"What organisms depend on seaweed as an energy source?"

Explanation:

Marine algae are plant-like organisms that grow in the ocean. Algae are the basis of food and the only form of food) for many aquatic organisms, and can also be used in human food, since it is rich in minerals, such as Calcium, Iron and Iodine, proteins, carbohydrates and vitamin A. In addition, algae are responsible for autotrophs, that is, they perform photosynthesis and are responsible for a large part of the oxygen present in the atmosphere and thus proving that we humans are dependent on this organism.

One way to study and define the importance of marine algae in an ecosystem is the organisms that depend on them as an energy source, that is, they feed solely or preferably on marine algae.

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
