______Population______Biotic factors______
______Species______
14. What are the things that an organism’s habitat MUST provide for the organism? There are three (3)!
_____Food, water, shelter–without any one of them, there would be death!______
15. You visit a desert ecosystem in late spring. Use what you know about deserts to complete the following…
List 3 biotic features.List 3 communities.List 3 species.
(anything living, specific or broad)(Broad term)(specific term)
__mammal______mammal______Elf Owl______
___Saguarocactus______plant______Saguaro Cactus______
___plant______reptile______bearded dragon__
List 3 abiotic features.List 3 populations.
(anything nonliving)(mid-sized term)
__temperature______bird______
__sand, air, little rain______cactus______
___rocks, sunlight______lizard______
16. What is the difference between a Biome and an Ecosystem?
A Biome is a large area that has similar temperature, rainfall, organisms, etc. An ecosystem is a
smaller, more specific part of a Biome. For example, if the Biome is desert, the ecosystem could be the Sahara desert ot the Mojave desert.
17. Place the following terms in order, starting with the “largest”. Give an example where appropriate.
Ecosystem, species, biome, community, biosphere, population. Try to keep a common theme.
(think of your ecosystem bells! Use them as your examples!!)
a. ____Biosphere______
b. ____Biome______example ______Desert______
c. ____Ecosystem______example _____Mojave Desert______
d. ____Community______example _____Plants______
e. ____Population______example _____Cactus______
f. ____Species______example _____Saguaro cactus______

Lesson Review pg. 15
1. Biotic - Living factors only. Abiotic – non-living factors only
4. A biome is a large region with similar climate and organisms. An ecosystem is a smaller more
specific piece of an ecosystem. For example: biome = desert, ecosystem = Mojave Desert
5. (Complex) biome – ecosystem – community – population – species (simple)
7. Climate, food supply, available shelter – how can a Polar Bear live in the desert? It needs the cold
and is adapted to the food that comes with that type of climate.
8. Very little rain would lead to a drought – many species would die because they didn’t have enough
water to live. Those species deaths would cause other species to move out or die themselves. The entire ecosystem could become a different ecosystem if the drought lasted long enough.
