Answer 1

Here are the answers to your questions:

**Question 1**
A) **Amazon rainforest** - The Amazon rainforest is known for its high biodiversity and complexity, making it more resilient to changes than the other ecosystems listed.

**Question 2**
A) **mountain lion** - The mountain lion is often considered a keystone species because its presence or absence can significantly affect the structure of the ecosystem, particularly in controlling the populations of other species.

**Question 3**
A) **genetic diversity** - Genetic diversity is often the hardest to measure precisely because it requires detailed genetic analysis and is less observable than other forms of diversity.

**Question 4**
A) **desert** - Deserts generally have the lowest species diversity compared to ecosystems like coral reefs, grasslands, and tropical rainforests, which support a wider variety of species.
