Question

biodiversity
notes
definition:
the total variety of all living organisms/species,
genetic, ecosystem diversity in a given area.

• high biodiversity means...

an ecosystem with many different species,
complex food webs, & high resilience to disturbance.

• low biodiversity means...

an ecosystem with very few species, simple food
webs, & low resilience.

• draw three ways that humans benefit from biodiverse ecosystems.

Explanation:

1. Provisioning Benefits: Biodiverse ecosystems supply humans with essential resources like food (crop varieties, wild game), medicinal plants, raw materials (timber, fibers), and clean water, supporting basic survival and economic activity.
2. Regulating Benefits: They provide critical ecosystem services that regulate environmental conditions, such as pollination of crops by diverse insect species, water purification by wetland organisms, carbon sequestration by forests to mitigate climate change, and pest control by natural predators.
3. Cultural & Recreational Benefits: Biodiverse areas offer cultural value (spiritual or traditional significance for many communities), recreational opportunities (hiking, birdwatching, ecotourism), and support scientific research to advance medical and ecological knowledge.

Answer:

1. Access to diverse food, medicine, and raw materials (provisioning services)
2. Natural regulation of climate, pollination, and water quality (regulating services)
3. Cultural, recreational, and scientific research opportunities (cultural services)
