As the question is incomplete and there are no statements available based on which the question can be answered. But based on the knowledge it can be answered.
Answer:
Most of the corals contains photosynthetic algae which are known as zooxanthllae which lives in the tissues of the corals. Algae and corals have mutualistic relationship.
The corals provide algae space to live and algae provides coral food such as glucose and glycerols to them which are considered as products of photosynthesis.
If the producers are hampered by the catastrophic event then the main source of the food will be hampered. There will be less or no food source for the corals which covers a large area in the marine ecosystem.
There are chances that there will be more load on the other photosynthetic organism in water as there will be more population dependent on them for food.
Hence, if there is a loss of habitat for these protist other levels of food chain will be affected due to inter connection.
Answer: As a plant begins to grow, an embryonic root emerges from the seed, termed the radicle or primary root. This allows the seedling to become anchored in the ground and begin absorbing water and nutrients. No matter how a seed is planted, the root will orient itself towards the pull of gravity in the downward direction.

Prokaryotes have circular DNA
<span>The texture of the rock is a great example of the environment for igneous rocks. Many rocks of this type tend to have very jagged or rough textures, and are shown to come from environments that are high in heat, pressure, and also change greatly over short periods of time due to the many eruptions and lava flows that take place.</span>
