What are some common sampling techniques used to investigate the distribution and abundance of organisms in a habitat?
What are some common sampling techniques used to investigate the distribution and abundance of organisms in a habitat?
Common sampling techniques include random sampling, transects, and capture-recapture methods.
Describe one positive and one negative human interaction within ecosystems.
Describe one positive and one negative human interaction within ecosystems.
A positive interaction is conservation efforts aimed at protecting endangered species, while a negative interaction is deforestation, which threatens biodiversity.
Explain a benefit and a challenge of maintaining biodiversity at a global scale.
Explain a benefit and a challenge of maintaining biodiversity at a global scale.
A benefit of maintaining biodiversity is enhanced ecosystem services, while a challenge includes the difficulty in securing international agreements for conservation.

Study Notes
Learning Outcomes for B6.1
-
B6.1a: Field investigations into organism distribution and abundance. Includes sampling techniques (random, transects, capture-recapture), quadrat use, pooters, nets, and scaling methods for accurate population counts.
-
B6.1b: Positive and negative human interactions within ecosystems and their biodiversity impact. Explores the conservation of individual species and habitats, along with threats from human activity (e.g., land use, hunting).
-
B6.1c: Benefits and challenges of maintaining local and global biodiversity. Addresses the importance, difficulties, and value of diverse ecosystems.
-
B6.1d: Environmental change impacts on organisms. Focuses on the evidence for these, particularly concerning the distribution of organisms and the impact of water and atmospheric gases.
