Vocabulary
a series of chemical reactions that convert the energy in food molecules into a usable form of energy called ATP
Cellular respiration
List the REACTANTS in Photosynthesis.
CO2, H2O, Light energy
List the REACTANTS in Cellular Respiration.
O2, glucose (sugar)
What is the difference in carnivores and omnivores?
Carnivores eat only other consumers and omnivores eat consumers and producers.
What are the 3 main processes in the water cycle?
Evaporation, condensation, and precipitation
the process of a liquid changing to a gas at the surface of the liquid.
Evaporation
What is the main goal of Photosynthesis?
To make food (glucose)
What is the main goal of Cellular Respiration?
To make ATP (energy)
How does available energy change as it moves through organisms in a food chain?
Decreases as it moves up the food chain.
Which type of matter is involved in more than one cycle of matter?
Oxygen (carbon, oxygen, and water cycles)
all the living things and nonliving things in a given area.
Ecosystem
What is the first step of Photosynthesis?
The chloroplasts capturing sunlight.
What is the first step of Cellular Respiration?
Glycolysis (break down of sugars)
What do energy pyramids show?
the amount of energy available in each link of a food chain
What do water, oxygen, carbon, and nitrogen have in common?
They are all cycled through the environment.
process that changes atmospheric nitrogen into nitrogen compounds that are usable by living things.
Nitrogen fixation
What kind(s) of organisms use photosynthesis for energy?
producers
What kind(s) of organisms use cellular respiration for energy?
Nearly all organisms (there are some exceptions)
How does energy move through the environment?
It flows in one direction (not cycled)
How do animals acquire nitrogen atoms?
By eating plants (plants get it from the soil)
a model of energy transfer that can show how the feeding relationships in a community are interconnected.
Food web
What are the sugars produced in photosynthesis used for?
Immediately or stored for plant growth or later use.
What is the energy produced in cellular respiration used for?
To power all cellular processes.
Explain the difference in a food chain and a food web.
A food chain models energy flow through feeding relationships and food webs show how food chains are interconnected.
How does matter move through the environment?
It is constantly cycled
