Answer:
A plant cutting is a piece of a plant that is used in horticulture for vegetative (asexual) propagation. A piece of the stem or root of the source plant is placed in a suitable medium such as moist soil. If the conditions are suitable, the plant piece will begin to grow as a new plant independent of the parent, a process known as striking. A stem cutting produces new roots, and a root cutting produces new stems. Some plants can be grown from leaf pieces, called leaf cuttings, which produce both stems and roots. The scions used in grafting are also called cuttings.
Propagating plants from cuttings is an ancient form of cloning. There are several advantages of cuttings, mainly that the produced offspring are practically clones of their parent plants. If a plant has favorable traits, it can continue to pass down its advantageous genetic information to its offspring. This is especially economically advantageous as it allows commercial growers to clone a certain plant to ensure consistency throughout their crops.

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.
<u>Answer:</u>
Composting food scraps in the cafeteria to reduce landfill waste would have the greatest impact in reducing the school’s ecological footprint.
Option: (C)
<u>Explanation:</u>
- Reducing the ecological footprint means bringing about some changes in lifestyle and living to improve the biocapacity.
- Compositing food scraps in the cafeteria to reduce landfill waste is the best option that the environmental club can apply to reduce the school's ecological footprint.
- This step can help to increase productivity of soil as well as reduce waste in landfill site.
- The option of incineration of trash causes air pollution. Likewise, reducing recycling bins will not be helpful in decreasing the ecological footprint.
- Instead, it causes the unmanaged collection of trash in school environment.
