Question

plants and animals
diverse crops
high biodiversity
ecosystem services and biodiversity:

1. what are four examples of ecosystem services?
2. describe in detail one of the ecosystem services? (use one of the examples provided on slides 44 & 45)

measuring and preserving biodiversity:

1. what is one strategy in biodiversity conservation?

Explanation:

1. Ecosystem services are benefits that humans obtain from ecosystems. Four common examples are provisioning services (like food and water supply), regulating services (such as climate - regulation and flood control), cultural services (including recreation and aesthetic enjoyment), and supporting services (like nutrient cycling and soil formation).
2. For example, climate - regulation is a regulating service. Ecosystems like forests absorb carbon dioxide through photosynthesis, which helps mitigate the greenhouse effect and regulate the Earth's climate. Trees store carbon in their biomass and soil, reducing the amount of this potent greenhouse gas in the atmosphere.
3. One strategy in biodiversity conservation is the establishment of protected areas. These areas, such as national parks and nature reserves, set aside land or water to protect species and their habitats from human - induced threats like deforestation, over - hunting, and pollution.

Answer:

1. Provisioning services, regulating services, cultural services, supporting services.
2. Climate - regulation: Forests absorb carbon dioxide through photosynthesis, store carbon in biomass and soil, reducing greenhouse gas levels in the atmosphere.
3. Establishment of protected areas.
