Answer

It changes ocean temperature across the Gulf.
B
It prevents waves from reaching the shore.
C
It coats organisms, harming their feeding and breathing.
D
It provides nutrients for plankton and small fish.

Explanation

Oil can spread over the water and coat marine animals, birds, and plants. This coating can interfere with feeding, movement, and breathing, directly harming organisms in the ecosystem. It does not prevent waves from reaching shore or provide useful nutrients.
