Let's solve this step by step by comparing the animal populations
before 1960 and
after 2017 for each species. We need to determine whether the population
increased,
decreased, or
stayed the same by choosing the correct comparison sign:
>,
=, or
<.

1. Toucan
- Before 1960:
914
- After 2017:
49
Compare:
914 > 49 → Population
decreased
✔ Choose:
>

2. Blue Morpho Butterfly
- Before 1960:
422
- After 2017:
462
Compare:
422 < 462 → Population
increased
✔ Choose:
<

3. Jaguar
- Before 1960:
350
- After 2017:
85
Compare:
350 > 85 → Population
decreased
✔ Choose:

4. Three-Toed Sloth
- Before 1960:
511
- After 2017:
399
Compare:
511 > 399 → Population
decreased
✔ Choose:

5. Golden Lion Tamarin Monkey
- Before 1960:
602
- After 2017:
608
Compare:
602 < 608 → Population
increased
✔ Choose:
<

6. Hyacinth Macaw
- Before 1960:
307
- After 2017:
307
Compare:
307 = 307 → Population
remained the same
✔ Choose:
=

✔ Final Answers:
| Animal | Before 1960 | Sign | After 2017 |
|-------------------------|-------------|------|------------|
| Toucan | 914 |
> | 49 |
| Blue Morpho Butterfly | 422 |
< | 462 |
| Jaguar | 350 |
> | 85 |
| Three-Toed Sloth | 511 |
> | 399 |
| Golden Lion Tamarin | 602 |
< | 608 |
| Hyacinth Macaw | 307 |
= | 307 |

🌿 Conclusion:
This shows that most rainforest animal populations have
declined due to human activity, but some species like the
Blue Morpho Butterfly and
Golden Lion Tamarin Monkey have
increased, possibly due to conservation efforts. The
Hyacinth Macaw population stayed stable.
This comparison helps scientists understand biodiversity changes and prioritize conservation actions!
