Thomas Malthus believed that world population had to be brought under control or there would be serious problems in the future. His book, "An Essay on the Principles of World Population," stated that he feared not enough food could be produced to avoid mass starvation if the population wasn't controlled.
Malthus observed that while populations tend to increase exponentially, food production can only grow linearly. This led him to theorize that in the long run, population growth would outstrip the ability to produce enough resources, leading to food shortages and poverty.
Typically, population is limited by the available food sources, although predation and disease are also significant factors. In the case of the human population, people can also choose to have fewer children, and in some countries, that has happened.
The ability of the environment to support a population refers to its carrying capacity, which is the maximum population size that can be sustained based on available resources like food, water, and shelter. When a population exceeds the environment's carrying capacity, it can lead to resource depletion, competition, and potential collapse. Maintaining a balance between population size and available resources is crucial for the long-term sustainability of ecosystems.
An independent country has the ability to govern itself without external interference, has defined borders, a permanent population, the ability to enter into relations with other countries, and is recognized as a sovereign state by the international community.
Biological fitness is typically measured by an organism's ability to survive and reproduce. This can be quantified by factors such as the number of offspring produced, survival rate, and ability to pass on genes to future generations. Fitness can also be assessed in terms of adaptations that enhance an organism's ability to thrive in its environment.
Interbreeding is the mating between individuals of different species or populations. It can increase genetic diversity by introducing new genetic variations into the population. However, excessive interbreeding can lead to a loss of genetic diversity and potentially reduce the population's ability to adapt to changing environments.

Water solvency refers to the ability of water to dissolve a variety of substances due to its polar nature. This allows water to interact with and solubilize many compounds, making it a versatile solvent for many chemical reactions and biological processes. Water's solvency is essential for its role as a universal solvent in nature.
Natural selection selects for traits that increase an organism's ability to survive and reproduce in its environment. These traits are passed on to future generations, leading to an increase in their frequency in the population over time. Ultimately, natural selection acts to improve the fitness of individuals within a population.

A biological stressor has to do with the organism - things like illness, disability, and so on that affect the ability to deal with the environment.

Magnification is the term that refers to the ability of a microscope to increase the size of an object.
Biological species consists of groups of populations. Populations are assigned to the same biological species based on their ability to interbreed and produce fertile (viable) offspring.
