Imagine walking through a tropical rainforest. You notice that there are different
types of trees, birds, insects, and other organisms. A few weeks later you are taking a
walk through the desert and notice that the trees, birds, insects, and other organisms
are different than those you saw in the rainforest. Which of the following statements
best explains the differences between each of these ecological systems?
Organisms in each ecological system are there by chance and their presence in
different ecological systems does not have a biological explanation.
Organisms in each ecological system have short dispersal distances and are
confined to populations in the area where they mate.
Organisms in each ecological system have not had enough time to evolve the
adaptations for the other ecosystem; with enough time they will evolve into the
other ecological system.
Organisms in each ecological system have not had enough time to evolve the

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
Most biologists and climatologists agree that the earth is warming, why do people disregard the evidence for global warming? What should be done to reach the public?

- How are abiotic factors important in the process of natural selection? The abiotic factors of an environment include nonliving things that affect where the organism lives. The conditions or environment where an organism lives is the base for an organism making adaptations. If they are well adapted, they will survive; if not, they will not survive. The abiotic factors are the plants that live in the ecosystem. If the organism can feed off the plants, it will survive. If it cannot find a food source, it will not survive. The abiotic factors are the species within the ecosystem that compete for resources. The organisms that are able to obtain these factors will survive; those that are not will not survive. The abiotic factors are the number of predators present in the ecosystem where the organism lives. If the organism can fend off the predator, it will survive.arrow_forwardThe ecosystem concept revolutionized ecology by introducing holistic systems thinking as opposed to individualistic life history studies. Why was this a conceptual breakthrough?arrow_forwardTopic: Galapagos Finches Darwin’s readings took him to a predictive theory of how species might change with time: what later thinkers have called microevolution. Darwin’s philosophical worldview then took him beyond his evidence to a conviction that environmental constraints could create whole new structures and organisms. Soon Darwin’s theory of macroevolution replaced the Creator with an environment that could create solely by constraint. For your thread: According to Chapter 13 section 13.1, define microevolution and macroevolution. The Galapagos islands have a great diversity of landscapes – from lush vegetation to nearly barren lava fields yet the Galapagos Finches survive on each island. How can this be explained? Using the varying bills of the Galapagos Finches in figure 13.3 and additional research, explain how microevolution is evidenced.arrow_forward

Why do pesticides lose their effectiveness over time? Use the theory of natural selection and evolution to explain.arrow_forward
- Evidence from Biogeography Biogeography is the study of how and why plants and animals live where they do. It provides more evidence for evolution. Let's consider the camel family as an example. Biogeography of Camels: An Example Today, the camel family includes different types of camels. All of today's camels are descended from the same camel ancestors. These ancestors lived in North America about a million years ago. Early North American camels migrated to other places. Some went to East Asia. They crossed a land bridge during the last ice age. A few of them made it all the way to Africa. Others went to South America. They crossed the Isthmus of Panama. Once camels reached these different places, they evolved independently. They evolved adaptations that suited them for the particular environment where they lived. Through natural selection, descendants of the original camel ancestors evolved the diversity they have today.

This, in turn, stimulates the formation of possible explanations, termed hypotheses, that can be tested by collecting data from a study or an experiment.
