Question

A major threat to ocean life comes from

• A. Disposal of sewage
• B. oil spillage due to tanker accidents
• C. Acid rains
• D. Garbage disposal by ships

Answer 1

The correct option is B

oil spillage due to tanker accidents

Spilled oil can harm living things because its chemical constituents are poisonous. This can affect organisms both from internal exposure to oil through ingestion or inhalation and from external exposure through skin and eye irritation. Oil can also smother some small species of fish or invertebrates and coat feathers and fur, reducing the ability of birds and mammals to maintain their body temperatures.
