Osurvive and advance, humans have used the natural resources in their environment for at least as long as recorded history. some of these are renewable, like the wood from a forest, and some natural resources are not renewable, like oil pumped out of the ground. this is because we can use the wood from the forest, and plant trees to replace what was taken. with oil, we cannot replace what we have used, so when it is gone, it is gone for good. what is another example of a resource that has a limited supply? a) air. b) soil. c) coal. d) the sun.

The answer is C) coal. This is because coal is a natural resource and is made over millions of years; coal is being burned faster than it can be made.

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.
