Question

which is the oldest living organism?​

Answer 1

Answer:

However, the oldest, precisely measured organism living on Earth today remains, for now, a Great Basin Bristlecone pine tree. Pando the quaking aspen and Antarctic glass sponges could be much older but their ages are assumed from indirect measurements and educated guesswork.

Answer 2

Explanation:

The oldest known living organism is a bristlecone pine that grows in south eastern California's White Mountains, according to ecologist Christopher Earle's online database of conifers. A count of the tree's rings confirms that Methuselah, as the tree is affectionately known, is 4,841 years old
