REVIEW SHEET FOR THE BIOMES
& FOOD CHAINS
NAME__________________________________
REVIEW SHEET DUE THE DAY OF TEST
C
TU
1. First name all of the land biomes:
TA
TRF
G
D
TDF
2. LAND BIOMES: MANY REPEATS!
Name of the
Characteristic of biome
biome/temperature zone
Sunlight hits this temp zone directly
Sunlight hits this area at a very low angle
Hot daytime, could be cold at night, very little rain
Most precipitation of all the biomes
Permafrost, frozen soil, no trees
Lowest temperatures, high winds
Deer, squirrels, chipmunks, skunks, opossum, trees drop
leaves
Has 4 distinct seasons
High temperatures, high rainfall all year, hot and humid
Evergreen trees, pine trees, needles, cone-bearing trees
About 400 cm of rain yearly (lots of rain!!)
Has glaciers
Temperate biomes (temperate areas)
Tropical biomes (hot areas)
Polar biomes (old areas)
WE live in this biome
Greatest diversity of life on LAND
Too cold for me to go swimming there, but people do go in the
lakes, NOT the coldest biome
Oak, maple trees with leaves on my lawn right now
“Bread basket” biome of this country
Oat, barley, wheat found in abundance in this biome
Cactus, reptiles in abundance like snakes, lizards, etc. Very
dry, rocky
Leaves drop off trees in fall
Zebra, hippo, bison found in this biome
This biome found in states of Washington, Oregon, Northern
Maine
California big fires sometimes
3. There are 3 temperature zones of Earth. Label the zones in the diagram. Label the
sunlight: direct, least, most. Now put the biomes into the zones (C, T, T, TRF, TDF, D,
G). Use their full names, the letters are only a hint! Refer to Wikis for maps or Google
“map of biomes” for a reference.
4. Water biomes: Name four water biomes:
a. _____________________
b. _____________________
c. _____________________
d. _____________________
5. Complete the table:
Name of water biome/s
Characteristics
Over fishing is a threat
Salt water
Fresh water
Brackish water (part salt, part fresh water)
Ponds, rivers, lakes
Rivers meet salt water
Covers 70 % of earth’s surface
Snorkeling because there is food and lots of fish here
Found very deep in the ocean, dark and cold water
except where these are found
6. Organisms that can make their own food are called ________________________
7. Organisms that have to eat other organisms for energy are called
______________________________
8. Organisms that only eat plants or other producers are called
____________________________
9. Organisms that are meat eaters are called ___________________________
10. Organisms that can eat either meat or plants are called
__________________________________ (like most of us!)
11. Define a “trophic level”.
12. Where are producers found on a food chain/web, energy pyramid, pyramid of
numbers, and biomass pyramid? (all the same answer)
13. Reference #12- why are producers located at that position??
14. What are decomposers and why are they important?
15. Create a food web with the following organisms. Remember to draw the arrow
AWAY from the prey towards the predator receiving the energy. Look up any
animals you do not know.
Hawk, Grass, shrew, snake, grasshopper
______________
_____________ _____________ ____________ ____________
16. The animal that is hunting or consumer is called the _______________________
17. The organism being consumed is referred to as the ________________________
18. Draw the “Energy Pyramid” with 4 levels and add the following labels:
producers, primary consumer, secondary consumer, tertiary consumer, 1st trophic
level, 2nd trophic level, 3rd trophic level, 4th trophic level. Remember to add
“calories” to the web to represent energy.
19. Draw a biomass pyramid with 4 levels and add the following labels: producers,
primary consumer, secondary consumer, tertiary consumer. Remember to add mass
units to show change in mass up the pyramid.
20. Draw a pyramid of numbers with 4 levels. Put in the producers, primary
consumers, secondary consumers, and tertiary consumers. Add numbers to
demonstrate numbers of organisms going up the pyramid.
21. What is the difference between a food web and a food chain?
22. What is biomagnification and why is it a concern? (remember the idea about not
eating fish/sushi too often in a week, why?!)
23. Use the following food web to answers the last two questions:
a. What effect would removing phytoplankton have on this food web?
b. What effect would removing killer whales have on the food web?
