Ch.3 Ecosystem Dynamics

2. precipitation that seeps into the soil and collects in an aquifer.
3. cycle that collects, purifies, and distributes earths fixed supply of water.
4. complex process that uses oxygen and glucose to produce energy and occurs in the cells of most living organisms.
6. consumer organism that feeds on detritus-fleshy dead organisms.
9. a animal that mostly feeds on other animals.
11. cyclic movement of nitrogen in different chemical forms from the environment to organisms and then back to the environment.
12. sequence of organisms in which each organism is a source of nutrients or energy for the next level of organisms.
14. form of cellular respiration in which some decomposers get the energy that need through the breakdown of glucose.

1. consumer that feeds on both primary and secondary consumers.
5. precipitation that falls on land and flows over the land surfaces into streams, rivers, lakes, wetlands, and the ocean, where it can evaporate and repeat the hydrologic cycle.
7. animal that can use both plants and animals for a food source.
8. complex network of interconnected food chains.
10. porous, water-saturated layers of sand, gravel, or bedrock in which groundwater collects.
13. consumers that get their nutrients by breaking down nonliving matters such as leaf litter, fallen trees, ect.
