A researcher is studying reproduction in Taraxacum officinale, the dandelion. She decides to measure only soil temperature. You think her study is poorly-designed. Why?
dandelions are not affected by soil temperature
biotic factors probably play a large role in dandelion reproduction
it is hard to measure soil temperature accurately
soil temperature varies too much
Some farmers use manure on their crop fields. How does this help the plants?
protects them from intense sunlight
keeps insects from eating the crops
increases soil nitrogen and phosphorus levels
increases soil oxygen and carbon dioxide levels

Why is a food web a better description for energy flow in an ecosystem than a food chain?
Food webs have less organisms.
Food webs are not a better description of energy flow in an ecosystem, food chains are better.
Food webs give every possible interaction of predator/prey, while food chains only give 1 possible interaction of predator/prey.
Food webs do not occur in all ecosystems.

photosynthesis & respiration
coal formation & photosynthesis
fuel combustion & open burning
death & decay
Which part of the food web shown contains the least biomass?
rabbits
mice
green plants
foxes
