Chapter 38: Problem 13

Urban designers included wetlands and lagoons connected to a water treatment plant to a new subdivision of homes. The designers would have most likely applied which principle of conservation to their plans? a. ecosystem service b. biodiversity preservation c. habitat restoration d. chemical diversity

Short Answer

Expert verified
a. ecosystem service

Step by step solution

01

- Identify the key elements

The exercise mentions urban designers included wetlands and lagoons connected to a water treatment plant in a new subdivision of homes.
02

- Recall the definition of ecosystem services

Ecosystem services are benefits provided by ecosystems to humans, such as clean water, air, and fertile soil.
03

- Analyze other options

Consider the other principles: biodiversity preservation (maintaining species diversity), habitat restoration (repairing damaged ecosystems), and chemical diversity (variety of chemicals in an environment).
04

- Match the key elements to the principles

Wetlands and lagoons often provide services such as water purification, which directly relates to ecosystem services.
05

- Select the most appropriate principle

Given the provided benefits of wetlands and lagoons, the most appropriate principle applied by the designers is ecosystem service (option a).

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Wetlands
Wetlands are areas where water covers the soil or is present at or near the surface for varying periods of time, including during the growing season. Wetlands are incredibly important for providing ecosystem services. They act as natural water filters, trapping pollutants and sediments. They also help in flood control by absorbing excess water during heavy rains. Additionally, wetlands provide habitats for a variety of wildlife, fostering biodiversity. Examples of wetlands include marshes, swamps, and bogs.
Biodiversity
Biodiversity refers to the variety of life in all its forms, from genes and species to ecosystems. It's essential for the stability and health of ecosystems. High biodiversity increases an ecosystem's resilience, helping it withstand environmental stress and recover from disturbances. Wetlands are particularly rich in biodiversity due to the unique and varied conditions they provide. They are home to many species of plants, birds, fish, and insects. Maintaining biodiversity is crucial for ecosystem services, such as pollination, nutrient cycling, and natural pest control.
Habitat Restoration
Habitat restoration is the process of returning a natural environment to its original condition after it has been damaged or degraded. This can involve activities such as replanting native vegetation, removing invasive species, and restoring natural water flows. Wetlands specifically can benefit greatly from habitat restoration, which can reestablish their crucial ecosystem services. Restoring wetlands can improve water quality, reduce flooding risks, and increase biodiversity. Effective habitat restoration involves understanding the specific needs of an ecosystem and planning accordingly.
