A.) It is estimated that the mature Atlantic herring population today has a bio-mass (total weight of the population) of approximately 2 million metric tonnes (2 billion kg). If an average adult Atlantic herring weighs 0.125 kg, how many adult Atlantic herring are there in the entire population? Hint: kg /0.125 kg per fish = fish
There are fish in the entire population.

B.) An adult Atlantic herring consumes, on average, 10 g of plankton per day. How much plankton would the adult Atlantic herring population consume in a day?
The population would consume grams of plankton a day.

C.) If there were a severe reduction of plankton available to the Atlantic herring population, and therefore a 55% decrease in the herring, how many mature Atlantic herring would be supported by the ecosystem?
The ecosystem could support fish.

D.) How many kilograms would that equate to?
It would be kilograms.

Explanation:

im gonna compare the cells to jobs in factory. give brainliest

job in the factory //       cell organelle   //  

shipping/receiving

department                 plasma membrane    

chief executive officer// nucleus

factory floor // cytoplasm

assembly line// endoplasmic reticulum

workers in the assembly line //ribosomes

finishing/packaging department //golgi apparatus

maintenance crew //lysosomes

support beams (walls, ceilings, floors) //cytoskeleton

power plant //mitochondria/chloroplasts

here's what each part of the cell does:

plasma membrane :

regulates what enters and leaves the cell; where cell makes contact with the external environment

nucleus :

controls all cell activity; determines what proteins will be made

cytoplasm :

contains the organelles; site of most cell activity

endoplasmic reticulum:

where ribosomes do their work

ribosomes :

build the proteins

golgi apparatus :

prepares proteins for use or export

lysosomes :

responsible for breaking down and absorbing materials taken in by the cell

cytoskeleton :

maintains cell shape

mitochondria/chloroplasts :

transforms one form of energy into another
