Name one producer in a food web.

What is algae in an aquatic system, or is any plant/grass in a terrestrial system?

Did you name one?

100

What do decomposers do?

What is breakdown detritus and organic matter into simple minerals?

100

Name one way the geosphere can affect the biosphere?

A volcano erupting (geosphere) can put ash into the air (atmosphere), blocking sunlight and affecting plants (biosphere)

100

Where does all the energy in an ecosystem originate from?

What is the sun?

100

Is air a source of matter or energy?

Air is a gas.  Gas is matter because it occupies space and has mass.

200

Name one decomposer in the food web.

I'd like you to please use your study guide.

What is a Worm or bacteria?

200

True or False: Wolves are decomposers.

What is false?

200

What system throws ash into the air after a volcanic eruption?

What is the geosphere? (geosphere - earth systems)

200

Who uses the sun's energy first?

Who are producers (plants)?

200

Is sunlight a source of matter or energy?

Sunlight is a source of energy.  Sunlight's energy fuels photosynthesis in plants.

300

Name one consumer in a food web.

Use your study guide to help you.  The group will decide if your answer is correct.

300

Name two decomposers.

What are worms and bacteria?

300

What natural event connects the atmosphere (gases surrounding the Earth) and the biosphere (ecological systems involving living organisms)?

What is ash from a volcano going into the air (atmosphere), blocking sunlight and affecting plants (biosphere)

300

What happens to the energy when a herbivore eats a plant?

What is the energy goes from the plant to the herbivore (primary consumer).

300

Is food a source of energy, matter, or both?

What is food is both matter and energy?

400

What type of organism is missing if there is no recycling of nutrients?

What is a decomposer?

400

How do fungi help the environment?

What is they act as decomposers? 

400

How does erosion affect organisms living in the sand?

What is destroying their habitat and their food sources?

400

How does a secondary consumer get energy from the sun? Use the food web in question 1 of your study guide to explain.

The grass(producer) gets its energy from the sun, the chipmunk(primary consumer) eats the grass and gets the sun's and the grass's energy,  the bear (secondary consumer) eats the chipmunk, getting the chipmunk's, the grass's, and the sun's energy.

400

Is water a source of energy or matter?

What is matter? 

500

Use the food web on question 2 in your study guide.  What happens to the snails if the frog population increases?

What is a decrease? Because they are a food source for the frogs, and more frogs means eating more snails.

500

Why are decomposers important to plants?

What is by breaking down dead organic matter and releasing nutrients back into the soil where plants can use it to grow.

500

What are the Earth's systems? (land, water, air, living things)

What are the geosphere (land), hydrosphere (water), atmosphere (air), and biosphere (living things)?

500

In what order does energy flow to the frog? (Use the food web in question 2 of the study guide.)

2 correct answers:

grass - snail - frog   

grass - grasshopper - frog

500

How do plants use matter and energy from the environment?

What is plant's use sunlight (energy) and water(matter) from the environment to produce sugar, food for the plant.
