5 True/False questions
productivity → Long chains of organic molecules called amino acids
landscape ecology → Potential energy held in the bonds between atoms. Potential energy is changed into kinetic energy to produce motion, action, and heat.
hydrocarbons → Contain only carbon and hydrogen, Make up fossil fuels,
The simplest hydrocarbon is methane (natural gas),
Can be a gas, liquid, or solid
flux → Movement of nutrients among pools. Can change over time.
pools → The smallest components that maintain the chemical properties of the element
