Evgen [1.6K]

Answer:

The higher you go in the good chain the lower the population.

Explanation:

In the food web, there are only a few sharks since in the food chain they are higher. Just 10% energy is retained in the tissues once the energy is moved from one trophic level to another, and the leftover power is emitted as metabolic energy.

If an animal is high up the energy ladder, the individual has less resources; thus, a few of the highest predators are present in an ecosystem.

8 was dividedby some numberthen added to13.next this difference was multiplied by 2 which gave a product of 30 find the answer
Anna11 [10]
The answer is 4. 

8/x +13 = y        -------->  y * 2 = 30 

divide 2 on both sides so y = 15

8/x + 13 = 15 
      - 13     - 13 

8/x = 2 

x =4
