Answer: a. algal bloom

Explanation:

The availability of food in the systems can tell the types and numbers of organisms in the systems by checking which types of organisms eat the food available as well as the quantity available to see the number of organisms.

Temperature and dissolved oxygen levels also play a huge part in determining the feasibility of organisms staying in the system. The availability of nutrients goes hand in hand with the availability of food in determining the organisms present.

Algal bloom is not a factor in determining the types and numbers of organisms found in a system because the conditions that caused this bloom might not be suitable for other organisms as well.

Which of the following is true about coastal breezes?
9966 [12]

Answer:

They can blow from one direction in the morning, and from the opposite direction in the evening, and they are caused from differences in temperature of the land and the ocean.

Explanation:

The coastal breezes are breezes that occur near the coastlines. The general rule for the direction of the wind implies here as well as in any other place in the world, the wind blows from an area with higher air pressure toward an area with lower air pressure. When it comes to the coastal regions, because they have two contrasting landscapes, the wind changes direction during the day.

The land and the water have different properties, with the land heating up much faster and cooling off much faster, while the water heats and cools off slowly. This leads to larger oscillations in the temperature on land and with it larger oscillations in air pressure, while the temperature oscillations in the water are small and with it, the air pressure has much lower oscillation. When the land heats up, the wind blows from the ocean toward land because the air pressure is higher above the water, but when the land is cooler, the wind blows from the land toward the ocean because the air pressure is higher above the land.
