reservoir a natural or artificial place to store water Watershed a region that drains into a certain water body Aquifer underground rocks and formations that are able to hold groundwater confined aquifer an aquifer with a surface that keeps water from infiltrating, so the water must enter the aquifer at a point farther away fossil water water trapped in ancient aquifers formed 12,000 years or more ago groundwater water that has infiltrated below the groun...

BIO 123 EXAM 2 ESSAY QUESTIONS AND ANSWERS 1. Use the first and second laws of thermodynamics to explain why each ecosystem needs a continuous supply of solar energy. The first law says that energy can not be created or destroyed. The second law says in any energy conversion, some energy is wasted as heat; moreover, the entropy of any closed system always increases. Energy flows through ecosystems in one direction, typically from the sun, through photosynthetic organisms including green plan...

McMaster Biology 1M03 Exam Q&A with Accurate solution What is the carbon cycle? Why is it important? - 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? - Cellular respiration and photosynthesis. They cancel each other out so that there isn't too little CO2 (cau...

ozone construction exists as 3 basic forms - Answer- o - oxygen atom o2 - oxygen molecule o3 - ozone molecule - toxic, unstable gas, protects us from UV sunlight sunlight strikes o2 molecules and splits them, the floating o atoms will "float" and come into contact with o2 to form - Answer- o3- ozone molecule the stratosphere is approx. how far away above earths surface - Answer- 15 to 50 km normally there is a balance between the ___________ and ___________ of o3 - Answer- destructi...
