Explain how fluctuations in abiotic cycles can influence populations

2 answers:

8 0

The fluctuations in abiotic cycles can influence the population in many ways. The population of a particular area depends on the various abiotic cycles such as nitrogen cycle, carbon cycle, phosphorous cycle. The changes in these cycles affects the life of population. Fluctuation results in hibernation of species. Some of the organisms migrate to another place in search of normal environment. The early breeding results in creating problems. It disturbs the ecological balance by using the limited supply of resources. The fluctuation in phosphorous cycle can affect the aquatic population. As the dependency of population on abiotic cycles is as important as the biotic factors the fluctuations can cause many problem.

Populations are influenced by fluctuations in any of the abiotic cycles. The fluctuations of seasonal cycles can cause populations to hibernate, migrate, or breed. Organisms breed as a result of seasonal fluctucations that cause them to have a limited resource supply. Fluctuations in the phosphorus cycle can cause changes to aquatic ecosystems, either positive or negative.

Explain what happens during the process of photosynthesis

Lynna [10]

Oxygen is made and so is glucose (its actually sugar, but glucose is better sounding) by combining carbon dioxide and water using light energy as a source of energy. Also like to make sugars.

Describe the molecules in a solid. How is that different than molecules in gas?

Lostsunrise [7]

Answer:

The molecules in a solid are more closely packed than those in a gas. Gas molecules are VERY spread apart, which is why we cannot see them.

The phenotype of an organism is its physical characteristics, which result from the organsism's genes.

FromTheMoon [43]

What is the question ??

The term "phenotype" refers to the observable physical properties of an organism; these include the organism's appearance, development, and behavior. An organism's phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.

An object has a weight of 21,532 N on Earth. What is the mass of the object?

Nuetrik [128]

7) 2,197 kg

The weight of an object on Earth is given by:

$W=mg$

where m is the mass of the object and $g=9.8 m/s^2$ is the acceleration due to gravity. Since we know the weight of the object, W=21,532 N, we can re-arrange the equation to calculate the object's mass:

$m=\frac{W}{g}=\frac{21,532 N}{9.8 m/s^2}=2,197 kg$

8) 2,197 kg

Mass is an intrinsec property of an object: it says "how much matter" is contained within an object. Therefore, the mass of an object does not depend on its location: so, the object has the same mass on Earth and on the moon, and so its mass is still the same as the previous exercise, 2,197 kg.

9) 187,500 N

The force exerted on an object is given by Newton's second law:

$F=ma$

where m is the mass of the object and a its acceleration. In this problem, $m=250 kg$ and $a=750 m/s^2$ , so the force exerted on the object is

$F=(250 kg)(750 m/s^2)=187,500 N$

10) 2nd Law

Newton's second law states that an object which is acted upon a force experiences an acceleration given by:

$a=\frac{F}{m}$

where F is the force and m the mass of the object. As a result, the object accelerates, so if it was at rest, it starts moving.

This is exactly what happens in this example: the ball is initially at rest, but then a force is applied on it (by the kick), so the ball is accelerated and it starts moving.
