Preview Questions Marine Biologist | Role Specific Skill

Question 1: In terms of climate change impacts, what is the primary effect on marine food webs?

Which action should you take?

Choose only one option

A decrease in ocean temperature enhancing species growth

Introduction of new species to improve ecosystem function

Alteration of species distribution and changes in food availability

A rise in primary production leading to an increase in biomass

Question 2: How does marine restoration differ from marine conservation, and what role does it play in preserving ocean biodiversity?

Which action should you take?

Choose only one option

Restoration focuses on managing marine fisheries

Restoration focuses on protecting species, while conservation manages habitats

Restoration is primarily focused on preventing human interaction with marine environments

Restoration focuses on rebuilding ecosystems while conservation preserves them

Question 3: What is the role of the ocean's biological pump in carbon sequestration?

Which action should you take?

Choose only one option
