Chapter 52, Problem 6

When climbing a mountain, we can observe transitions in biological communities that are analogous to the changes a. in biomes at different latitudes. b. in different depths in the ocean. c. in a community through different seasons. d. in an ecosystem as it evolves over time.

Step 1: Understand the question. The question is asking about the changes in biological communities that we can observe when climbing a mountain. These changes are analogous to some other type of change in nature.
Step 2: Review each of the options and consider how they relate to changes in biological communities. Option a suggests that the changes are similar to those in biomes at different latitudes. Option b suggests a similarity to changes in different depths in the ocean. Option c suggests a similarity to changes in a community through different seasons. Option d suggests a similarity to changes in an ecosystem as it evolves over time.
Step 3: Consider the nature of changes when climbing a mountain. As we ascend, the temperature and pressure decrease, and the types of plants and animals we encounter change. This is similar to moving from the equator towards the poles, where temperature and pressure also decrease and the types of organisms change.
Step 4: Compare this to the other options. Changes in ocean depth are more about pressure and light levels than temperature. Changes through seasons are cyclical and reversible, unlike a mountain climb. Changes in an ecosystem over time (ecological succession) are about the ecosystem's development and maturation, not a steady change in conditions like temperature or pressure.
Step 5: Conclude that the changes in biological communities when climbing a mountain are most analogous to the changes in biomes at different latitudes (option a), as both involve a steady change in conditions like temperature and pressure, leading to different types of organisms being present.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Biomes and Latitude

Biomes are large ecological areas characterized by specific climate conditions, flora, and fauna. They vary with latitude, as temperature and precipitation patterns change from the equator to the poles. Understanding how biomes shift with latitude helps explain the diversity of life forms and adaptations found in different regions.

Ecological Succession

Ecological succession is the process by which ecosystems change and develop over time, often following a disturbance. It involves a series of stages where different communities of organisms replace one another, leading to a stable climax community. This concept is crucial for understanding how biological communities evolve in response to environmental changes.

Vertical Zonation in Aquatic Ecosystems

Vertical zonation refers to the distinct ecological zones that occur at different depths in aquatic environments, such as oceans and lakes. Each zone has unique physical and biological characteristics, influencing the types of organisms that can thrive there. This concept is important for recognizing how depth affects biodiversity and community structure in aquatic ecosystems.
