In the natural blank method, the natural physical, chemical, and biological processes in soil and water gradually break down pollutants. what's blank?

Attenuation

Explanation: Natural attenuation: in this method, the natural physical, chemical, and biological processes in soil and water gradually break down contamination or pollutants into harmless components. It helps reduce contamination concentration and soil and water to acceptable levels. Examples of natural attenuation processes include

- dilution or dispersal of pollutants in moving water

- volatilization or reduction of pollutants into vapor

- absorption or attachment of balloons to soil or vegetation

These processes are accomplish naturally. Little or no human intervention is necessary.

explanation:

okay now i don't know this but for the pints nothing else to say bye

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
