Examples are lakes and ponds.
What is Standing Water?
100
Species disappears for all or part of its range.
What is Extinction?
100
You would expect to find this in a plant cell and not a animal cell (and it is not the cell wall).
What is Chloroplast?
200
Can view images 1000x smaller than a light microscope.
What is a Electron Microscope?
200
Photosynthesis, respiration, and decompostion.
What are Biological Processes?
200
Is an ecosytem in which water either covers teh soil or is present at or near the surgace of the soil for at least part of the year.
What is Freshwater Wetlands?
200
Development splits ecosytems in half, creating small "islands" of habbitat.
What is Habitat Framentation?
200
Specialized structures in the cell that perform important cellular functions.
What is an Organelle?
