Scientists calculated the net primary productivity at two different forest sites. Both forests have the same gross primary productivity. Forest A has a net primary productivity of 1,650 kcal/m2/year , and forest B has a net primary productivity of 1,110 kcal/m2/year . Which of the following statements is best supported by the data? 1. Forest A has a higher rate of decomposition by bacteria than forest B.
2. Forest A has more biodiversity than forest B.
3. Forest A producers have lower rates of cellular respiration than forest B producers.
4. Forest A producers have more biomass than forest B producers.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
