2L3 Quiz Energy and Matter in Ecosystems

Quiz on ecosystem energy & matter cycles: carbon, nitrogen, water. Understand energy conservation!

1. The law of conservation of energystates that energy cannot be created or destroyed.2. Matterhas mass and takes up space.3. The open systemrefers to matter that can enter from or escape to the surroundings.4. Evaporationis when water changes from liquid to vapor (gas).5. Transpirationis when plants release water vapor from their leaves.6. The rain, snow, hail, or sleet are examples of precipitation.7. The nitrogen cycle transfers nitrogen from the atmosphere to the soil, to living organisms, and back to the atmosphere. The diagram shows part of the carbon cycle. What's happening in step 1? Animals are decomposing and releasing carbon into the soil. Animals are releasing energy into the environment and storing carbon. Animals are converting carbon dioxide from the atmosphere to oxygen. Animals are breaking down organic molecules and releasing carbon dioxide into the atmosphere. A scientist is studying a substance that is cycled through ecosystems. Which of the following substances might the scientist be studying? soil copper glucose nitrogen What is energy? the ability to do work anything that has mass anything that takes up space the ability to conduct current Where does the majority of evaporation onEarth occur? between streams and ponds between the oceans and the atmosphere between the ground and the atmosphere between Earth’s surface and underground aquifers Which phrase best describes a consumer in an ecosystem? an organism that is at the bottom of the food chain an organism that breaks down dead plants and animals an organism that gets its energy by eating plants or animals an organism that converts light energy into chemical energy Match the correct definition Groundwater water held underground in the soil or in pores and crevices in rock. Runoff Water that moves across the land surface and into streams and rivers Respiration breathing; organisms release water as waste nitrogen fixation Process of converting nitrogen gas into usable nitrogen Combustion the process of burning something carbon cycle The organic circulation of carbon from the atmosphere into organisms and back again Condensation The change of state from a gas(vapor) to a liquid
