The given diagram represents an ecological pyramid showing the trophic levels in an ecosystem. Which of the following statements is correct regarding the energy flow in this pyramid?
| 1. | Energy increases progressively from producers to top carnivores due to biomagnification. |
| 2. | Herbivores occupy the first trophic level and are primary producers. |
| 3. | The energy available to each successive trophic level decreases due to loss in the form of heat and metabolism. |
| 4. | Top carnivores receive the highest amount of energy from the producers. |

In most ecosystems, biomass pyramids are upright, but in the ocean, the pyramid of biomass is inverted. Why does this occur?
| 1. | Phytoplankton have low biomass but high productivity, allowing rapid energy transfer to higher trophic levels. |
| 2. | The biomass of zooplankton and fish is constantly decreasing, leading to an imbalance. |
| 3. | Oceanic consumers do not depend on phytoplankton for their energy needs. |
| 4. | Marine ecosystems function differently, where energy transfer is highly inefficient. |
