Answer:
Scenario I, Scenario II, and Scenario III are examples of competitive networks.
Explanation:
There are different examples of nets as interactions between species. Trophic net is a very common example of these interactions. Another one is the competitive network.
The competitive network refers to the competition for the same resource between different species in a community or ecosystem. When a resource is useful for two or more species, they compete to gain it.
The competitive network can be represented as arrows that indicate which is the dominant species over the other. This representation must be done with a<u> minimum of two species interacting</u> and indicating through the direction of the arrow, which species wins the competition.
There is a competitive hierarchy when there are more than two species, for example, species A, B, and C. Species A dominates over the other two, and species B dominates over species C. In these cases, the representation would be A --> B --> C. This reflects a transitive competitive network. Species A displaces species B and C, and species B displaces species C. The only species that can persist is A. This example can be extended to <u>any number of species</u>, which suggests that a hierarchy network does not promote biologic diversity.

The Sidereal Day is 4 minutes shorter than the Mean Solar Day, because the rotation of the Earth on its axis, and the orbiting of the Earth around the Sun, are both counterclockwise, as viewed from above (or north of) the Ecliptic Plane. See planetary retrograde motion for an example of the opposite situation.
The reason that the Solar Day varies around the Mean Solar Day is that the Earth moves at different speeds through its orbit around the Sun. This is in keeping with Kepler's Second Law of Planetary Motion.
Please note that the Mean Solar Day changes over a long period of time, due to the slowing of the rotation of the Earth due to tidal forces exerted on the Earth primarily by the Moon. For example, the Mean Solar Day was about 23 hours about 250 million years ago.
