Answers

the frogs are all about the same size, varying in color and pattern.

The frogs are approximately the same size, but they exhibit a range of colors and patterns.

What is genetic variation?

The size of the frogs being similar and varying in color and pattern may be due to genetic variation within the population. This means that the frogs have different genetic traits that determine their color and pattern, but they still share the same general body size due to the genetic makeup of the population.

It's also possible that environmental factors, such as diet or temperature, could play a role in color and pattern variation, but not necessarily in size variation. Additionally, if the frogs are from the same species, their overall body size would be expected to be relatively similar due to shared genetic traits that determine their basic body structure.

Rainbow smelt and yellow perch attempt to occupy the same area. The more aggressive smelt survive; the perch do not.

Limiting factor-

Explain-

A severe flood brings a lot of sediment and silt into Lake Winnipeg. The turbidity of the lake increases greatly.

Limiting factor-

Explain-

A drought decreases the water level in Lake Winnipeg. The carrying capacity of the lake decreases.

Limiting factor-

Explain-

Due to the introduction of rainbow smelt, Lake Winnipeg becomes crowded and some fish species do not survive.

Limiting factor-

Explain-

Since northern pike prey on yellow perch, an increase in the perch population causes an increase in the pike population.

Limiting factor-

9:Density Dependent

Rainbow smelt and yellow perch attempt to occupy the same area. The more aggressive smelt survives the perch does not, showing the density-dependent limiting factor and all other question is also a density-dependent limiting factor.

What is a density-dependent limiting factor?

The density-dependent limiting factor is defined as the factor that affects the growth and size of the population that varies with the population density, disease predation, and competition are the density-dependent limiting factor.

While a density-independent limiting factor is considered as any force that change the size of the population but does not affect the density of the population.

In the given question Rainbow smelt and yellow perch attempt to occupy the same area. The more aggressive smelt survives the perch not is an example of density-dependent limiting factor.

Therefore, examples in the given question show density-dependent limiting factors.
