<h3>What is perspectives?</h3>
  • Many other perspectives help frame a distinctly geographic way of looking at the world, in addition to the two primary geographic perspectives, spatial and ecological.
  • When applied correctly, these additional perspectives broaden our understanding of spatial patterns and human-environment interaction.
  • Social geography focuses on societal divisions, initially class, ethnicity, and, to a lesser extent, religion; however, other factors, such as gender, sexual orientation, and age, have recently been added.
  • Geographic perspective allows us to consider the environmental, economic, political, and/or social implications of the issues, events, developments, and/or phenomena with which we live.
  • Recognize the natural and built environments, as well as the processes that shape and affect the earth.

Several key factors help to determine the types and numbers of organisms found in the various layers of both freshwater and mari
bearhunter [10]

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.
