NASA reignited our hopes of finding alien life when it announced the first direct evidence of liquid water on Mars. But before we start indulging in fantasies of space crabs and reptilian beings, we ought to remember that Mars is a frigid world with a thin atmosphere. And that raises an obvious question: What sorts of life forms could actually live there?
Any life on Mars today is almost certainly microbial, but beyond that, we can’t be sure of anything until we actually dig it up and study it. Still, we can make some educated guesses about the nature of Martian life, by taking a deep dive into some of the weirdest biology on planet
Answer:
C. Large amounts of electricity can be produced, withought contributing to air pollution.
Trust me
X^2 - 2x - 8 = 0
(x - 4)(x + 2) = 0
x = 4 or x = -2
The positive root is x = 4

In interspecies competition, two species use the same limited resource. Competition has a negative effect on both of the species (-/- interaction).
A species' niche is basically its ecological role, which is defined by the set of conditions, resources, and interactions it needs (or can make use of).
The competitive exclusion principle says that two species can't coexist if they occupy exactly the same niche (competing for identical resources).
Two species whose niches overlap may evolve by natural selection to have more distinct niches, resulting in resource partitioning.
