Answer:
presence of cells
Explanation:
All living things are composed of cells. A cell can be defined as a complex biological arrangement that has all the structures and materials required for life. Cells carry out specialized functions such as, for example, metabolic functions to convert nutrients from food into energy (ATP), and reproduce by mitosis and/or meiosis. Thus, the cell is known to be the basic unit of life.
Answer:
Deforestation is both the removal of trees and the permanent retasking of the land for non-forestry purposes. Therefore, since tree roots help aerate soil and improve soil water retention, this permanent removal of trees reduces the amount of water that soil can absorb and increases the amount that will perforce flow over the ground as runoff. Increased surface runoff leads to flooding.
Explanation:
Answer: B. Amount of matter produced by the producers should be more than that of the consumers.
Food web defines a interconnection between different food chains and transfer of energy at each trophic level. According to the ten percent law 10% energy is lost from each trophic level. At the first trophic level there are producers. Producers occupy the only one level in the trophic levels the rest is occupied by consumers this shows the category of consumer is more than producer. Therefore, for successful food web food availability should be more at initial trophic level hence amount of matter produced by the producers should be more than that of the consumer.
