Answer:
Competition for food happens when there is a limited amount of food resources available. The members of a species that eat that food who are best adapted to access the food are more likely to reproduce and pass on their genes to the next generation.
For example, we have a bird feeder with a narrow opening for food. The small-headed birds can reach the food, the bigger-headed birds cannot. If this was the only food source for this area, then over time, there would be more smaller-headed birds than large-headed birds, due to the competition for food and success/lack of success.

Explanation:
This question is incomplete because of the absence of the graph. However, the independent variable of an experiment is the variable that is not affected by any other variable during the course of the experiment but is however intentionally or unintentionally predetermined by the researcher conducting the experiment. For example, in an experiment to determine the effect of age on blood pressure; age is the independent variable because the age class/groups of the individuals to be used can be determined by the researcher also the age cannot be affected by the pressure (the age of a person cannot change because of an increase/decrease in blood pressure).
Also, the control of an experiment is the variable/data in which other data in the same experiment are compared to. For example, in an experiment to determine the effect of a substance (such as sepin-1) on the growth of cancer cells (using a culture medium), the control can be the culture medium that was not given any substance or the culture medium that was given a pure substance of no effect like water. This means, in this control culture medium, the cancer cells will continue to grow normally while that growth will be compared with what is seen in the culture medium treated with sepin-1.
Porous and Impermeable Rock These pores, or tiny holes, result in the rock's porosity. If water can move through a rock, the rock is permeable. Eventually, the water reaches a layer of rock that is not porous. This rock is impermeable.
