Fossil fuels are commercially available as an energy source.
They are very easy to find. More and more extractions of fossil fuels is going on everyday. With advancement in science and technology, the refineries and extraction procedures have improved a lot. This makes their availability even better.
Fossil fuels are also easily combustible. Most combustion engines need to be powered with little amount of fuel to produce large amount of energy. Very large amounts of electricity can be generated from fossil fuels.
The question is incomplete as it does not have the attached figure and the options which are:
A.) The population of frogs will decrease because of increased predation by snakes.
B.) The population of storks will increase because of decreased competition with eagles.
C.) The population of gnats will decrease because of a decrease in the amount of grass available.
D.) The population of grass will decrease because of increased predation by rabbits.
E.) The population of snakes will increase because of decreased predation by eagles.
Answer:
Option-A and E
Explanation:
In the given question, a structure of a complex food web has been provided in which the organism present at the different trophic level are affected by different factors including-
1. The population of Eagles (top consumer) has decreased due to human activities. Since the number of eagles has declined therefore the number of organisms on which it feeds will increase (snakes in the given question) due to no predation.
2. The population of rabbits (primary consumer) has decreased due to a virus. Since the number of rabbits will decline therefore the snakes will now shift eat more frogs and therefore the number of frogs will decline.
Thus, the selected options are correct.
Answer:
Explanation:
The closed metal container will get distorted or compressed due to a combination of two reasons:
1.<em> contraction of the metal container as a result of a reduction in its temperature.</em>
2. <em>a reduction in the pressure inside the container caused by a sudden drop in the temperature of the water inside it. </em>
The tap water causes a reduction in the temperature of both the container and the water inside it. An increase in temperature causes metal to expand and a reduction in temperature causes it to contract. Also, water takes less space than steam. Therefore, a reduction in the temperature of the hot water causes a reduction in the pressure inside the container relative to the outside. This causes the metal container to be compressed.
