Environmental Science question: chain reactions linking acorns to moth outbreaks and lyme disease risk? - lyme disease and black toes
I have read a passage and then answer a few questions on this topic. Here is the passage:
The oak trees produce large crops of acorns fall every 2-5 years and produce few or no acorns in the intervening years. The acorns are important food for white-footed mice. The mice are the main predators of the gypsy moth pupation. This insect has suffered periodic outbreaks that defoliate millions of hectares of oak, the tree growth, survival and production of acorn crops reduced. The abundance of acorns, food for white-tailed deer. Mice and deer are the main hosts of the black-legged tick, Lyme disease causes.
: QUESTIONS
1.) Schematic representation of a food chain based on relationships of the organisms identified in the extract.
2.) Design a controlled experiment that tests the relationship between acorn production and the gypsy moth population. Add the hypothesis that the experimental results.
thank you soo much!

Lyme Disease And Black Toes Environmental Science Question: Chain Reactions Linking Acorns To Moth Outbreaks And Lyme Disease Risk?

Damn good question. Will it force the question.
A couple of things. For the food chain, you write the names of places in the Post-it small and put them on a piece of paper that you display the energy flows from one to another. If you have problems, consult the references to another piece of paper and re-start. If it looks good, make a copy of "clean" hand
For the experiment, start with a hypothesis. Then look at historical data, which correlation between the factors. Note that there will be a time lag involved. For example, mice impair reproductive gypsy moth in the next generation, not the current one. Followed by a prediction about the future cycles a year or so the line tested.
