Describing Matter and Energy
It has mass and takes up space
What is matter?
An organism that uses energy and matter from the environment to make its own food.
What is a producer?
A process in which atoms are rearranged to produce new substances.
What is a chemical reaction?
A process that uses oxygen to release the energy stored in food molecules.
What is cellular respiration?
A pathway that energy and nutrients can follow through an ecosystem.
What is a food chain?
They are the building blocks of matter.
What are atoms?
An organism that gets its energy from breaking down the remains of other organisms that have died.
What is a decomposer.
It uses symbols to show the relationship between the starting materials and the materials produced in the chemical reaction.
What is a chemical equation?
Producers, consumers and some other types of organisms use this.
What is cellular respiration?
Interconnected food chains are called these.
What is a food web?
It is made up of two or more atoms.
What is a molecule?
An organism that gets its energy and matter from eating other organisms.
What is a consumer?
They are the building blocks of living things.
What are carbon molecules?
The first stage of cellular respiration takes place here.
What is the cytoplasm?
A representation of energy available at each level of a food web.
What is an energy pyramid?
Two hydrogen atoms and one oxygen atom makes this.
What is water?
Without these, matter that makes up organisms would not be recycled back to the nonliving environment.
It can form bonds with other carbon atoms or with different atoms
What is a carbon atom?
The second stage of cellular respiration takes place here.
What is the mitochondria?
It is essential to life becasue all cells are made up of these molecules.
What is the carbon cycle?
Oxygen and carbon are these.
What are elements?
Three things that use energy from sunlight to make sugar molecules.
What are plants, algae and bacteria.
A series of chemical reactions in which the cells of producers use energy from the sun to make carbon-based food molecules called sugars.
What is photosynthesis?
Energy is released these stages of cellular respiration
What is all stages?
Cells use this to build many molecules.
What is nitrogen?
