This would be primary succession. Primary succession is succession starting from bare rock. Succession may start with weathering of the rock to create small pockets of lose soil. Seeds of pioneer plants may be carried by the wind to fall into pockets of soil with sufficient moisture to allow germination. The growth of pioneer plants will further break up the bare rock, creating a deeper layer of soil. As the plants grow, dead leaves and roots enrich the soil with organic content. Small animals start to colonise the area, such as gophers, who further break up and enrich the soil. The plants change from pioneer plants to plants of a specific biome. Succession will continue in this fashion until until an equilibrium is achieved.
When a star is fusing iron in its core, it's still giving off insane amounts of energy. ... Iron cannot be fused into anything heavier because of the insane amounts of energy and force required to fuse iron atoms. The atomic structure of iron is very stable, more so than most other elements.

Answer:
2. synthesize its own food
Explanation:
Based on how they obtain their nutrition, living organisms has been classified to be either producers, consumers, or decomposers. Producers are organisms capable of synthesizing their own food using light (photosynthesis) or inorganic chemicals (chemosynthesis).
Consumers, on the other hand, cannot synthesize their own food and hence, rely on other organisms to obtain their energy source. Consumers feed on other organisms to obtain energy. In this question, a fruit fly is classified as a CONSUMER because it cannot synthesize its own food.
