biological productivity - Answer-synthesis of organic materials from inorganic substances by photosynthesis/chemosynthesis what are the inputs & outputs of photosynthesis? - Answer-inputs: water, carbon dioxide, & sun energy outputs: sugar & oxygen (6H2O + 6CO2 + sunlight - > C6H12O6 + 6O2) what are the different types of light penetration in the oceans? - Answer-1. red/orange = turned into heat energy b/c they cannot reach all the way down 2. green/blue/purple = farthest reaching ligh...

List and explain a historical event or influence that had an impact on the development of the modern environmental movement. (1) correct answers Ex: Minimata, Japan In 1956, a chemical company in Minimata Bay released toxic methyl mercury into the waste water. As a result, organisms in the water like fish and shellfish were poisoned due to the contamination. Local people who consumed these fish developed mercury poisoning. This raised awareness about the threat of industrialization and the ne...

What is the carbon cycle? Why is it important? - Answer The carbon cycle is the mouvement of carbon between species, the earth, the atmosphere and oceans. Without carbon, ecosystems would not function and persist over time. Most exchanges involve the ocean. What are the crucial processes in the carbon cycle? Why are they important? - Answer Cellular respiration and photosynthesis. They cancel each other out so that there isn't too little CO2 (causing a frozen earth) or too much CO2 (causi...
