Feb/21/13 Ecosystems – Lab #4 Purpose: To study the interactions between living and non-living things within the ecosystem. Hypothesis: Changing the elements of the environment within the bottle ecosystem will affect how the plants grow. If worms/bugs are added to the bottle they will live there. Materials: * 2 Liter pop bottle * Scissors * Soil * Seeds (grass

3.3 Cycles of Matter Recycling in the Biosphere Unlike the one-way flow of energy‚ matter is recycled within and between ecosystems Elements‚ chemical compounds and other matter are passed from one organism to another and from one part of the biosphere to another through biochemical cycles It connects biological‚ geological and chemical aspects of the biosphere Matter can cycle through biosphere because biological system do not use up matter; they transform Uses same molecules again and again

The business cycle is unavoidable because‚ in part‚ it is the economical representation of a volatile element: human psychology. In the example above‚ consumers are predictable.

Introduction: The design project‚ time restraints forced the Chainless Challenge team to design and build their competition bicycles without acquiring a good understanding of the dynamic nature of the system. It usually includes the quality‚ cost‚ and performance of the existing technologies. It is desired that a human powered vehicle be designed that does not utilize a direct

The Carbon Cycle Poppy Matless Carbon is present in all living organisms. When organisms die‚ the carbon is recycled for future generations. 1. Carbon is released as CO2 via respiration and combustion 2. CO2 is absorbed by producers (grass‚ plants etc) 3. Animals feed off of the plant‚ passing on carbon throughout the food chain‚ losing some carbon as CO2 respiration. 4. When the animal dies‚ it is eaten by decomposers‚ and the carbon returns to the atmosphere 5. If decomposition

The Main Parts of the Water Cycle The main parts of the water cycle are evaporation‚ condensation‚ and precipitation. They go together in a circle/cycle called the water cycle. None of these parts can be missing. (Well‚ everything in the water cycle is needed.) Evaporation- Evaporation is when water turns into water vapor and flows up into the sky. You can’t see it because it’s now gas and gas is invisible. Evaporation usually happens on hot‚ rainy days because the sun’s energy

Little Too Many? Do you ever go out to eat some seafood and see the fish that is served? Have you ever thought about the abundance; how much fish there is? And have you ever thought about there being a shortage a fish; seems impossible‚ right? Because when we think of fish‚ we think of the millions or even billions of little or big swimming creatures in the huge ocean; how could there be a shortage? Overfishing is the answer. Overfishing is where we hunt fish faster than they can be replaced naturally;

where does the water cycle gets its energy from? the water cycle gets the energy from the sun. why do we need the water cycle? since 97% of the earth is covered by salt water we can not drink it. we can remove salt from water but it could be very expensive. how does water get into oceans? when clouds can’t hold any more water it comes as precipitation and lands in the ocean. what is the water cycle made up of? it is made up of six different traits. condensation‚infiltration‚runoff‚ evaporation‚ precipitation

Imagine one thousand years in the future. The majority of the human population has died out due to unsustainable methods of resource use. All this is in the ancient past‚ but still‚ one thing remains: plastic. As the waves roll upon the beach‚ they hold within their grasp plastic wrappers‚ containers‚ but most of all bags. They drift in the wind over America’s great prairies and are caught on rocks at the highest peaks. Animals are seen wrapped in plastic struggling to move and breathe while others
