A food web shows how energy moves from organisms. Producers have 100% of the energy. From there, 10% is transferred to each of the next trophic level.
This is not a food chain because in a food chain, energy simply travels from one organism to the next. A food web is where you have many overlapping food chains. A prey predator interaction is simply the relationship two organisms have. It doesn’t focus on the path of energy through a community. It’s simply like saying “lions hunt gazelles”. This is not mutualism. Mutualism is an example of a symbiotic relationship where both organisms benefit. An example of this is an oxpecker and a rhinos. Rhinos are rid of pests and oxpeckers get food. Both organisms benefit. Other symbiotic relationships include commensalism (one organism benefits, other unaffected) and parasitism (one organism benefit, other is harmed).
True. Shivering is a bodily function in response to cold in warm blooded animals/human. When the core body temperature drops shivering reflex is triggered to maintain homeostasis. Skeletal muscles begin to shake in small movements creating warmth by expending energy.
