3. Biotic & Abiotic Factors in the Ecosystem
______ = Life Biotic factors: Living things
____= Not Abiotic factors: Nonliving things
Abiotic Factors
Biotic Factors
ECOSYSTEM

4. Habitat & Niche _____________ = The area where
an organism lives. Its address.
_______________ = The habitat and what the organism does in its habitat. Its job.

5. An organism’s niche includes:
The type of food it eats
How it gets the food
What eats the organism
When and how it reproduces
Physical conditions it needs to survive
Bullfrog example p.91

6. Can two different species share the same niche?
__________________
But, different species can occupy similar niches.
Three species of warblers and their niches

7. Can all kinds of organisms live in every biome?
___________________
Species are adapted to survive in certain biomes.
_____________________: an inherited condition that increases an organism’s ability to survive and reproduce.

8. Grassland Adaptations
Grasses have pollen that is spread by the ___________, therefore the flowers are not very showy. 
Roots are one of the most critical parts of the plant in a grassland.  The roots do much of the competing for space, nutrients
and water, and the roots may
hold most of the biomass of the
plant.
Grasslands lack the trees and heavy bush to hide many creatures. Because of the open landscape and the widely spaced trees, grasslands are home to large herds of grazing mammals such as the zebra and bison.
Many animals are active only during the rainy season.

9. Rain Forest Adaptations
Some animals became very ______________.
Parrots and toucans eat nuts so they developed big strong beaks to crack open the tough shells.
Plants must grow tall to reach the sunlight
Roots do not need to be planted in the soil
take their food from air and water
all around.
Bromeliad and Epiphytes (non-parasitic plant growing on another living plant)

10. wildflowers grow on forest floor
Animals living within this biome must adjust to ____________ winters and hot summers
Winter and summer coats (shed)
Hibernate or migrate
keeping active all winter.
wildflowers grow on forest floor
________________ in the spring before trees leaf out and shade the forest floor
many trees are deciduous (they drop their leaves
in the autumn, and grow new ones in spring). 

11. Desert Adaptations Desert plants have two main adaptations:
Ability to collect and store _______
Features that ____________ water loss
Desert rodents have special adaptations so their kidneys conserve water.
The white hairy surface of the Old Man Cactus
helps the plant reflect the hot desert sun.

12. Tundra Adaptations
The frigid cold and deep snow makes life in the tundra very difficult. 
Some have grown thick fur which turns white in the winter. Others find a place to hibernate during the winter months.
Tundra plants are small (usually less than 12 inches tall) and low-growing due to lack of nutrients
being close to the ground helps keep the plants from freezing, and because the roots cannot penetrate the permafrost.
Plants are dark in color—some are even red,
this helps them absorb solar heat.
