Answer:
B) limiting factors
Explanation:
Phytoplankton, also known as microalgae, are similar to land-based plants in that they contain chlorophyll and require sunlight in order to live and grow. Most phytoplankton are buoyant and float in the upper part of the ocean, where sunlight penetrates the water. Phytoplankton also require inorganic nutrients such as nitrates, phosphates, and sulfur which they convert into proteins, fats, and carbohydrates.
In a balanced ecosystem, phytoplankton provide food for a wide range of sea creatures including krill, shrimp, snails, and jellyfish, that are in turn food for larger animals like sea turtles, fish and whales. However, under certain environmental conditions, such as the introduction of too many nutrients from land based sources of pollution, phytoplankton may grow out of control and form blooms.
These blooms can be problematic because the excess algae can block out sunlight, which is bad for plants like seagrasses that need sunlight to make food. Zooxanthallae, or symbiotic algae that live in the tissue of coral and supply coral with food, can also be impacted by algal blooms. Excess algae can also smother other critters living on the ocean floor.
The factors such as sunlight, nutrient, and water to survive all cinditions that for algae bloom which are called: B. limiting factors.
Limiting factors can be defined as those constrains that slows or stop the growth of a population. They may include food, biotic factors, or even competetion from other organisms in the environment for limited available resources.
Thus, factors such as sunlight, nutrient, and water to survive all cinditions that for algae bloom which are called: B. limiting factors.
