How does an oil spill affect the primary producers in an ecosystem?

An oil spill significantly impacts primary producers, such as phytoplankton and aquatic plants, by coating their surfaces with oil, which obstructs sunlight penetration and disrupts photosynthesis. The toxic components of the oil can also harm these organisms directly, leading to reduced growth and reproductive rates. Additionally, the contamination of their habitat can result in long-term ecological shifts, affecting the entire food web and reducing overall biodiversity in the ecosystem.
