3. B. temperature variation
4. C. salt content
5. D. pH of water
Any change that might affect a link of the trophic web, will inevitably cause a cascade effect in the whole web. In the exposed example, the number of autotrophs is the biotic factor affecting consumers in an ocean ecosystem.
---------------------------------------------------------------------------------------------------
In oceanicand terrestrial ecosystems, organisms build nets of varying levels of interaction known as the trophic webs.
The trophic web is a relationship process between different organisms, through which occurs transference of energy. The ones placed at lower levels pass energy to the ones at the higher levels.
Organisms at eachlevel feed on the preceding one and become food for the next one.
As it is a web, all organisms are equilibrated until a change occurs. When the change affects any of the involved links, there can be a cascade effect on the web. A change in a link population size (increasing or decreasing) will affect the superior links and the immediately anterior link.
Also, when two or more species are competing for the same source of food, a change in any of the population sizes will affect the other ones.
In the exposed example, we need to say which of the options are BIOTIC factors that affect consumers.
Among the options, there are temperature variations, salt content, and pH of water. All of them are significant factors that influence oceanic life. However, they are ABIOTIC factors.
The remaining option is the number of autotrophs. This option is a BIOTIC factor and is also the first link of many trophic chains.
Any change that might occur in this link -increasing or decreasing these populations-, will affect the whole system, beginning with their consumers.

The right answer is A), number of autotrophs.
B. A woman walks in a straight line with the sun to her right at nine o'clock in the morning. Toward which pole does she walk?
C. A man walks in a straight line with the sun to his right at three o'clock in the afternoon. Toward which pole does he walk?
D. A line of longitude
Woman walks in a straight line towards the north pole. In the morning the sun is in the east.
At night the sun is in the west therefore the man is walking to the south pole.
Equator is the termed as the line of latitude.
A line of longitude is known as the vertical lines which are parallel to the prime meridian.
Answer:
Ozone is the layer (blanket) on the atmosphere that protects lives on earth, from the harmful incoming ultraviolet solar radiation. This are UV rays can damage the skins of humans. It is denoted by O₃ and is located at the stratosphere.
This ozone layer has been significantly affected due to the emission of green house gases. The use of chlorofluorocarbon (CFC), methane gas (CH₄) as well as emission of carbon and sulfur has depleted the ozone layer.
Scientists have studied and examined why this depletion is going on and have suggested many steps to avoid ozone depletion and are still trying to find out the best solution to stop this ozone depletion. The use of products that contains CFC and releases methane gas must be avoided.
The ozone depletion is observed to be maximum in Antarctica because the environment there is suitable for the events that leads top the depletion of the ozone layer.
Ozone is simply a molecule consisting of 3 oxygen atoms, which reacts strongly with other molecules. Ozone is created in the stratosphere when high energy uv radiation causes on O2 molecule to split. The free oxygen atoms collide and react with other O2 molecules to form O3.
Production is highest where the solar uv is the greatest eg near the tropics, but once created, the ozone is then circulated towards the poles by the atmosphere. The amount of ozone in the stratosphere can vary with location, season and even day to day climatic conditions.
The process of ozone creation is what makes the O3 in the atmosphere very effective at shielding the Earth from harmful uv radiation, which can cause many biological problems, such as skin cancer. However, due to its high reactivity, the uv found in the tropospher at ground level can aslo be dangerous as a toxic pollutant which is harmful to plants and lung tissue, and is a major cause of smog.
Answer:
Acid rain, smog, ocean acidification and global warming and the impact they have on air pollution is not directly related to the toxicity of the gases. Acid rain and ocean acidification occur when pollutant gases react in the environment to form acid. Smog impacts the environment by filtering out sunlight and leaving less available for plants to use. Global warming occurs because greenhouse gases cause earth to retain more of the heat it collects from the sun.
Explanation:
Acid rain, smog, ocean acidification and global warming are indirect result of air pollution because these factors are interconnected. Water contains gas like carbon dioxide, but too much carbon dioxide makes the water acidic. Water contains gas like carbon dioxide, but too much carbon dioxide makes the water acidic.
Answer:
At the Equator (0° of latitude), the North Star is on the horizon, making an angle of 0°. For any point between the Equator and the North Pole, latitude is obtained simply by measuring the altitude of Polaris: at 30°N the star is 30° above the horizon, at 63°N, it is 63° above the horizon, and so on.
The altitude of Polaris above the horizon at any location on the Earth nearly equals the latitude of that place. This is due to the use of celestial coordinates, an extension of Earth's latitude and longitude onto a celestial sphere, where Polaris is close to the north celestial pole.
To find the altitude of Polaris (the North Star) from your location, you can use your latitude on Earth to get an approximation. The altitude of Polaris above the horizon nearly equals the latitude of the observer. So, for instance, if you are in Washington, DC, which has the coordinates 38° N and 77° W, Polaris would be approximately 38° above the northern horizon.
It's important to note this is related to an imaginary extension of Earth's geography into the sky. Imagine the Earth's latitude and longitude lines expanding onto a celestial sphere, where Polaris is located near the celestial north pole. In this concept, a star's Declination is equivalent to Earth's latitude lines, measured from the celestial equator towards the north or south celestial poles. Polaris is almost +90º, close to the north celestial pole.
