The number of different species found in a particular area

What is species richness? 

100

the way two organisms of different species biologically interact in a relationship in which each individual derives a fitness benefit, example is a remora and a shark

What is mutualism? 

100

Of the following it does not increase carbon dioxide: respiration, photosynthesis, combustion, decomposition

What is photosynthesis

100
Any significant amount of water gathered in the ground.
What is an aquifer
100

Energy source whose use is a direct cause of deforestation

What is biomass? 

200

In this stage birth and death rates are HIGH. There is a high infant mortality rate and low life expectancy. The Population is low and stable because of the stable birth and death rates.

What is stage 1 of the demographic transition?

200
An inherited characteristic that helps an organism survive in its environment
What is an adaptation
200

Chemicals occur in higher levels in organisms at higher trophic levels.

What is biomagnification 

200

Water is also delivered very close to the plant's roots, so there is very little runoff.

What is drip irrigation? 

200
The world's most abundant fossil fuel
What is coal
300

Biotic factors in the environment that have an increasing effect as population size increases

What is density-dependent factors? 

300

The two things that Terrestrial biomes are categorized by. 

What is Temperature and Precipitation. 

300

Law that regulates air pollution

What is the Clean Air Act?

300

There are naturally occurring salts in irrigated water.  When land is watered, and the water evaporates, the salts are left on the soil.  Over time, the salts build up and make it difficult for plants to grow.

What is Salinization?

300
The percentage of energy which does not move on to the next trophic level
What is 90%
400
If the population of a country grows at a rate of approximately 5 percent per year, the number of years required for the population to double is closest to
What is 14 years.
400
Example of an ecosystem with the highest net primary productivity
What is the rainforest
400

Caused by VOCs and NOx reacting with water vapor and sunlight. The biggest cause is cars, especially in dry, warm conditions


What is photochemical smog?

400

The breeding, rearing, and harvesting of fish, shellfish, algae, and other organisms in all types of water environments.

What is Aquaculture?

400

Where all biomass gets its energy. 

What is the sun

500
The equation for % growth rate is...
What is {(b-d)+(i-e)}/population size x 100
500

Give an example of a regulating ecosystem service provided by a forest.  

Answers will vary.  Climate regulation via photosynthesis, pulling CO2 out of the air is a good one.

500

The enrichment of bodies of fresh water by inorganic plant nutrients (e.g. nitrate, phosphate). It may occur naturally but can also be the result of human activity and is particularly evident in slow-moving rivers and shallow lakes. May cause large amounts of algal growth.

What is eutrophication

500

As CO2 is stored in ocean water it becomes carbonic acid decreasing the pH of seawater.  

What is ocean acidification? 

500
The primary producers responsible for up to 70% of primary productivity near the ocean surface are
What is plankton
