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.
