Question

1. a small measured area in a forest has 10 individuals present. each of these indwhich is true about the biodiversity index of this area?a. the biodiversity index is 0.1b. the biodiversity index is lowc. the biodiversity index would be higher if there were fewer species amongd. the biodiversity index is 111. an organism has been introduced into a thriving ecosystem and it reproduces quicnot recognize it as prey. the organism is most likely a(n):a. transect speciesb. invasive speciesc. pioneer speciesd. primary species12. which would you expect to find along a line transect?a. the edges of an area being researchedb. a division between habitatsc. a sampling of organisms found in an aread. the total number of organisms in an area13. what two measurements are found on a climatogram?a. temperature in c and temperature in fb. rainfall and vegetation typesc. temperature and number of speciesd. rainfall and temperature14. which of the following is true about vegetation in a biome?a. it can decrease the albedo in an area.b. it can increase the overall temperature in an area.c. the biodiversity can be affected by climate change.d. both a & b are correct.e. both a & c are correct.15. when drawing a food web, arrows representa. which prey is being eaten by a specific predator.b. the flow of energy from one organism to another.c. the trophic level of a certain species.d. the habitat in which an organism lives.16. a biome is cold, treeless and permanently frozen. which type of biome is ita. tundrab. taigac. alpined. chaparral

Explanation:

• Question 10: Biodiversity index calculation requires species richness and evenness data. With only 10 individuals (no species info), we can't calculate exact values (so a and d are wrong). Fewer species lower biodiversity (so c is wrong). A small area with limited info likely has low biodiversity index.
• Question 11: Invasive species are introduced, reproduce quickly, and native predators don't recognize them as prey. Transect species is not a standard ecological term. Pioneer species are first in primary succession. Primary species is not a standard term.
• Question 12: A line transect is used to sample organisms along a line in an area. It's not about edges (a), division between habitats (b), or total number (d).
• Question 13: A climatogram shows rainfall (usually as bars) and temperature (usually as a line graph) over time.
• Question 14: Vegetation can decrease albedo (as darker surfaces absorb more heat). Biodiversity is affected by climate change. Vegetation cools areas (so b is wrong).
• Question 15: In a food web, arrows represent energy flow from one organism (e.g., prey) to another (e.g., predator).
• Question 16: Tundra is cold, treeless, and has permanently frozen sub - soil (permafrost). Taiga has trees. Alpine is mountainous (not permanently frozen in the sense of tundra permafrost). Chaparral has shrubs and is not permanently frozen.

Answer:

1. b. The biodiversity index is low
2. b. Invasive species
3. c. A sampling of organisms found in an area
4. d. rainfall and temperature
5. e. Both A & C are correct
6. b. the flow of energy from one organism to another
7. a. Tundra
