Is the Clapper Raid headed for extinction or is the species having a temporary decline due to excessive predation, lack of resources, a disruption in the lower tropic levels, or some other reason? Explain your response as it relates to the specific ecosystem.
2.) If nature had previously recycled nutrients using forest fires as the mechanism, why must we use "prescribed burns" to accomplish the same results today?
3.) What are the similarities and differences between the function of the decomposers and the effects of periodic fires?
4.) Can energy be recycled?
5.) Why do ecological pyramids have a wide base and a narrow tip?
6.) What are some of the methods used to study weather patterns? Do you think the data collected can help to predict future climatic conditions?
7.) Are temperature gradients present in all biomes? What is one example of an adaptation to a colder temperature range?
8.) Can you also give an example of adaptation to a very arid environment?

Find the angle of depression
: A weather satellite is traveling in a circular orbit 9800 miles above the surface of the earth. Find the angle of depression from the television satellite to the horizon. Assume that the radius of the earth is 4000 miles.

State a titanium rod of length and circular diameter
: A titanium rod of length 10 cm and circular diameter of 2 cm is pulled in tension with a load of 100000 N. The rod elongates by 0.01 cm under the load but recovers to its original length when the load is released.

Estimate the maximum possible error
: The radius of a circular disk is given as 30 cm with a maximum error in measurement of 04 cm. Use differentials to estimate the maximum possible error in the calculated area of the disk.

Find the terminal point
: find the terminal point p(x,y) on the unit circle determined by the given value of t.

Compute the transformation rate the austenite-to-pearlite
: Calculate the transformation rate for the austenite-to-pearlite transformation at 650 °C and at 600 °C. Show the relationship(s) you used to arrive at your answers.

How does mutualism differ from commensalism
: What do the J- and S-shaped population curves indicate about the life span of an organism and does competitive exclusion limit the diversity within a given community?

At what angle is the bat
: A baseball player is up at bat. With the bat angled 60deg clockwise of forward and rotating clockwise at 160deg/sec, the player begins to accelerate the bat counterclockwise at a constant 2300deg/s^2(squared). The ball arrives at the plate 300ms l..
