When all the trees in a forest are cut down at once.
What is clear cutting?
100
What type of land management grows crops and raises animals?
What is agriculture?
100
Topsoil that is moist, and contains nutrients.
What is fertile soil?
100
Too many nutrients get into water ways causing phytoplankton to bloom, die and decay, using up oxygen and killing fish and other organisms.
What is eutrophication?
200
A way to protect fish populations from becoming depleted.
What are laws to protect fiseries?
200
Clear cutting forest exposes massive area of soil, causing this problem.

Two main nutrients that cause eutrophication.
What are nitrogen and phosphorous?
300
A method where fish are grown in controlled areas to reduce demand for wild caught fish.
What is aqaculture?
300
This method of clearing forest helps to protect habitat.
What is selective cutting?
300
This type of land management removes oil, minerals, coal & natural gas from the ground.
What is mining?
300
Planting different crops in the same area, like legumes, to help replenish nutrients in the soil.
What is crop rotation?
300
These organisms can be microscopic plants make the basis of the food chain in waterways.
What are phytoplankton?
400
Catching fish faster than they can reproduce.

This plant is a major class of phytoplankton.
What is algae?
500
When the entire population of and organism is wiped out.
What is extinction?
500
This is not considered to be a benefit of clear cutting.
What is habitat protection? or What is erosion?
500
Trees planted along stream banks to reduce pollution from runoff and erosion.
What is a buffer.
500
Allowing left over food, (fruits, grains & vegtables) to decompose and make fertilizer for the soil.
What is composting?
500
Floating mats of phytoplankton block this important resource from reaching organisms in the water.
