2 setting aside matters of life and death for the moment, what do ecologists mean by \exceptionally diverse.\ and why might anyone care? a comparison among some familiar places illustrates how numbers of species increase toward the equator, culminating in unparalleled tropical richness. california reaches from death valleys floor to mount whitneys summit, spans parched salt flats to drenched redwood groves, and yet across ten degrees of latitude boasts only thirty - five species of snakes. almost twice that number occur in la selvas five square miles, as if a house full of serpents were packed into a thimble, and there are nearly four hundred species of birds, more than half as many as in the continental united states. tropical faunas encompass more lifestyles too, thanks to rampant adaptive diversification; most temperate bats feed on insects, for example, whereas some of their hothouse relatives specialize on fruit, nectar, fish, frogs, or birds.
what does the phrase adaptive diversification mean in the sentence?
1. the range of activities in animals who respond to differences in weather
2. the change in habits of animals who move to different areas of the world
3. the variation in behaviors of animals who belong to the same general group
4. the diversity of foods eaten by animals who inhabit the same part of the world
part b
which detail from the sentence best supports the correct answer from part a?
1. ropical faunas\
2. \more lifestyles\

Accepted Answer

# Brief Explanations:
In the passage, it contrasts the diets of temperate and tropical bats, showing how animals within the same general group (bats) have different behaviors due to adaptive diversification. This indicates that adaptive diversification refers to the variation in behaviors of animals who belong to the same general group. The phrase "more lifestyles" supports this as it shows the different ways of living that result from adaptive diversification.
# Answer:
Part A: 3. the variation in behaviors of animals who belong to the same general group
Part B: 2. "more lifestyles"
