Existing landfilles are generally considered sufficient to serve as the sole means of disposing of the nations waste for the foreseeable future. true/false

False.

Explanation:

The waste may be defined as any undesirable substance that left out after using the particular substance. The waste substance can be defined into two main classes - biodegradable and non biodegradable waste.

The one way to dispose out the waste product is the landfilles. The substance that cannot be degraded by any other means can be land filled. But this waste disposal method is not enough to contain the whole nation waste and all the waste cannot be land filled.

Thus, the correct answer is false.

poor water quality affects most estuarine organisms, including commercially important fish and shellfish. the pollutants that have the greatest impact on the health of estuaries include toxic substances like chemicals and heavy metals, nutrient pollution (or eutrophication), and pathogens such as bacteria or viruses.

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
