Estuary
partially enclosed, coastal water body where freshwater from rivers and streams mixes with salt water from the ocean
Permafrost

Polar zone
Temperate zone
Tropical zone
Polar zones - coldest zone
○ Temperate zones - in
between more seasonal
variation
○ Tropical zones -
warmest (near the equator)
what is the ultimate source of energy for all organisms
The sun
What are some examples of abiotic factors?
Jow about biotic factors?
Abiotic - rock, water, the sun
Biotic - bunnies, deer wolves
Why are decomposers important in all food webs ?
They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.
How does an autotroph get its energy? How about hetreotroph?
Autotroph - from the sun
Hetreotroph - by consuming other organisms
What kind of organisms are producers?
Autotrophs, plants, and trees, photo/chemsynthesisers
What is meant by the 10% rule?
At each trophic level, about 10% of the energy is transferred to the next trophic level,and the rest is utilized and lost as heat
