Wild crickets living in a field have a population density of 2 4 crickets m2 if the fields area is 250m2 what is the aproximite size of the cricket population why would the population density of?

Answer 1

TANK 1

With 200 crickets occupying an area of 0.80 square meters, that gives a population density of

. . 200 crickets

-------------------------- = ? crickets / square meter

0.80 square meters

Is that amount < or = or > the maximum of 210 crickets / square meter?.

= = = = = = = = = = = = = = = = = = = = = = = = =

TANK 2

With 150 crickets occupying an area of 0.80 square meters, that gives a population density of

. . 150 crickets

--------------------------- = ? crickets / square meter

0.80 square meters

Is that amount < or = or > the maximum of 210 crickets / square meter?.

= = = = = = = = = = = = = = = = = = = = = = = = =

TANK 3

With 315 crickets occupying an area of 1.5 square meters, that gives a population density of

. . 315 crickets

------------------------- = ? crickets / square meter

1.5 square meters

Is that amount < or = or > the maximum of 210 crickets / square meter?.

= = = = = = = = = = = = = = = = = = = = = = =

For PROBLEM #1, when you move crickets from tank to tank, remember to change the value of the numerators in the fractions above.

EXAMPLE

If you remove 10 crickets from tank 2 and put them in tank 3, then decrease tank 2's numerator from 150 to 140 and increase tank 3's numerator from 315 to 325.

For PROBLEM #2, we need to rearrange the formula from above

(number of crickets)

-------------------------- = population density

. . . . (area)

Multiply both sides of the equal sign by (area).

(area)(number of crickets)

----------------------------------- = (area)(population density)

. . . . . . . (area)

Notice how the (area) on the left side cancels out?

(number of crickets) = (area)(population density)

(number of crickets) = (250 square meters)(2.4 crickets / square meter)

(number of crickets) = ?

Answer 2

The approximate size of the cricket population in the field would be 600 crickets. To calculate this, multiply the population density (24 crickets/m^2) by the area of the field in square meters (250 m^2). Population density can be influenced by factors such as availability of food, predation, habitat quality, and competition for resources.
