A network of interactions that involves the cycling of materials and the flow of energy among organisms and their
physical environment is ____. a. a population b. a community c. an ecosystem d. the biosphere e. the habitat
Researchers applied radioactive phosphorus and radioactive calcium to a freshly cut tree stump. Eight days later, they came back to measure the distribution of the radioisotopes. They found that nineteen different species of shrubs and trees within a seven-meter radius had taken up the radioactive elements. No radioactivity was detected in the air. Radioactive isotopes were never detected in any samples containing just soil taken during the experiment. The finding implies that the
a. soil does not provide the ecosystem with minerals b. isotopes were undetectable in very small amounts c. isotopes were transported via vascular tissues d. plants quickly return minerals to the soil in which they grow e. soil speeds up radioactive decay
