Question

1. true or false: a marine food web represents a linear path of energy flow among organisms in marine ecosystems.
2. true or false: primary consumers are herbivores that feed on primary producers.
3. true or false: decomposers play a crucial role in capturing solar energy in marine ecosystems.
4. true or false: overfishing can lead to an increase in the population of secondary consumers.
5. true or false: the primary producers in marine food webs are mostly phytoplankton and algae.
6. true or false: tertiary consumers are the base of the marine food web.
7. true or false: climate change can result in coral bleaching, negatively affecting marine food webs.
8. true or false: cod are considered apex predators in the north sea ecosystem.
9. true or false: pollutants can accumulate in the tissues of marine organisms, affecting higher trophic levels.
10. true or false: the interactions between producers, consumers, and decomposers are essential for nutrient cycling in marine ecosystems.

Explanation:

1. A marine food - web is a complex network, not a linear path.
2. Primary consumers are herbivores that feed on primary producers.
3. Decomposers break down dead matter, not capture solar energy.
4. Overfishing can disrupt the food - web and usually decreases secondary consumers' populations.
5. Primary producers like phytoplankton and algae are the base of the marine food web.
6. Tertiary consumers are at the top, not the base.
7. Climate change can cause coral bleaching.
8. Cod are not apex predators in the North Sea ecosystem.
9. Pollutants can bioaccumulate in marine organisms.
10. Interactions between producers, consumers, and decomposers are crucial for nutrient cycling.
