Competition between organisms can be a limiting factor to the population size in several ways. Organisms within a population compete for limited resources such as food, water, and habitat.  

This type of competition occurs between individuals of the same species. As population size increases, competition for resources intensifies. This can lead to increased mortality rates, reduced reproductive success, and lower population growth rates. This type of competition occurs between individuals of different species that share similar resource requirements.

When two species compete for the same resources, the more efficient competitor may outcompete the other, reducing its population size. In some cases, one species may outcompete another to the point where the weaker species is driven to extinction or pushed into a smaller niche. This can limit the population size of the weaker species.

The answer is Ecological footprint. Ecological Footprint is an indication of the productive area of earth needed to produce the resources consumed by that individual.

The term "ecological footprint" refers to the measurement of the productive area of the Earth that is required to sustainably provide the resources and absorb the waste generated by an individual, population, or activity. The ecological footprint concept was developed to quantify the environmental impact of human activities and consumption patterns. It helps understand the sustainability of resource use and the Earth's environmental capacity to support human demands. The ecological footprint considers various factors, such as energy consumption, food production, water usage, land use, and waste generation. It is typically measured in units of global hectares (gha) or hectares per person. By calculating the ecological footprint, it is possible to assess the extent to which an individual or population's consumption patterns are putting pressure on the Earth's resources and ecosystems.

During the waning phases of the moon, less of the moon's near side is seen each night. This statement is false.

During the waning phases of the moon, the illuminated portion of the moon that we can see from Earth decreases each night. The moon goes through phases because as it orbits around the Earth, the relative positions of the sun, Earth, and moon change.  When the moon is in its waning phases, it appears to be getting smaller and less illuminated each night. As a result, less of the moon's near side is visible to us. So, during the waning phases, we see less of the moon's near side each night.

To visualize this, imagine the moon as a circle. As it goes through its waning phases, the illuminated portion of the moon gets smaller and smaller, until we see only a thin crescent or no visible moon at all.  In summary, during the waning phases of the moon, less of the moon's near side is seen each night, which makes the statement false.
