This document contains a test bank with multiple choice and essay questions about ecology. It begins with 20 multiple choice questions about ecological concepts like ecological hierarchies, populations, communities, ecosystems, evolution, and thermodynamics. These are followed by several short answer questions requiring explanations about how different ecological levels interact and influence each other. The questions assess understanding of core ecological principles and how they relate to real world examples like pesticide use and resource depletion.

1. The document discusses atomic evolution, which is the process by which simple atoms evolve into more complex atoms through fusion of nuclei. It also discusses how increased complexity in systems and organisms leads to decreased stability based on the Principles of Complexity and Instability.
2. It then covers basic concepts about cell structure, genes, and mutations. Differentiation of function is defined as the development of specialized structures in multicellular organisms that allow for functions to help the total organism survive.
3. Sexual reproduction is discussed as providing advantages over asexual reproduction, including allowing for variation within a species and avoiding some instability from mutation.

BIO Module 6 Overview
Ecosystems and Ecology
This module will continue the examination of fundamental concepts related to ecology. It will introduce the complex phenomena of interactions between organisms and their habitats, as well as the delicate interactions between communities of organisms. It will explain why changing one part of a community can lead to unexpected consequences. This module will also examine the concept of populations and their growth curves. This material is relevant to the question of a population's "carrying capacity," and, in turn, the Malthusian theory of overpopulation. Finally, you will delve into the fascinating issues surrounding instinctive and learned behavior among animals.

9A
Describe the flow of atoms through the carbon, nitrogen, phosphorus, and hydrologic cycles.
9B
Identify biotic and abiotic environmental factors.

9J
Explain why people in poor countries eat mostly plant material.
9K
Differentiate among predation, mutualism, competition, parasitism, and commensalism.

18. How might one hierarchical level that is not in steady state affect the hierarchical level above it?
ANSWER: If the individual level is not maintained in steady state, this might mean that the
organism would not find enough food to meet its energy requirements, reducing its
fitness. If continued across multiple individuals, the birth rate might decrease and
the death rate increase, leading to the potential for the population to go out of
equilibrium as well.

20. How might the use of pesticides to control insects that feed on wheat affect how the insects evolve?
ANSWER: If some insects survive the initial application, they may be resistant to the chemical
as a result of their genetic makeup. The surviving insects could pass on that trait to
the next generation. Over time, the insect species may evolve to be resistant to the
pesticide.

ANSWER: If two species have the identical niche, they will be competing for the same
resources in the same place during the same time. While both species might
survive for a brief period, eventually the better competitor will outcompete the
other species, leading to the elimination of the lesser competitor from the
community.

34. Plants and animals exchange energy and materials with their physical environments. These exchanges occur
across surfaces. In animals, surfaces tend to be internal, while in plants, surfaces tend to be external. Discuss the
principal reason for this important difference.
ANSWER: Animals obtain energy from foods they consume. This absorption is best
accomplished internally, where foods can be subjected to conditions that release
molecules to be taken up across large areas of absorptive structures. Most plants
obtain energy from sunlight. They must expose relatively large external absorptive
surfaces (typically leaves) to sunlight to obtain this energy, which makes internal
absorption impractical.

ANSWER: The small size of most protists makes it easy for them to live inside other larger

specialized adaptations that can be very useful to other organisms. An example of

45. A scientist hypothesizes that the larvae of a particular species of swallowtail butterfly uses olfaction (the
sense of smell) to locate their preferred host plants in the carrot family. To test the hypothesis, the scientist uses
extracts from various plants—including some from the carrot family—to moisten small pieces of paper
arranged randomly under a wire screen. Swallowtail larvae are released on the wire screen but cannot come into
direct physical contact with the pieces of paper. What is the advantage of this experiment compared to simply
presenting the larvae with a choice among various plants?
ANSWER: The scientist wants to vary the volatile chemicals presented to the larvae without
giving the larvae other cues to the identity of the plants from which these
chemicals are extracted. Since all of the pieces of paper look alike, the scientist can
eliminate the possibility that the larvae use visual cues to recognize the pieces of
paper moistened with extracts from plants in the carrot family. Separating the
larvae from the pieces of paper ensures that the larvae cannot use their sense of
taste.

b. Sea otters catch and eat trash fish, allowing stocks of commercially valuable fish to increase.
c. Sea otters catch and eat sea urchins, thereby protecting kelps, which in turn shelter populations of
larval fish.
d. Sea otters have been used in medical research to develop vaccines that protect domestic cats from a
variety of diseases.

56. Use the example of the California sea otter to explain why ecologists must study multiple hierarchical levels
to understand most environmental problems.
ANSWER: One part of the sea otter story that illustrates this is the population loss due to killer
whales. The food preferences of the whales had to be understood (on the individual
level), but so did the community and ecosystem interactions between lower seal
and sea lion populations due to low fish populations, which drove killer whales to
find new food sources.

63. Explain why two competitive species would have greater similarity in their respective niche than two
species in which one is a predator and the other the prey (of that predator).
ANSWER: Two competitive species would not only be found in the same habitat and likely
feeding at the same time, but would also be feeding at the same trophic level and
likely on the same species.

64. The interactions known as herbivory and predation are considered to both result in a +/- outcome between
the two species involved in each of the interactions (one species benefits; the other species is harmed). How are
these two interactions different?
ANSWER: Predation tends to be lethal to the species negatively impacted, while in herbivory
the interaction is not lethal to the species negatively impacted.

65. Explain, in terms of fitness and natural selection, why a species should have adapted to avoid competition.
ANSWER: Competition has a negative impact on both species’ fitness. Energy is spent
competing for resources that might have been allocated for reproduction
(improving one’s fitness by producing more offspring) if adapted (behaviorally or
morphologically) to avoid competition.

66. Explain the difference between organisms identified as decomposers and those identified as detritivores.
ANSWER: Decomposers are typically fungi and bacteria and function by breaking down
biological material into elements and compounds that can be reused in the system.
Detritivores tend to be invertebrates that feed off of dead organic material as their
food source, breaking the material down into smaller parts that facilitate the action
of decomposers by increasing the surface area for bacteria and fungi to act.
