Q.1	Using the information from the table, deduce the most likely observable consequence in a marine ecosystem. Consider the combined effects on the marine food chain and other species interactions. Pollutant Impact on Marine Species Oil Coats and suffocates marine birds Plastic Causes entanglement and ingestion isues in sea animals Heavy Metals Lead to biomagnification in marine food chains Nutrients Result in algal blooms and dead zones
	a) A decrease in marine bird populations due to suffocation		b) A reduction in sea animal entanglement and ingestion issues
	c) A significant drop in algal blooms and dead zones		d) An amplification of heavy metal concentration in top predators

Q.2	In a lush rainforest, there is a diverse ecosystem with various plant and animal species. The interactions among these organisms involve multiple feeding relationships. What term best describes this intricate network of interconnected food chains?
	a) A diagram showing the transfer of energy in a straight line from one organism to another.		b) A sequence of organisms in an ecosystem, representing the transfer of energy from producers to consumers.
	c) A network of interconnected food chains, showing the complex feeding relationships in an ecosystem.		d) A diagram illustrating the process of photosynthesis in plants.
