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
Use the picture in google slide show
What is the ecosystem?
It has 4 distinct season. Trees lose their leaves in fall and grow them back in spring.
Temperate deciduous forest
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?
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.
It is found in northern latitudes. It has thick forest. Most of the trees are evergreens. It has long cold winters and short summers.
Tiaga / Boreal forest
Why are controlled variables important in an experiment
They keep the experiment fair and accurate.
What 2 things does the plant make?
Glucose (food / sugar) + oxygen
Use the food web in google slide show.
In the desert food web, what are the primary consumers?
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
If you and your classmate do an experiment but get different results, what should you do next?
This was a question on last week's homework!!!!
Make sure you both did the experiment the same way.
1. What 2 colors do plants use the best to make their food?
2. What color do plants not use? Why don't they use it?
1. Plants use blue and red light the best.
2. Plants do not use green light. The reflect it.

In the desert food web what are the secondary consumers?
What are the tertiary consumers?
Secondary: tarantula / scorpion / lizard / snake
Tertiary: Hawk and fox
Which of these things is an ABIOTIC factor.
Coral reef / Decomposers / Elevation / Forest
Elevation
Use the picture in google slide show
It is found in northern latitudes and at high elevations in the mountains. There are very few trees. It is cold most of the year. The soil is often permafrost.
Tundra
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
Use the food web in google slide show. The words are not on the picture!!!!
In the desert food web, what types of organisms supply energy to everything?
What types of organisms return all the matter back into the soil and the food web?
Producers 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.
Use the picture in the google slideshow.
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 spring.
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
