A flea and dog are an example of parasitism, because the flea irritates the dog’s skin and feeds on its blood. Certain bacteria live in the digestive tract of humans, and their relationship is an example of mutualism because the bacteria help humans to break down the food they eat. Cattle egrets eat insects off the back of an elephant, which is an example of commensalism because the cattle egrets benefit without either harming or helping the elephants.

Explanation:

Parasitism can be described as a biological interaction in which one organism gains benefit while the other one gets harmed. For example, in the above-mentioned scenario of flea and dog, the host which is the dog is being harmed while the flea gains benefit.

Mutualism can be described as a biological interaction in which both the organisms gain benefit. For example, bacteria which live in the digestive tract gain shelter and food from the digestive tract. These bacteria benefit humans by breaking down food for them.

Commensalism can be described as a type of biological interaction in which one organism gains benefit while there is no benefit or harm for the other organism. For example, The egrets feed on the insects that are not harming the cattle.

Atp is is our little "pocket" of energy. of course, if you have too little, then it means you have too little energy, and you'll pass out. the way to not have enough, is to have no energy sources (glucose, fats, proteins). you can't have too many atp molecules. cycles like the krebs cycle produce it, but if you have too much of any substrate (or too little for that matter), the cycle stops and atp is no longer made (it stops until substrate levels are such that the process can go on). in any case, this is unlikely since atp is constantly hydrolyzed and remade, even while you're asleep. you won't have too much. if you have zero, you are dead or dying.
