I have a synoptic essay title " how energy is transferred within and between organisms" and i was told that i could write about muscle contractions, im a bit confused about the energy that is being transferred in this topic? I mean i know movement is energy but what specifically is the energy being transferred in the process of muscle contraction ( like the process of myosin heads binding and sarcomeres contracting like what is being transferred in this process)?

I can see the within organisms, food energy to cell respiration and muscle contraction, as you say just describe what happens and how it is ‘fuelled’. Between organisms is less clear, perhaps it’s about one animal giving another a good kicking or you could go with the food chain argument

Do you think i could write about nutrient cycles for the between organisms, im not sure though as it is transferring things like nitrogen and phosphorus not specifically energy?

Transfer of food is transfer of energy. So the carbohydrate, fat, and even protein in the bodies of animals which are consumed and digested by others will be relevant.

So does that mean i can write about the nitrogen and phosphorous cycles?

My memory of these is pretty hazy but aren’t they more about transfer of nutrients between animals and plants to the soil

from what we learned there is about the food chains and biomass which is relatively short and then there is a bit about how fungi and bacteria have an important role in nutrient recycling and then the two cycles, nitrogen and phosphorus
