A spaceship has a unique life support system providing air‚ water‚ food‚ shelter and companionship. Earth also has its own life support system which includes the atmosphere‚ hydrosphere‚ lithosphere and biosphere. Air & Protection Both the earth and spaceships provide air and shelter by themselves.

All living organisms on earth rely on another living organism. If we allow factories to ruin our enviorment we will not only be ruining earth‚ but ourselves. If factories kill the animals we eat then we may starve to death. As you see killing the animals ruins our life cycle. It hurts us as well. We rely on

“Early one morning words were missing.” When I first read Short Talks‚ I had difficulty understanding why Anne Carson wrote about what she did‚ and thought that some words must have been missing. I was confused as to how they all fit together and it was only after further consideration that I came to see how the sections unite into one cohesive piece. Anne Carson’s Short Talks is a series of short reflections on different subjects that at first do not seem to be related‚ but through her use of cyclical

Ecology EQ’s 2. Abiotic and biotic components influence each other. For instance‚ temperature (abiotic factor) can make plants (biotic factor) reproduce more or reproduce less. Also water‚ an abiotic factor‚ has an effect on how animals‚ a biotic factor‚ survive in certain areas of the world. 3. Because a different niche allows multiple species of organisms to coexist. If all organisms had the same niche‚ then there would be heavy competition for food‚ shelter‚ etc. Having different niches gives

terrarium’s walls‚ many different natural processes may be observed: photosynthesis‚ respiration‚ and the water cycle. The water in the terrarium is constantly recycled‚ passing from liquid form to gas and back again. As the moisture in the air condenses on the glass walls‚ it returns to the soil and is absorbed by the plants’ roots. Objectives: 1. To determine the stages of the water cycle 2. To observe‚ compare and contrast their observations with other groups. 3. To compare the actual

How is the water cycle described? The water cycle is described as veins of the body or branches of a tree. 8. How did the ocean get salty? Water tore minerals from the rocks and gradually added them to the rivers that fed the oceans that became heavy with salt. 9. What is shared by every life-form

Lab 5 – Weather and Climate Change Lab 5 - Demonstration 1: Modeling the Water Cycle POST LAB QUESTIONS 1. Which water cycle processes are represented in this model and by what components? Answer = Evaporation‚ condensation‚ sublimation‚ and precipitation. 2. Which processes are not represented? How could the model be altered to include these processes? Answer = Transpiration‚ surface run-off‚ infiltration‚ and percolation. With or by adding sand and possibly plants to the assignment

Interconnection of Natural Systems Having all of the natural systems interconnected does not help to our existence in the planet. By the interconnection of natural systems I mean the connection between the nutrient cycles‚ the trophic levels‚ weather‚ etc. A natural system is defined as one that “exists in nature and consists of all the materials that are physical and biological and the interrelated processes occurring to these materials that constitute the world and provide the physical basis
