Not all adults feed at a high trophic level. Whale sharks (50 ft) are the largest fish and feed on plankton and small fish, while Great White sharks (20 ft) are the largest carnivorous fish and feed on sea lions, seals and large fish. Blue whales (100 ft) are the largest whale and feed primarily on plankton and krill, while the Sperm whale (45 ft) is the largest carnivorous whale feeding on fish and very large squid.
(a) How does the location of each animal's position in relation to the producers contribute to their size? Be sure to look at the food chain and the amount of energy that is being transferred between the levels.
(b) Why do you suppose the plankton feeders are able to attain such large sizes compared to the carnivores?

Here are 3 interlocking gears. The largest gear has 14 teeth, the middle gear has 12 teeth, and the smallest gear has 6 teeth. The smallest gear can ONLY move in a counterclockwise direction, while the middle gear can move counter clockwise.


Q: How many turns will each gear have to make in order to turn all gears in their original starting direction??

Certain facts about space are widely accepted:

1) It is REALLY big... many claim infinite. This means there are near infinite chances for the right life supporting conditions to occur on at least one other planet.
2) That humankind could neither visit nor observe 99.9999% of it even if we could travel at light speed. As such if life already existed we probably wouldn't know about it.
3) That scattered throughout space there are millions of solar systems like ours. Each planet with its unique climatic characteristics.
4) Space based life forms (even earth based ones) do not have to be carbon based. Silicon or Sulphur would work too.
5) Finally the majority of the world's population claims to believe in some god. If people believe in a larger creator how would life on other planets seem so impossible?
