The correct answer is option (A) The snake population will decrease rapidly and the grass population will increase rapidly.
A food chain can be defined as a linear sequence of organisms through which the nutrients and energy flow as one organisms feeds on the other. Each level of the food chain is called the trophic level. They show organisms starting from the producers and end with consumers or sometimes with detrivores or decomposers. The producers which use solar energy and prepare their food occupy the first trophic level, followed by the primary, secondary, tertiary, quaternary consumers occupying the next trophic level.
In the terrestrial food chain given above, grass → rabbit → snake → Hawk, the decrease in the any population will effect the other organism at a different trophic level of the food chain. A sudden decrease in the population of rabbits due to trapping will rapidly decrease the snake population due to scarcity of food and the grass population will increase rapidly due to the lack of the consumers which are the rabbits.
One similarity you could draw between the two acceptance speeches is the overall tone of <u>hopelessness</u>.
DDT was used to control the malaria-causing mosquitoes. DDT killed them but accumulated in the soil also, through which entered animals and humans via food. There, it gets stored in the fat tissue and is very difficult to breakdown. The predator animals, feeding upon smaller animals, got DDT in their bodies from the smaller animals and DDT thus, magnified to the top level of the food chain. The government realized this and banned DDT.
Scientific inquiry refers to the stages and processes used to explain and investigate a question or problem of a scientific nature. The nine activities that scientists engage in as a part of scientific inquiry are; observation, defining the problem, forming a study question, researching the problem, stating the hypothesis, experimenting and gathering data, analyzing the results, reviewing the findings and communicating using different format.
The SI unit for density is kilograms per cubic meter. However, often grams per cubic centimeter or grams per milliliter, which are equal (1 cubic centimeter = i milliliter), is used. In order to find the density of a substance, you divide its mass by its volume.
