Answer:
A: light availability
B: nutrients
Explanation:
Both nutrients and light availability affect the primary productivity of the freshwater ecosystem, therefore, scientists study both factors to track associated changes. This is because photosynthesis is driven by sunlight and nutrients availability. It is suggested that the abundance of autotrophs (e.g. phytoplanktons) in an aquatic ecosystem increases as light and nutrients availability increase. Thus, there will be more food available for secondary and tertiary consumers to feed upon. Resultantly, the aquatic environment will turn a biodiversity hotspot where many species of living organisms start dwelling. Thus, scientists mainly ecologists would focus on these two parameters at first that lead to consideration of other parameters.

d. scientific theory
Explanation:
The statement that all living things like planktons are made up of cells is a true scientific theory.
All living organisms are made up of cells and all cells are derived from pre-existing cells is the first and most fundamental postulate of the cell theory.
- the concept that living things are made up of cell is from the cell theory.
- the cell is the fundamental unit of life.
- the cell theory provides an explanation into cells as the unit of life

Answer:
Mass is conserved in living systems through the processes of photosynthesis, cellular respiration, and the carbon cycle. It is demonstrated in cellular respiration through the process of braking down food to provide energy and releasing carbon dioxide.
