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.

Explanation:
. Chemical digestion is the biochemical process in which macromolecules in food are changed into smaller molecules that can be absorbed into body fluids and transported to cells throughout the body. Substances in food that must be chemically digested include carbohydrates, proteins, lipids, and nucleic acids.
2.A fat molecule, such as a triglyceride, consists of two main components—glycerol and fatty acids. Glycerol is an organic compound with three carbon atoms, five hydrogen atoms, and three hydroxyl (–OH) groups.
3. If it's in the table, it's an element! Atoms can join together - they form bonds together - to make MOLECULES. For example, two atoms of hydrogen hook together to form a molecule of hydrogen, H2 for short.
4. When atoms join together to form molecules, they are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons between the atoms. It is only the electrons in the outermost shell that ever get involved in bonding.
A compound is a molecule made of atoms from different elements. There are two main types of chemical bonds that hold atoms together: covalent and ionic/electrovalent bonds. Atoms that share electrons in a chemical bond have covalent bonds. An oxygen molecule (O2) is a good example of a molecule with a covalent bond.
5.Beginning with energy sources obtained from their environment in the form of sunlight and organic food molecules, eukaryotic cells make energy-rich molecules like ATP and NADH via energy pathways including photosynthesis, glycolysis, the citric acid cycle, and oxidative phosphorylation.
Answer:No
Explanation:Plants will not just have to rely on one animal to help reproduce. Plants can mimic things such as scents or looks to be an incentive for other animals. Wind and water can also help transport pollen. Plants always have pollinators such as wind, water, insects, and animals. Plants use mimicry in order to attract the biotic pollinators. Plants will never have trouble reproducing because they have so many different pollinators.
