Question

part 2: making connections
directions: refer to the videos and lesson 2.04 to help you answer the questions. type your answers in the yellow boxes. use complete sentences.

1. select two ecosystem services forests provide and explain what makes each an ecosystem service.

2a. identify a sustainable tree harvesting method that could replace the slash - and - burn method.
2b. explain why the method you chose is better for the environment.

1. describe one carbon - sequestering method from the lesson that can reduce the impacts of deforestation.
2. explain how forest management works to preserve and protect forests.

Explanation:

1. Ecosystem services: Forests provide water - purification and carbon - sequestration. Water - purification is an ecosystem service as trees filter pollutants from water. Carbon - sequestration is one because trees absorb carbon dioxide during photosynthesis, mitigating climate change.

2a. Sustainable tree - harvesting method: Selective logging can replace slash - and - burn.
2b. Benefits of selective logging: Selective logging only removes some trees, leaving the rest of the forest ecosystem intact. This helps maintain biodiversity, soil stability, and water - holding capacity compared to slash - and - burn which clears large areas and causes soil degradation and loss of habitat.

1. Carbon - sequestering method: Planting new trees (reforestation) can sequester carbon. Newly planted trees absorb carbon dioxide as they grow, reducing the amount of this greenhouse gas in the atmosphere and offsetting the carbon released by deforestation.
2. Forest management: Forest management involves activities like controlled logging, reforestation, and protection from wildfires and pests. These activities ensure a balance between human needs for forest products and the long - term health and sustainability of the forest ecosystem.

Answer:

1. Water - purification: Trees filter pollutants from water. Carbon - sequestration: Trees absorb carbon dioxide during photosynthesis.

2a. Selective logging.
2b. Selective logging only removes some trees, maintaining biodiversity, soil stability, and water - holding capacity.

1. Planting new trees (reforestation) to absorb carbon dioxide.
2. Involves controlled logging, reforestation, and protection from wildfires and pests to balance human needs and forest health.
