Energy & Matter 1
Food.
Where do organisms get energy from?
The process that some plants use to convert light energy from the Sun into food energy.
What is photosynthesis?
A model showing how food energy moves through an ecosystem.
What is a food chain?
It shows the amount of energy available at each step of a food chain.
What does an energy pyramid show?
Cell processes.
What does all life on Earth need energy for?
Herbivores are animals that eat only producers, such as plants.
Omnivores, such as human beings, eat both producers and consumers.
Carnivores, such as lions, eat only consumers.
Detritivores, including some insects and fungi, eat dead plant or animal material.
What are the four types of consumers?
A model that shows several connected food chains.
What is a food web?
Matter is the physical material that makes up the world around you.
What is matter?
When one organism eats another, the energy from the eaten organism is transferred to the organism that ate it.
How does energy move from one organism to the next in an ecosystem?
Other organisms get energy from producers by eating producers or other organisms that have eaten producers.
How does energy move from a producer to other organisms?
By noticing what different organisms eat.
How can you study how energy travels through a community?
Water cycle, oxygen cycle, and carbon cycle
What is the three matter cycles described in the textbook?
The Sun.
What is the original source of energy of foods?
Consumers cannot make their own food and get energy by eating other organisms.
How do consumers obtain energy?
A food web is a network of food chains that move energy throughout an ecosystem.
How are food chains and food webs connected?
Water takes the form of liquid water (liquid), water vapor (gas), and snow (solid).
What forms does water take in the water cycle?
Producers change the energy available in their environment into food energy.
How do producers obtain energy?
Chemosynthesis is the chemical process some producers use to change chemical energy into food energy.
What is chemosynthesis?
There is less available energy because some of the food energy is converted to thermal energy.
Why is there less available food energy in the later stages of the food chain?
Producers and consumers are part of the oxygen cycle.
What organisms are part of the oxygen cycle?
