What's the MATTER with all this ENERGY?
Matter is...?
Matter is anything that has mass and takes up space
What is an example of a consumer?
Any organism that consumes another organism for energy is a valid answer.
Lemmings are a species of rodent that live in Arctic regions. Snowy owls and arctic foxes are predators of lemmings. A female lemming can give birth to as many as 11 young at a time. They can have a new litter of young every six weeks. As a result, the lemming population could increase exponentially in a very short period of time. Consider what would happen within the Arctic regions as the lemming population grows.
Unlikely or Likely to happen: A. Increased food resources for lemmings
A. Unlikely: Population increase and compete for food , decreases in food resources.
H2O is...
Water
Energy is...?
Energy is the ability to do work.
FALSE: A food chain outlines who eats whom. A food web is all of the food chains in an ecosystem.

Consider what would happen within the Arctic regions as the lemming population grows.
Unlikely or Likely to happen: C. Limited space for shelter
Likely: Population will increase and compete for space. Decreasing amount of available space.
How many oxygen atoms are in Oxygen?
2 (O2)
The path of energy in an ecosystem?
IN AN ECOSYSTEM, ENERGY FLOWS FROM THE SUN TO PRODUCERS AND THEN FROM PRODUCERS TO CONSUMERS
How do producers get energy?
They get their energy from the sun.

Consider what would happen within the Arctic regions as the lemming population grows.
Unlikely or Likely to happen: E. Unlimited lemming population growth
Unlikely: Habitiat can only support limited amount of lemmings before theres not enough resources.
Glucose is sugar that comes from the food we eat.
How is matter restored through the environment?
Decomopsers break down solid waste when an organism dies
Pick the letters of ALL of the statements that explain why a food web is represented as a web.
A. It shows where different organisms in the ecosystem live.
B. It shows how different organisms are connected to each other.
C. It shows only one path of matter and energy flow in an ecosystem.
D. It shows which organisms would be affected if one population of organisms changed.
B. It shows how different organisms are connected to each other.
D. It shows which organisms would be affected if one population of organisms changed.

Consider what would happen within the Arctic regions as the lemming population grows.
Unlikely or Likely to happen: F. Increase in snowy owl population
Likely: As population increases they supply more food for predators causing increase in preadator populations including snowy owls.
How many atoms are in a molecule? How many molecule are in CO2
2 or more, 1 Carbon atom, 2 Oxygen atom
Matter in an ecosystem is cycled from the environment through organisms and back to the environment again. Number the terms to correctly trace the path one atom might take through a food chain. Start with a mineral and end with decomposition.

shrew
insects
soil mineral
white spruce
red-tailed hawk
1. soil mineral
2.white spruce
3. insects
4.shrew
5.red-tailed hawk
6.fungi
How does energy move through an ecosystem?
Plants use minerals and gases from the air.herbivores get there matter and energy from the plants they eat.carnivores get the energy and matter from the animals they eat.

Unlikely or Likely to happen: A. increase food resources for lemmings
Unlikely: Will compete for available food, so decrease in food resources as population increase.
Describe Photosynthesis in detail
Producers get...
Producers (Plants) get energy from the sun the soil uses the water and the carbon dioxide that we breathe out to give us oxygen.
