Which do animal cells need in order to maintain homeostasis a: light energy b: carbon dioxide c: chemical energy d: carbon monoxide

All animal cell need B

some are behavioural changes
panting
shade seeking behaviour- to reduce radiation exposure
migration- to move to more suitable climates
curling up- reduce surface area to volume ratio

others include structual changes (you can not change this)

large size- for low surface to volume ratio
round shape/short extensions- low surface to area volume ratio

then you have physiological changes this is done by either the hormone (endocrine) system or nervous system

vasioconstriction- reduce blood flow to extemeties
shivering- increase metabolic heat produced

as you can see these adaptions are used to create a negative feedback.What this means is it is the oposite to the stimulas. For example if you get cold(stimulas) you may shiver which creates heat and warms your body( the opposite effect of being cold and thus the reverse to the stimulas)

note there is some that create positive feedback as well.

hope this helps

The answer is b hope this

A- a reduction in biodiversity
