Different areas on a mountain receive different levels of sunlight and temperatures throughout the year. As you go further north or south on the planet, you will experience the same thing. The temperatures won’t stay the same. A is the lowest, B the hottest, C the middle, D the warmest and E the lowest.
This is a very simple model, but it has a lot of interesting implications. For example, if you look at a map of the Earth‘s surface, there are a number of places where the temperature is very different from the average temperature on Earth. These are places like the Arctic, the Antarctic, and the Sahara desert. In these places, it’s very cold and very hot.
If you were to go to one of these locations and stand in the sun for a long period of time, your skin would start to burn and you would get very sick. This is why it is so important to understand how the climate is changing and how we can adapt to it.

Which of the following environmental conditions poses presents the strongest physiological challenge for a fish swimming into an estuary from a river?
The osmotic balance in the fish‘s body would be challenged by the change in water solute content. (a) The fish is exposed to a high concentration of dissolved solutes (e.g., nitrate, nitrite, and/or ammonia) in its environment. (b) There is a rapid increase in salinity (i.e., the water becomes more acidic). (c) In addition to the above conditions, there are other environmental factors, such as the presence of other fish species, that may also pose a challenge to fish in estuaries.
Which of the following biomes would you find the greatest number of bird species?
More than 200 species of bird are found nowhere else in western and central Africa, according to the International Union for the Preservation of Nature’s Red List of Threatened Species.
Where would you expect to find the littoral zone of a lake?
The nearshore area of the lake is the warmest part of the lake and allows sunlight to penetrate all the way to the bottom of the lake. The zone is most affected by the amount of sunlight that reaches the surface and the water temperature.
In the summer, when the water is warm and the sun is high in the sky, water temperatures in this zone can reach as high as 50°C (122°F). In the winter, the temperature drops to as low as -20° C (-4° F) and can drop below freezing in some areas.
The lake‘s surface is covered with a layer of ice, which can be as thin as 1 cm (0.4 inches) or as thick as 10 cm (.6 inches). The ice is made up of a variety of minerals, including calcium carbonate (CaCO 3 ), magnesium oxide (MgO), and silica (SiO 2 ).
In addition, there are large amounts of dissolved salts, such as sodium chloride (NaCl), chloride and bicarbonate of soda (H 2 CO 3 ).
Which of the following environmental conditions is most likely to be a stressor for plants?
When the water supply to the roots is limited, or when the transpiration rate is too high, it can be a sign that there is a problem. The two conditions coincide with the start of the dry season. In the case of plants, the stress can be caused by a number of factors, such as the amount of water available in the soil, temperature, moisture content, and other factors.
However, it is important to keep in mind that there are many factors that can affect the response of a plant to a drought. For example, some plants are more sensitive to drought than others. In addition, plants respond differently to different types of stressors. Some plants may be more susceptible to heat stress, while others may not be affected as much by cold stress and may even be able to cope with both heat and cold at the same time.
It is also important not to assume that a particular plant is more or less likely to respond to stress than another plant. Plants respond in a variety of ways to various environmental conditions, including drought, heat, cold, salinity, nutrient availability, etc. Therefore, there is no single “one size fits all” approach to dealing with a given situation.
Which lake zone would be absent in a very shallow pond or lake?
The aphotic zone is not present in a very shallow lake. Aphotic is a Greek word meaning without and aphos meaning flower. Aphotic zones are usually found in shallow lakes and rivers. They can be found along the banks of rivers, lakes, streams, ponds, creeks, swamps, marshes and other shallow bodies of water. In some cases, they can also occur in the open ocean, but this is rare.
Which of the biomes is maintained by fire?
There are grass lands. Fires are good in a grassland because it is a “fire-maintained” environment. Habitat for a wide variety of plant and animal species is provided by it. The grasslands of the United States are the largest and most diverse in the world.
They cover an area larger than the state of New York and are home to more than 1,000 species of plants and animals. Grasslands are also the most productive ecosystems on the planet, with an average annual yield of 1.5 billion tons of carbon dioxide equivalent (CO2e) per hectare.
In addition to providing habitat and food for wildlife and humans, they also play an important role in regulating the climate by regulating evapotranspiration, which is the process by which water evaporates from the surface of a land surface and is absorbed into the atmosphere.
This process, known as the “greenhouse effect,” is responsible for keeping the Earth‘s surface temperature from rising too much, thereby keeping us from overheating and causing global warming.
How can you identify a littoral zone?
The amount of dissolved organic matter in the water column and the amount of sunlight can be used to define the littoral zone. DOC is a by-product of photosynthesis, which is the process by which plants use sunlight to convert carbon dioxide (CO 2 ) into sugars and oxygen (O 2 ).
It is important for the health of aquatic ecosystems because it provides a source of nutrients for fish and other aquatic organisms. However, DOC is also a pollutant that can accumulate in sediments and in surface waters, where it can interfere with the ability of organisms to photosynthesize and grow.
In addition, the accumulation of DOC can lead to the formation of phytoplankton blooms (PBLs), which can have a negative impact on the quality of surface water and on fish populations. These effects are particularly pronounced in areas where DOC concentrations are high, such as the Gulf of Mexico and Great Lakes, as well as in coastal areas of the U.S. and Canada.
Which organism would you expect to find at the littoral zone?
The littoral zone includes part of the shore, the intertidal zone, and some of the shallow parts of the body of water. The littoral zone is home to many species, examples include crabs, sea urchins, lobsters, clams, mussels, snails, worms, mollusks, crustaceans, fish, birds, mammals, reptiles, invertebrates, etc. The ocean is the largest ocean in the world.
It is home to more than 100,000 species of marine life, including whales, dolphins, porpoises, seals, seabirds, sharks, rays, turtles, octopuses, squid and many others. The ocean also contains a large amount of fresh water, which is used by humans for drinking, cooking, washing, bathing and other purposes.
What would you expect to find in the profundal zone of a lake?
The Profundal Zone is a cold water region below the euphotic zone. The lack of oxygen in the water causes the profundal zone to have lower fish populations. The Benthic Zone is the final zone. The fish are most likely to be found at the bottom of a cold pond or lake.
In the diagram below, you can see the different zones and how they relate to each other. You can also see that there are many different types of fish that live in each zone.
Which of the following is the cause of generalized global air circulation and precipitation patterns?
There is differential heating. The global atmospheric circulation caused by the rotation of our planet is the reason we have different weather patterns. The Earth‘s atmosphere is made up of three main layers: the troposphere, the stratosphere and the thermosphere. Tropospheric is the lowest layer, which is where the air is at its most dense. Thermospheres are the second and third layers of atmosphere.
These layers are responsible for convection, or the movement of warm and cold air masses around the Earth. In addition to these three layers, there is also a fourth layer called the mesosphere. This layer is much thinner than the other three, and it is located at the very edge of space.
It is composed mostly of nitrogen and oxygen, but it also contains trace amounts of carbon dioxide, methane, water vapor, carbon monoxide, hydrogen sulfide, sulfur dioxide and nitrogen oxides.
