whoever answers this I will give the brainiest! Consider limiting factors in aquatic ecosystems. a. Describe three reasons why sunlight is a limiting factor in aquatic ecosystem. (/3) b. Describe the importance of nitrogen and calcium in an aquatic ecosystem. (/2)

Explanation:

1)Sunlight is a limiting factor because it helps the plants grow.

2) plants and trees give u oxygen so that u can breathe

3) plants and trees are habitats for some animals.

Increased nitrogen can increase the growth of algae which is a benefit of it

their crystal patterns have been disrupted by stress

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
