Watershed
This term describes the area of land where all the water that falls in it drains off to a common outlet.
Watershed
This term describes catching fish at a rate faster than they can reproduce, threatening ocean food webs.
Overfishing
These organisms sit at the very bottom of the energy pyramid and get their energy from the sun.
Producers
These organisms, such as fungi and bacteria, are responsible for returning nutrients from dead matter back to the soil.
Decomposers
Is water freezing and evaporating a chemical or physical change?
Physical
This occurs when rainwater washes oil, trash, or fertilizer off the land and into local streams.
Runoff
Humans depend on the ocean for this gas, as phytoplankton produce about 50% of the Earth's supply.
Oxygen
This is the percentage of energy that is actually passed up from one trophic level to the next.
10%
Why are producers at the bottom of the energy pyramid?
Who was credited as the father of the Plate Tectonic Theory?
Alfred Wegener
This is the process where excess nutrients like nitrogen from fertilizers cause a rapid growth of algae, leading to "dead zones" in the water.
Algal Bloom
Humans rely on ocean systems for many things. Name 2 ways!
Food (Fish), Transportation of goods, Recreation, Climate & Atmosphere Regulation, Oxygen, etc....
If a producer level has 10,000 kcal of energy, this is the amount of energy available to the primary consumers
1,000 kcal
What happens to the energy from a dead plant when it dies?
Decomposers break down the plant and turn it into nutrients in the soil.
What kind of boundary causes plates to towards each other?
Convergent
the layer of ground just beneath your feet—like the dirt in your garden—that isn't completely soaked with water
Unsaturated Zone
This type of disaster occurs when liquid petroleum is released into the ocean, coating birds' feathers and blocking sunlight.
Oill spill
Most of the energy lost between trophic levels is released into the environment in this form.
Heat
Carbon dioxide, Water, Sunlight.
Divergent
Rain gardens help rainwater soak into the soil, which helps refill this important source of fresh water stored underground
Groundwater or Aquifer
Name three types of human pollution that ends up in our oceans.
Plastic, Aluminum cans, Glass, etc....
If a tertiary consumer has 5 kcal of energy available, the producer level originally started with this many kcal.
5,000 kcal
What is the chemical formula for glucose?
C6H12O6
How many atoms are there in Ba3(PO)2
7 atoms
