Answer;
-Communities that experience moderate disturbances often exhibit greater species diversity than other communities,
-Moderate disturbances create openings/opportunities for colonizing species
Explanation;
-Ecological disturbances may be generated by abiotic, or nonliving, forces such as weather and wildfires, or they may occur as a result of biotic, or living, forces such as disease and invasions of exotic species.
-Disturbance can result from natural causes or from the activities of humans.
Disturbance can be caused by physical stressors such as volcanic eruptions, hurricanes, tornadoes, earthquakes, and over geological time, glacial advance, and retreat.
-Humans can also cause physical disturbances, for example, through construction activities. Wildfire is a type of chemical disturbance caused by the rapid combustion of much of the biomass of an ecosystem and often causing mortality of the dominant species of the community such as trees in the case of a forest fire.
Answer:
Gel-like fluid present within the cell membrane (excluding nucleus) is termed as cytoplasm of the cell.
It serves various functions in the cell such as:
- It supports and hold all the cell organelles and cell parts.
- It serves as the site of most of the cellular activities or processes.
- It provides shape to the cell.
- It contains the cytoskeleton (actin filaments, intermediate filaments, and microtubules) of the cell which helps in maintaining the cell shape, the movement of materials within the cell, cell division and movement of the cell.
Hence, all options are correct except "determines which substances can enter or leave the cell".
Plasma membrane of the cell determines which substances can enter or leave the cell.
