked inside the earth?
Tree roots expel carbon into the soil as they grow
Humans use machines to pump carbon dioxide into large underground tanks
