1. What is the main source of energy for ecosystems?

2. What are some natural things that can disturb ecosystems?

Answers

Answer:

1.Photosynthesis is the process of converting light into energy

2.Natural events, such as wind, drought, flood, fire, or disease.

Explanation:

1.Since photosynthesis converts light into C-H bonds in organic material, photosynthesis is the most common source of energy in most habitats, and therefore carbon flow and destiny are inextricably related to energy flow.

2.Natural disasters such as wind, drought, storm, burning, or disease may cause disruption. These "natural occurrences" are often linked to human activities. Air and water emissions, as well as climate change effects such as temperature, rainfall, and ocean chemistry, are also examples of human disruptions.

Answer:

If the wind constantly pushes a rock, eventually the sides will start eroding, and the wind will cause it to break and erode.

Resources affect populations
Living and nonliving things are both found within the same ecosystem. The living things require the non living things for survival.

Limiting Factors
Environmental factors, such as the amount of water, food, sunlight and temperature available, are limiting factors for a population.

A limiting factor is sometimes that restricts the size of a population. Limiting factors might affect the number of individuals in the ecosystem can support.

The amount of space affects a population’s size.

Available water, food, sunlight and temperature are all limiting factors.

Space is also a limiting factor.

If there are too few resources, populations may migrate to new areas.

Answer:

- The amount of space affects a population's size.

- Available water, food, sunlight and temperature are limiting factors

- Space is also a limiting factor.

The following table shows the distance from the sun of some unknown planets of equal mass.

W 1.5 AU
X 0.723 AU

Which of the following best explains which planet revolves at a faster speed?
A.) Planet X, because the sun pulls it with a greater force.
B.) Planet W, because the sun pulls it with a greater force.
C.) Planet W, because the gravitational force is weakened by distance.
D.) Planet X, because the gravitational force is strengthened by distance.

Answers

I think that the correct answer is A

Answer:

Option D.) Planet X, because the gravitational force is strengthened by distance.

Explanation:

As we know from Kepler's law , the planets that are closer to the sun move at a faster rate in comparison to those planets that are far because of high gravitational force.

According to the question,

both planets have equal mass. Plant W is at 1.5 AU and planet X is at 0.723 AU distance from the sun.

So, planet X revolves at a faster speed because it's shorter distance from the sum as comparison to planet W, strengthened the gravitational field.

Thus, Option D is the correct answer.

Disease can reduce the size of a population quickly.

The amount of resources, such as food and water, limit how many pikas can survive.

The presence of predators limits how large the population can grow.

As the population grows, the pikas compete with each other for resources.

The amount and types of space avalible in an environment mean only a certain number of pikas can make homes.

Answers

#4: An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts

#5: It is not surprising that human population density is a leading cause of species invasions. Species are easily moved by human and animal (particularly domestic animal) vectors, and increasing populations residing next to protected areas simply means increasing the odds of species introduction
