Communities and Biomes/ True or False?

Hey I need some help on my homework. Thanks.

True or False

1. The Interactions of abiotic and biotic factors result in conditions that are suitable for some organisms but not for others.

2. Food availability and temperature can be biotic factors for a particular organism.

3. A limiting factor is any biotic or abiotic factor that promotes the existence, numbers, reproduction, or distribution of organisms.

4. At high elevations where the soil is thin, vegetation is limited to large, deep-rooted trees.

5. Factors that limit one population in a community may also have indirect effect on another population.

6. Tolerance is the ability of an organism to withstand fluctuations in biotic and abiotic environmental factors.

7. A population of deer would become as conditions move away from optimal toward either extreme of the deer's range of tolerance.

8. Different species may have different ranges of tolerance.

Thank you.
