Calculating the energy requirements of invertebrates.
Hi. I am a student (not at uni yet) and I have an assignment on the diet and energy requirements of two animals. One I have chosen is a theraphosidae spider (no specific species). The problem is, I have been told by my assessor to completely start the whole thing all over again (I had virtually finished it 😩) because the formula for calculating the RER of a small animal does not apply to invertebrates.
I was wondering whether there is a way of calculating the energy requirements of an invertebrate (specifically a tarantula)?
I can’t find anything online about it, but Google searches are getting harder to get reliable results from. I’m honestly despairing at the thought of having to rewrite the whole assignment after how much effort I put into it.
Thank you to anyone who can help.
