Answer:

The correct answer is - decreased population size at all levels.

Explanation:

A decrease in the productivity of producers of an ecosystem will lead to a decrease in all other organisms of the ecosystem including top-level consumers to the bottom-level producers due to the fact that producers provide energy and food to primary consumers.

It is because they are the only organisms that convert the sunlight to usable energy and food that transfer from one trophic level to other, so if the population of producers or their productivity will decrease then there will be decreased population size at all levels.

How would you write this number in scientific notation? (Use the carrot key to denote an exponent. ex: 6.02 x 10^23)
NeTakaya

Answer:

D=5.89\times 10^{12}\ km

Explanation:

The distance to the Sun is 5,890,000,000,000. We need to write this distance in km.

A number can be written as x.0\times 10^y in scientific notation where x is a real no and y is any integer.

There are 10 zeros in the given number and also there are 12 digits after. It would mean that,

D=5.89\times 10^{12}\ km

So, the distance in scientific notation is : D=5.89\times 10^{12}\ km
