The correct answer is D. Establishment of marine protected areas.
Marine protected areas (MPAs) are established to conserve and manage marine ecosystems through the protection of associated species and their habitats. MPAs can help maintain ecological balance, preserve biodiversity, and promote sustainable use of marine resources.
The other options do not represent ecological management and conservation through biological association:
A. Construction of a dam for hydroelectric power can disrupt ecosystems and harm associated species.
B. Introduction of an invasive species for pest control can harm native species and ecosystems.
C. Clear-cutting of a forest for timber extraction can destroy habitats and disrupt ecological associations.
MPAs, on the other hand, work with natural biological associations to preserve and protect ecosystems.
That's true, then again, destruction and invasion mentioned in B isn't really conservation, is it? Better still, the question does seem rather ambigious.
Review this, the answer is clearly option B since it says BIOLOGICAL ASSOCIATION i.e living things. The only biological association here is the predator-prey relationship in option B
Peace ✌️
Greetings, The Myschool Team.
The correct answer is B(Introduction of an invasive species for pest control) and not D(Establishment of marine protected areas). The question explicitly references biological association. The establishment of marine protected areas is a conservation measure, but does not utilize or relate to biological association. However, introduction of the natural enemy of a pest to control it as described in option B perfectly matches the concept of biological association (predation to be precise) while still being in the context of ecological management (eradication of pests). Thus, the correct answer is B(Introduction of an invasive species for pest control) and not D (Establishment of marine protected areas). Thank you.
B is right biological association is btw pest and predators e.g indroducing cat to a farmland infested with rodents
The correct answer is:
D. Establishment of marine protected areas
This represents ecological management and conservation through a biological association because marine protected areas (MPAs) are designated regions in oceans or coastal areas where human activity is restricted to conserve biodiversity and allow ecosystems to thrive naturally. They often involve protecting interdependent marine species and habitats, thereby maintaining the biological associations critical for ecological balance.
