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.
Usually though, the main symptoms from eating moldy food will be nausea or vomiting from the bad taste and smell of the moldy food. Mold on grain products is the worst-e.g. moldy bread, moldy muffins, etc. - and should be thrown out.
