Question

species abundance:
have all of the animal types recovered to their 1950 abundance levels?
(chart: x - axis: animal type (fish, crabs, pelicans, insects); y - axis: number of organisms counted. legend: orange - 1950 abundance, green - abundance at beginning of study (2012), red - abundance at end of study (2022). two buttons: yes!, no! 60% (score))

Explanation:

To determine if all animal types have recovered to their 1950 abundance levels, we compare the 1950 abundance (orange bars) with the end - of - study (2022, red bars) abundance for each animal type:

Fish:

• 1950 abundance (orange bar) and 2022 abundance (red bar) seem to be at the same height (around 16 - 17 on the y - axis). So, fish may have recovered.

Crabs:

• 1950 abundance (orange bar) is around 11, and 2022 abundance (red bar) is around 11. So, crabs seem to have recovered.

Pelicans:

• 1950 abundance (orange bar) is around 9, and 2022 abundance (red bar) is around 9. So, pelicans seem to have recovered.

Insects:

• 1950 abundance (orange bar) is around 19, and 2022 abundance (red bar) is also around 19. So, insects seem to have recovered.

Since for all the animal types (fish, crabs, pelicans, insects) the 2022 (end - of - study) abundance is equal to the 1950 abundance, the answer to the question "Have all of the animal types recovered to their 1950 abundance levels?" is "Yes!".

Answer:

Yes!
