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

at its birth? Molten Rock 6. Why was it important for the Earth to be at the right distance from the sun-not too far‚ not too near? So it could conserve water in liquid form 7. 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
Premium Earth Precipitation Water cycle
together like a machine. Everything plays into one another. For example: the water cycle. The water evaporates from the body of water here on Earth. Then there is condensation and it rains‚ which is also known as precipitation‚ and then the collection of water goes back into the lakes‚ rivers and oceans; where it starts over again. This water cycle plays in part with the plant life and the food chain. Without this water cycle there would not be plants. Without plants there would not be any food for

the night and wanting a glass of water‚ you go to the tap and instead of fresh clean water you get yellow‚ cloudy‚ oily water that smells of chemicals. Would you drink it? Those that live near natural gas hydro-fractured wells have had to ask themselves that question. Hydraulic fracturing or fracking‚ as it’s commonly called‚ is a process of extracting natural gas from deep within the earth’s surface by drilling. Once a well is drilled‚ millions of gallons of water‚ sand and chemicals are injected

gasses are released during a volcantic eruption including water vapor. Water vapor was the main contributor to where the primary ocean waters originated from. This is because the water vapor condensates after being gassed out of the volcanoes‚ once the condensation occurs then precipitation is created. 3) Describe the hydrologic cycle as if you were a particle of water going through it. If I were a particle traveling though the hydrologic cycle I would being by floating on top of the ocean and soaking
