Two terrestrial ecosystems based on photosynthesis and chemolithosynthesis (hydrothermal vents) trap their energy from specific energy sources. Tidal squeezing has also been suggested. The type of energy sources define the character of the ecosystems observed. What other energy source can you identify that might drive other kinds of ecosystems elsewhere in the universe? Speculate on the type of organisms that might evolve based on that energy source.What would be the characteristics of the primary producers (the organisms that trap the energy)?
You are discussing the choice of the “oil-eating” bacteria that you will use to clean the affected area from the oil spill and your team wants to know whether the Kalba sea constitutes a natural habitat for these bacteria.
Formulate a hypothesis stating why or why not the Kalba sea area can be considered a natural habitat for such bacteria. Support your answer by discussing the role of evolution in contributing to the survival and thriving of “oil-eating” bacteria. Explain how and why these bacteria acquired these characteristics
The idea of the great chain of being, or scala naturae suggests that
O a. all non-living and living things on earth can be arranged naturally on a
branching tree
O b. the earth is very young, and newly created
c. new life forms appear periodicly through a process of spontaneous
generation
O d. all life forms can be arrayed along a linear progression of increasing
reasoning ability
O e. the natural world is made up of a set of unchanging essences that are
discretely different from one another
