Dwindle and wane both describe things getting less, along different measures. To dwindle is for a quantity to drain away toward nothing — supplies, numbers, savings, a crowd. To wane is for a strength or intensity to fade — light, power, enthusiasm, influence — and waning is cyclical: what wanes can wax again. Dwindle counts what is left; wane measures how strong it still is.
The moon gives wane its shape and its promise. A waning moon is not losing substance — the moon is entirely there — it is giving back light, and it will fill again, which is why waxing and waning name a cycle rather than a decline. Dwindle has no such return built in. Its subjects are countable and finite: money, members, stock, daylight hours in the sense of how many are left. That is why dwindling supplies is ominous in a way that waning enthusiasm is not, and why interest that has waned can revive without anyone finding the loss strange.
dwindle
To dwindle is to grow steadily less and less — not cut down in one blow but leaking away: savings dwindle, crowds dwindle, hopes and fish stocks dwindle. The word is built on the obsolete verb dwine, 'to waste away', and it keeps that dying fall: what dwindles is on its way toward almost nothing, gradually enough that no single moment looks like the loss. Its favourite companions are quantities — supplies, numbers, reserves — rather than solid objects; a queue can dwindle, a sweater cannot.
wane
To wane is to shrink the way the moon does — by nightly degrees, on a schedule older than the word itself, which comes from Old English wanian, 'to lessen'. Enthusiasm wanes, influence wanes, daylight wanes toward winter. Two graces distinguish it from mere decline: waning is gradual, and it is often part of a cycle — what wanes may wax again. The set phrase 'wax and wane' keeps the whole moon inside the language.

The hourglass and the moon. Dwindle is the sand: countable, one-way, and when the top bulb is empty there is no more. Wane is the moon giving its light back and taking it up again — nothing has actually left, and the return is built in. Ask what is decreasing. An amount that will not come back: dwindle. An intensity that could refill: wane. Reserves dwindle; enthusiasm wanes.

Wane's cycle is why it so rarely sounds final. Because the word arrives paired with wax — the two halves of one lunar month, and by extension of any rise and fall — readers hear the return implied behind it, even in a sentence that never mentions one. Dwindle has no such partner verb and no cycle to belong to, which is why a dwindling supply reads as a warning and a waning enthusiasm reads only as a phase. Where dwindle sits against diminish — the endpoint and the grammar — is drawn on its own page in the 'Related' list below.
Task 1 rewards matching the verb to the subject. Numbers, members, stock and money dwindle; interest, influence, support and enthusiasm wane. The participle is where dwindle earns its keep in a trend paragraph — 'a dwindling share of the market' — while wane suits the Task 2 sentence about attitudes changing over time. Note that wane implies possible return, so using it for a permanent decline slightly undersells your own argument.
