Summary. The species interactions discussed above are only some of the known interactions that occur in nature and can be difficult to identify because they can directly or indirectly influence other intra-specific and inter-specific interactions.s a result, ecological interactions between individual organisms and entire species are often difficult to define and measure and are frequently dependent on the scale and context of the interactions (Harrison & Cornell 2008; Ricklefs 2008; Brooker et al. 2009).
Generally, people get sick within four to 48 hours after eating spoiled or contaminated food, says HowStuffWorks. According to KidsHealth, food poisoning results from eating foods that contains harmful bacteria or toxins. Bacteria are found everywhere, especially in spoiled leftovers.
Food poisoning occurs when you eat or drink something that is contaminated. Within a few hours or up to one day, you will begin to feel sick to your stomach. Every time you eat something, you will experience diarrhea. Diarrhea from food poisoning can last for up to two weeks after the initial episode. Food poisoning is commonly caused by a lack of proper hand washing, food handling and eating leftovers.
