It is stable or growing very slowly
Explain how deep, global, ocean circulation currents form and cool the atmosphere at the equator.
Ocean water absorbs the heat from the atmosphere. As it:
A) Evaporates creating saltier, denser water and
B) As currents push the water north it cools and gets denser
It sinks and then flows until it resurfaces at areas of upwelling where it is heated again.

A city with a population of 1,000,000 people saw 300,000 births and 100,000 deaths with 5000 people moving away from the city and 20,000 moving into the city. What is the population growth rate?
(300 + 20 - 100 - 5 ) / 10 = 21.5%

What is the Dysphotic zone?
How is industrialized agriculture different from traditional agriculture (give me 2)
Industrial focuses on mono-crops over multicropping
Industrial uses synthetic fertilizers and pesticides to increase yield over manure and water
Industrial uses heavy machinery for labor over people

The situation in the previous question may cause farmers to make a decision as to whether they will stay in this farming profession or find a new career. This type of decision is primarily based on
Cost-Benefit Analysis
You start a light bottle/dark bottle measurement on algae Species X with 10 mg/L of DO in both bottles. You let the bottles sit for one week so that photosynthesis and respiration rates can be calculated. At the end of one week, you have 7 mg/L of DO in your dark bottle and 12 mg/L of DO in your light bottle. What is the NPP, GPP, and respiration?
NPP = 2 mg/L
GPP = 5 mg/L
R = 3 mg/L
