Final answer:
The presence of brown kelp in the Indian Ocean can have both positive and negative effects on the ecosystem. Brown kelp provides habitat and food for marine organisms, but excessive growth can lead to negative impacts such as blocking sunlight and oxygen depletion.
Step-by-step explanation:
The presence of brown kelp in the Indian Ocean can have both positive and negative effects on the ecosystem in that location. Brown kelp, also known as seaweeds, are a type of brown algae that play an important role in marine ecosystems. They provide habitat and shelter for various marine organisms and serve as a food source for herbivorous animals.
However, if the brown kelp grows out of proportion and forms dense mats, it can have negative impacts on the ecosystem. These dense mats can block sunlight from reaching other underwater plants, potentially causing their death. In addition, the decomposition of excess brown kelp can lead to oxygen depletion in the water, harming other organisms.
Overall, the presence of brown kelp in the Indian Ocean can have both positive and negative effects on the ecosystem, depending on its abundance and distribution.
