Energy Flow 1
This is a sequence that shows how energy and nutrients are transferred from one organism to another in an ecosystem.
What is a food chain?
The building blocks of matter
A CHARACTERISTIC THAT CAN BE OBSERVED OR MEASURED WITHOUT CHANGING A MATERIAL
Physical or Chemical Change - Creation or loss of heat
What is a chemical change
Energy does this as it moves up the energy pyramid.
What is decreases
An organism that eats other organisms because they cannot make their own foods
What is a consumer
Anything that takes up space and has mass
What is matter?
Can be observed and measured only by performing a chemical reaction.
What is Chemical Property
Physical or Chemical Change - shredding paper
What is Physical Change
This organism starts off the food web.
What is a producer?
An organism that makes it's own food from non-living material.
What is a producer?
Two or more atoms joined together
What is molecule
Ability to be drawn out into a thin wire
What is ductile/ductility
Occurs when a substance combines with another to form a new substance - Chemical or Physical Change
What is Chemical Change
True or False - More than 1 animal cannot be eaten by another animal.
What is false
Organisms that feed on decaying matter and helps to return nutrients to the soil.
What is a decomposer?
Atoms are made up of three parts
What are protons, neutrons and electrons
How easily a substance dissolves when mixed with another substance
What is solubility
Physical or Chemical change - melting wax
What is a physical change
True or false - Does the producer start at the beginning of the food web?
What is true
It is the initial source of energy in all food webs and food chains.
What is the sun?
A substance made up of only one type of atom.
What is an element
The temperature at which a substance changes from a solid to a liquid
What is melting point
Physical or Chemical Change - A liquid forms bubbles when it reaches a high temperature.
