Matter is...?

Matter is anything that has mass and takes up space

100

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

200

Energy is...?

Energy is the ability to do work.

True or False: Food Chains and Food Webs are the same thing?

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)

300

The path of energy in an ecosystem?

IN AN ECOSYSTEM, ENERGY FLOWS FROM THE SUN TO PRODUCERS AND THEN FROM PRODUCERS TO CONSUMERS

300

How do producers get energy?

They get their energy from the sun.

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: E. Unlimited lemming population growth

Unlikely: Habitiat can only support limited amount of lemmings before theres not enough resources.

What is glucose and where does it come from?

Glucose is sugar that comes from the food we eat.

400

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.

    fungi

        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.
