Question

List three examples of ecosystem services provided by biological resources.

Short answer

Food production, climate regulation, and recreational opportunities.

Step-by-step solution

Identify Ecosystem Services

Ecosystem services are the benefits that humans receive from ecosystems. There are several categories of these services, including provisioning, regulating, cultural, and supporting services. Each category contributes differently to human well-being and the environment.

Example of Provisioning Service

Biological resources such as plants provide provisioning services, such as the production of food. For instance, crops and livestock directly provide us with food which is essential for human survival.

Example of Regulating Service

Forests and other biological resources offer regulating services, such as climate regulation and carbon sequestration. Trees absorb carbon dioxide, helping to reduce the impact of climate change.

Example of Cultural Service

Biological resources also offer cultural services, such as recreational opportunities and spiritual wellbeing. National parks and natural reserves are biological areas that provide a space for recreation and tourism.

Key concepts

Provisioning Services

Provisioning services are one of the vital categories of ecosystem services that directly provide goods for human consumption and use. These services primarily include everything that can be obtained directly from ecosystems, catering to basic human needs and societal functions. Food production is one of the most notable provisioning services. This encompasses both plant-based foods such as fruits, vegetables, and cereals, and animal-based sources including meat, dairy, and eggs. These biological resources are crucial for sustaining human life and ensuring nutritional needs are met.

In addition to food, provisioning services also include the supply of water, raw materials like timber and fibers, and medicinal resources. Here are some key examples:

• Raw Materials: Forests provide wood for construction and fuel. Fibers such as cotton and wool are used in textile production.
• Medicinal Resources: Many plants are sources of pharmaceuticals and natural remedies integral for healthcare development.
• Freshwater: Ecosystems like rivers and lakes supply freshwater essential for drinking, irrigation, and sanitation.

These services are the foundation of many economic activities, emphasizing the interdependence between human society and nature.

Regulating Services

Regulating services are the ecosystem benefits derived from the natural regulatory processes that maintain environmental balance. These processes are crucial for sustaining life on Earth by regulating climate, air quality, and disease, among other factors. Forests, wetlands, and oceans play significant roles in regulating services.

For example, forests are central to climate regulation. They absorb carbon dioxide, a greenhouse gas, from the atmosphere, thereby helping to mitigate climate change. This process, known as carbon sequestration, is essential for reducing the impacts of global warming. Additionally, wetlands filter pollutants and sediments from water, improving water quality. This natural filtration system is vital for preserving clean water habitats and drinking supplies.

A few notable regulating services include:

• Climate Regulation: By moderating atmospheric concentrations of greenhouse gases, ecosystems help maintain a stable climate.
• Pollination: Insects and birds facilitate the reproduction of plants, ensuring food crop production and biodiversity.
• Erosion Control: Vegetation stabilizes soil and reduces the risk of landslides and soil degradation.

Overall, these services highlight the vital role ecosystems play in maintaining environmental homeostasis.

Cultural Services

Cultural services refer to the non-material benefits people derive from ecosystems, which contribute to the development and cultural identity of societies. These services intimately connect to human experiences, emotions, and spiritual well-being, offering aesthetic enjoyment, inspiration, recreation, and educational opportunities.

Natural landscapes, such as national parks, beaches, and mountains, often serve as prime locations for recreation and tourism activities. These areas offer a space for activities like hiking, swimming, and bird-watching, facilitating both leisure and adventure. Moreover, ecosystems are often integral to cultural heritage and spiritual values. Indigenous communities, for instance, may hold certain areas like forests or rivers as sacred.

Key aspects of cultural services include:

• Recreation and Tourism: Attracting visitors worldwide, these activities support local economies and foster appreciation for natural environments.
• Aesthetic Appreciation: Natural beauty inspires art, photography, and literature, enriching human experience and creativity.
• Education and Research: Ecosystems serve as living laboratories, providing opportunities for scientific study and environmental education.

Cultural services emphasize the connection between humans and nature, highlighting the importance of preserving ecosystems for future generations.
