Science Review

This term describes the area of land where all the water that falls in it drains off to a common outlet.

Watershed

100

This term describes catching fish at a rate faster than they can reproduce, threatening ocean food webs.

Overfishing

100

These organisms sit at the very bottom of the energy pyramid and get their energy from the sun.

Producers

100

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

200

This occurs when rainwater washes oil, trash, or fertilizer off the land and into local streams.

Runoff

200

Humans depend on the ocean for this gas, as phytoplankton produce about 50% of the Earth's supply.

Oxygen

200

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?

Plants produce the most energy for feeding organisms in an ecosystem.

Who was credited as the father of the Plate Tectonic Theory?

Alfred Wegener

300

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

300

Humans rely on ocean systems for many things. Name 2 ways! 

Food (Fish), Transportation of goods, Recreation, Climate & Atmosphere Regulation, Oxygen, etc....

300

If a producer level has 10,000 kcal of energy, this is the amount of energy available to the primary consumers

1,000 kcal

300

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.

300

What kind of boundary causes plates to towards each other?

Convergent 

400

the layer of ground just beneath your feet—like the dirt in your garden—that isn't completely soaked with water

Unsaturated Zone

400

This type of disaster occurs when liquid petroleum is released into the ocean, coating birds' feathers and blocking sunlight.

Oill spill

400

Most of the energy lost between trophic levels is released into the environment in this form.

Heat

400
What are the 3 reactants in photosynthesis?

Carbon dioxide, Water, Sunlight. 

400
Mid-ocean ridges, Rift Valleys, and Sea Floor-spreading are all examples of what kind of plate boundary?

Divergent 

500

Rain gardens help rainwater soak into the soil, which helps refill this important source of fresh water stored underground

Groundwater or Aquifer

500

Name three types of human pollution that ends up in our oceans. 

Plastic, Aluminum cans, Glass, etc....

500

If a tertiary consumer has 5 kcal of energy available, the producer level originally started with this many kcal.

5,000 kcal
