Food is the only limiting factor that keeps populations from growing too large true or false?

Answers

The correct answer is False

Explanation:

A limiting factor refers to a condition that stops or limits the growth of a population of any species. Some of these factors include the availability of sources such as food, shelter or water; predation; natural weather conditions; natural disasters; and competence.

The previous idea implies food is not the only factor or condition that would stop or limit the growth of a population but there are many other factors that could prevent a population from growing too large, this includes abiotic factors (nonliving condition) such as weather and biotic factors (living condition) such as competition with other species or individuals or predation.

Food is not the only limiting factor that keeps populations from growing too large. This statement is false.

Populations are regulated by a variety of factors, including but not limited to food availability. These factors can be categorized into two main types: density-dependent and density-independent factors.

Density-dependent factors are influenced by population size and include factors such as competition for resources (including food), predation, disease, and territoriality.

As a population grows, competition for limited resources, including food, increases. This can lead to reduced growth, increased mortality, and ultimately limit the population's size.

Thus, while food availability is an important factor in population dynamics, it is not the sole limiting factor. Other ecological factors and interactions within the ecosystem play significant roles in regulating population size and preventing populations from growing too large.

Which of the following currents is associated with downslope movements of dense sediment-rich water? (1 point) avalanche current density current turbidity current longshore current

Answers

The current that is associated with downslope movements of dense sediment-rich water is called turbidity current. 

Answer : Option C) Turbidity Current

Explanation :

The current that is associated downslope movements of dense sediment-rich water is turbidity current.

A turbidity current is most typically termed when an underwater current of usually rapidly moving, which has high sediment-laden water which is movies down a slope.

Turbidity currents is mostly caused by earthquakes, or collapsing slopes, or any other geological disturbances.

Which of the following types of mixtures exhibit the Tyndall effect?a. solutions
c. colloids
b. suspensions
d. none of the above

Answers

C) Colloids

Colloids have small non-dissolved particles that flow around in the mixture. These particles do not settle over time. When a light is shined on colloids the scattering characteristic of the Tyndall effect are visable.

A chunk of silver has a heat capacity if 42.8 j/*c. If the silver has a mass of 181g, calculate the specific heat of sliver.

Answers

From the given question, we know
Heat capacity of the chunk of silver = 42.8 J/c
Mass of the silver = 181 g
Now we also know the formula for determining the specific heat of silver and that is
Specific heat (C) = heat capacity/ mass
                             = (42.8/181) J/gC
                             = 0.24 J/gC
So the specific heat of the silver is 0.24 J/gC.
With the given known facts, it is easily possible to find out the specific gravity of any substance.
