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.

1) D because even if you rip all them out, the seeds of the plant are still in the ground
2) D because of the current, short-legged birds might get swept away
3) D because all of the other options would most likely not enforced.
<span> A. Insects (living) carry seeds (living)to new places, which allow new plants to grow.
B. People(living) plant trees(living) in a city park.
C. A drought dries up a river(not living), so deer(living) have less water to drink.
D. A fungus(living) causes a grove of trees(living) to die.
The answer is C because river is the only not living(abiotic) factor in these case</span>
The products of cellular respiration are carbon dioxide and water. Carbon dioxide is transported from your mitochondria out of your cell, to your red blood cells, and back to your lungs to be exhaled. ATP is generated in the process
<u>Biological augmentation</u>
Using nitrogen-fixing soybean crops to add nitrogen to degraded soils is an example of <u>Biological augmentation.</u>

<h3>What is biological augmentation?</h3>
- The process of accelerating the breakdown of a pollutant through the addition of archaea or bacterial cultures is known as biological augmentation.
- It's possible that organisms from contaminated locations can already break down garbage, but possibly slowly and inefficiently.
<h3>What is an example of biological enhancement?</h3>
- Systems that use biofiltration are frequently employed to remove toxins from soil or groundwater.
- Treatment ponds, slow sand filters, and bioswales are a few types of biofilters.
<h3>What purpose does biological enhancement serve?</h3>
- The best part of this addition is that it is natural and enhances the quality, clarity, and reduction of organic sediments (muck) that build up over time on the bottom of a body of water.
- Clean-Flo is a pioneer in the stimulation of native microorganisms in addition to the addition of microbes.
