Photosynthesis
What are organisms called that make their own food?
(________ , Consumers, Decomposers)
Producers
What do the arrows in a food chain / web show.
Do not use eat or food in your answer
The arrows show the flow of energy.
What are the living parts of an ecosystem called?
Biotic

Which picture is a temperate deciduous forest and which is a boreal forest? (From yesterday)
Explain how you know.
Left is Deciduous forest has 4 seasons and the trees lose their leaves in the fall.
Right is Boreal is an evergreen (conifer) forest. Trees do not lose their leaves.
What are the metric units of measure for each thing?
Length
Mass
Volume
Length = Meter
Mass = Gram
Volume = Liter
What 3 things go INTO the plant during photosynthesis?
Carbon dioxide + Water + Light
What is the source of energy for all food webs?
The sun is the source of energy in all food webs.
What are the nonliving parts of an ecosystem called?
abiotic
Use the picture in google slide show.
Why do the trees that grow in a Boreal ecosystem make the soils there bad?
The trees don't lose their leaves in the fall so decomposers are not breaking them down and putting nutrients back into the soil.
Why are controlled variables important in an experiment
They keep the experiment fair and accurate.
What 2 things does the plant make during photosynthesis?
Glucose (food / sugar) + oxygen
Use the food web in google slide show.
In the desert food web, what are the primary consumers (plant eaters)?
Insects / lizards / rodents
Use the tide pool picture in google slide show.
What 2 abiotic factors work together to create a tide pool?
High and low tides
Rocks

It is a living organism found in warm, shallow ocean water. It provides shelter for many species of fish.
Coral reef
Where does the force of gravity pull everything?
Gravity pulls everything toward the center of the earth. To you it is pulling down.
What TWO things make most of the mass / weight of a plant?
Carbon Dioxide (CO2) and Water (H2O).
They are what make glucose which the plant uses to make itself and to get energy

In the desert food web what are the secondary consumers?
What are the tertiary (apex predator) consumers?
Secondary: tarantula / scorpion / lizard / snake
Tertiary: Hawk and fox
Which of these things is an ABIOTIC factor.
Coral reef / Decomposers / Elevation / Forest
Elevation

Why can you find a cold weather ecosystem like alpine tundra at the equator?
Because it is at a high elevation in the mountains so it is cold.
Use picture in google slide show to help you.
Carbon dioxide = CO2
How many molecules are in the picture?
How many atoms are in the picture?
How many elements are in the picture?
1 Molecule
3 atoms (1 carbon atom + 2 oxygen atoms)
2 elements (carbon and oxygen)
What are two reasons photosynthesis is responsible for all life on earth?
1. It provides energy
2. It makes oxygen
In ALL food webs, what types of organisms supply energy to everything?
What types of organisms return all the matter back into the soil and the food web?
The Sun and Producers (plants) supply the energy
Decomposers return the matter back to the food web.
Explain how shelter can be both an abiotic and/or biotic factor in an ecosystem.
Shelter can be something non living like soil or a rock.
Shelter can be a living thing like a coral reef or a tree.

How are temperate and tropical different?
Describe location and climate.
Is this biotic or abiotic?
Tropical is near the equator so it is hot most of the year.
Temperate is not near the equator so it has 4 distinct seasons.
It is ABIOTIC
Describe the tilt of earth's axis in summer and winter.
What month is the beginning of each season.
winter / spring / summer / fall
summer tilted toward the sun
winter tilted away from the sun
winter = December / spring = March
Summer = June / Fall = September
