According to the Law of Conservation of Energy, energy is neither created nor destroyed. Technically, it is impossible for the plant to produce energy twice this input. It could only be possible if an external energy is required to create a reaction that would create more energy. This external energy could in the form of energy or another chemical containing potential energy.
Mechanical advantage is the answer.
Option B.
<h3><u>Explanation:</u></h3>
A machine is defined as the instrument which is used to perform some task easily, and with ease. A machine has the capability to give an output force in exchange of an input force. Now the ratio of the output force to input force is called as the mechanical advantage.
Mechanical advantage = Output force / input force.
For example, in case of a lever, there are three types - first class lever, second class lever, and third class lever. Mechanical advantage for a second class lever is always more than one, as we get more output force than input force. Similarly, the mechanical advantage for a third class lever is always less than 1, and mechanical advantage of first class lever can be both more or less or equal to one.
There are two types of succession that lead to the increasment of the ecosystem:
1. Primary succession is the change in the structure of an ecosystem represented with the increase of the ecological community on an area that has not been previously occupied by an ecological community such as area after the lava flow or glacial lake. The first organisms of primary succession are pioneer plants usually, lichens and mosses.
2. Secondary succession includes the step of removal of pre-existing community and after that, colonization of the new one.
Answer:
the correct answer would be D
Explanation:
How did the sunflowers depict their rivalry in the image? Why should they fight it out?
The reason I've chosen this as a scientific topic is because the area is covered in sunflowers. With the conditions of their surroundings, living organisms attempt to live. As a result, there is rivalry among the organisms.
