5. Which one of the following statements about the human impact on Earth's
ecology is CORRECT?
, Humans commandeer as much as 25 percent of all photosynthetic production
on land.
Agriculture has increased abundance and distribution of some species, while
decreasing abundance and distribution of other species.
Human activities produce more carbon dioxide than do volcanoes.
All of these statements about the human impact on Earth's ecology are correct.
More atmospheric nitrogen is converted to ammonia by humans than by the
rest of nature.: All of these statements about the human impact on Earth's ecology are correct.
6. Imagine that you are standing in a field and you see a group of butterflies. You
notice an individual that looks significantly different from the other butterflies
