Answer:

Detritus

Explanation:

    Common sense suggests that animals ingest plastic because it is present in the oceans and animals cannot distinguish it from real food (for some animals, such as anchovies, plastic can smell like food). But that does not explain why only certain types of whales - deep-toothed whales such as sperm whales, pilot whales and beaked whales - appear dead on the beaches with plastic in its stomach.

    These species hunt in the depths of the ocean, sometimes more than 500 meters below the surface, in total darkness. They use echolocation to look for food - usually squid. Toothed whales may think plastic waste is food because of its appearance.

Pepsi [2]

Nitrogen Cycle steps:

N molecules breaking apart via nitrogen-fixing bacteria.

Animals ingest nitrogen in nitrate-containing food after plants use nitrogen-containing compounds.

The organic matter decays via decomposers

N2 is formed via denitrifying bacteria.

Explanation:

The nitrogen-fixing bacteria removes atmospheric nitrogen by fixing nitrogen through nitrification. The atmospheric nitrogen cannot be absorbed by plants and hence has to be converted into nitrates. This conversion takes place by nitrifying bacteria present in leguminous plants.

Animals (herbivores) consume the plants that have absorbed nitrogen/

When these animals die, decomposing bacteria acts on the dead organic matter, decomposition takes place through ammonification, converting the organic nitrates into ammonia

The nitrates are converted back again to nitrogen by the action of denitrifying bacteria.  

The nitrogen thus formed is released to the atmosphere

Andrews [41]

Answer:

1) d. observe phenomenon; generate hypothesis, conduct experiment, accept, reject, or modify hypothesis.

C. A study that compares a aroup of people with diabetes to a similar aroup of people without diabetes is an example of a case-control study.

Explanation:

Scientific method is a step by step procedure ranging from observing a problem to actual experimentation that aims at investigating a problem. The steps involved in the scientific method are as follows:

a)observe phenomenon; This precedes every experiment in the scientific method.

b) generate hypothesis: This is a testable explanation given as a possible solution to the observed problem.

c) conduct experiment: The hypothesis is tested via experimentation.

d) accept, reject, or modify hypothesis: Based on the result of the experiment, the hypothesis can be rejected, accepted or even modified.

Question 2:

Case control study is a type of study design that uses or compares a group of affected individuals (by a disease) called CASES and unaffected individuals called CONTROL. In this case, A study that compares a group of people with diabetes (cases) to a similar aroup of people without diabetes (control) is an example of a case-control study.
