The shark population will change eventually because the more sharks the more food they need to eat and if the sharks are increasing there eating all the clams and shellfish. The data shows that recently the shark population increased. How will the increase in the shark population affect the other populations? Be sure to explain whether the sea otter population, the sea star population, and the clam population will change, and why?
(pls add a nice long explanation without any hard words, and whoever answers first will get a brainliest, thanks, and a 5 star review!!!) Pls hurry! I am counting on ya'll!

Answers

Answer:

Increase in sharks, decrease in otters, increase in clams, increase in sea stars.

Explanation:

As the shark population increases, they will prey on more otters. The otters consume clams, which means with fewer otters the clams will be able to increase. The sea stars will have more clams to prey on, so they will also increase.

The increase in sharks population will have an effect on the population of sea otters, sea star and clam. All these three animals depend on the diet on which the sharks eat. More sharks then more food will be eaten and less food for these three animals. So when there is less food to eat many of these three animal population dies and soon the food chain will fall apart. For example, less population of river otter, crocodiles won’t have much food to eat. As you can see increase in shark population can sort of break the food chain.

1.complete the explanation to Sherman.
Well, no Sherman, mutation does not work like that, here’s how it really works.

2.If there had been a mutation that led to no fur, what would have happened?
A. The trait would have been adaptive
B.the trait would have been non-adaptive
C. the trait would have become more common over time
D the trait would have become less common over time

Where there is a gene mutation, it will be observed that the trait would have become less common over time.

What is mutation?

Mutation refers to a change in the gene sequence of an organism that leads to the emergence of an new trait or the disappearance of an existing trait.

What would the mean values be? (the green boxes)

Answers

Answer:

First Mean = 5

Second Mean = 3

Third Mean = 6

Fourth Mean = 9

Explanation:

For each column you just add up the data numbers and divide them by how many numbers is in that column which would be 3.

0.5 + 14.0 + 0.5 = 15 | 15 / 3 = 5

2.5 + 4.0 + 2.5 = 9 | 9 / 3 = 3

6.0 + 7.0 + 5.0 = 18 | 18 / 3 = 6

8.0 + 10.0 + 9.0 = 27 | 27 / 3 = 9

First= 5
Second= 3
Third= 6
Fourth= 9

3. Decomposers are organisms that obtain energy by breaking down dead matter and recycling the nutrients back into the soil. Decomposers are often left out of food chains and food webs. However, they are essential to life on Earth. What would happen if there were no decomposers?

Answers

Answer:

(based of what I would think )

Explanation:

If we didn't have decomposers, the waste left from the food we eat and what the wolves and stuff eat would grow into a problem, we would have ( i think) a mess or something

( more people can answer this better then me)

If decomposers are not there then:-

The dead leaves, insects and other organisms would pile up everywhere.Vital nutrients that are available in ecosystem will not be there.There will be no recycling of matter between biotic and abiotic components of an ecosystem.

What are decomposer?These are various organisms that return constituents of organic substances to ecological substance to ecological cycles by feeding on them.These include Yeast, Molds, Mushrooms.

Explain why food chains, food web, and energy pyramids typically do not have more than four levels of consumer?

Answers

The reason food chains, food webs, and energy pyramids do not typically have more than four trophic levels is because the energy and biomass decrease when you are going up to the higher levels.
