Answer: Tertiary consumers
A tertiary consumer in a food chain is an organism which is carnivorous in nature, which means it feeds upon other organism belonging to lower trophic level like secondary and primary consumers. In ocean foodchain the parrotfish feeds on marine plants which are producers and parrotfish is a primary consumer. This parrotfish is eaten up by big fish which is a secondary consumer. This big fish is feed up by shark. Therefore, shark belongs to tertiary consumers.
Photosynthesis is the process of creating or producing energy from sunlight. This is a unique process employed by plants and oxygenic bacteria like Cyanophyta or Cyanobacteria. It is the chlorophyll, the green pigment in plants, that is primarily responsible for this process.
On the other hand, respiration occurs in most other living beings. The body's respiratory system allows it to obtain oxygen from the surrounding air.
The difference is that plants need sunlight to photosynthesize while other living creatures do not need it for respiration.
Also, plants take in carbon dioxide and expel oxygen in photosynthesis. Meanwhile, other living creatures take in oxygen and expel carbon dioxide. Thus, establishing an important mutual relationship between the two processes.

Answer:
i think it would be A for wild fire, D for flood and E for Tsunami
Explanation: wild fire are one of the most common ways for a secondary succession that can bring change when the environment is disturbed or damaged. For instance, by allowing fast-growing plants to grow and provide a source of food and shelter for many animals to use and eventually draw them back into the ecosystem. Both flooding and tsunamis help push older organisms and other stuff from the environment to create for room for other plants and animals to come and keep the ecosystem healthy and ongoing.
i hope this can help you with your work mate!
