Explanation:

1. Diversity: Diversity as a term is broad and might be used in many aspects, referring to things variety. Diversity in biological terms refers to the present or the past forms of life inhabiting a natural environment.
2. Stability: Related to the resilience concept. Stability depends on the quantity and magnitude of disturbances affecting an ecosystem. If there are no disturbances, the ecosystem is stable. If there are some or many disturbances of small magnitude, the ecosystem remains relatively stable, with a high resilient capability. But when the ecosystem is affected by frequent and severe disturbances, it loses stability and might be seriously affected.
3. Biodiversity: Defined as the different species living in a certain restricted area. It is the variability of living beings in a natural environment, involving all the species on the planet and their genetic material. This variety includes all plants, animals, fungus, and microorganisms living in a certain place, their genetic variability, and the ecosystems these species conform.
4. Cosmopolitan: Referred to as any taxonomic group that live all around the world. Species might be cosmopolitan, or genera, or classes. Sometimes a superior taxonomic group is cosmopolitan, but the species composing it are not.
5. Endemic: Referred to species or any other taxonomic group restricted to a certain area or region, which provides all the environmental requirements of these organisms. They are usually small groups that might be in danger of extinction due to any alteration that might change their environment. They might also be a new species that did not have enough time to disperse yet.
6. Ecosystem: Ecosystems include all the biotic, physical, and chemical components of nature, continuously interacting and depending on each other. The ecosystem is composed of living and non-living things that interact and depend on each other. These are the biotic and abiotic factors.
7. Population: Groups of individuals from the same species, with similar characteristics, capable of crossing, leaving offspring, and living in the same habitat at the same time.
8. Species: Organisms that are morphologically and genetically similar, that can mate, reproduce and leave fertile offspring to the next generation. Members of populations.
9. Exotic: It refers to new species that establish in a new area far or out of their original distribution range. The dispersion of these species to new areas might be accidental or intentional. Once established, these species might be considered invasive if their reproductive rate increases, if their population over-growth, and there is a negative interaction with native species.
