Question

wrap - up discussion questions - how do abiotic factors affect where animals and plants live? - can abiotic factors change over time? give an example. - why do you think more species live near the equator?

Explanation:

For the first question, we consider the basic requirements of plants and animals and how abiotic factors meet or limit those needs. For the second, natural and human - induced changes in abiotic factors are considered. For the third, the unique abiotic conditions near the equator that promote biodiversity are highlighted.

Answer:

• How do abiotic factors affect where animals and plants live?

Abiotic factors like temperature, water availability, sunlight, and soil type determine the habitats of plants and animals. For example, cacti are adapted to arid regions with low - water availability, while salmon need cold, oxygen - rich water to survive.

• Can abiotic factors change over time? Give an example.

Yes, they can. Climate change is a prime example where global temperatures (an abiotic factor) are rising over time due to increased greenhouse gas emissions. Another example is the change in water levels in a river due to seasonal rainfall patterns or construction of dams.

• Why do you think more species live near the equator?

Near the equator, there is a more stable and warm climate throughout the year, abundant sunlight, and high levels of precipitation. These abiotic factors create a more diverse range of habitats and food sources, which can support a greater number of species.
