Read about the tiger at https://bigcatrescue.org/tiger.htm
Siberian tigers have yellowish, thick fur. Bali tigers have brighter and shorter fur. In one species of tiger, the gene for yellowish fur is dominant while the gene for reddish-orange fur is recessive. A male with yellowish and a female with yellowish fur produce a female offspring with reddish-orange fur. Which most likely describes the genes of the parent tigers?
- Both parents carry the recessive gene
- The male parent carries the recessive gene but the female parent does not
- The female parent carries the recessive gene but the male parent does not
- Neither parent carries the recessive gene; the reddish-orange fur was a spontaneous mutation
Biomass is the mass of living tissue found in living organisms (not water) For example, a human weighing 100 kilograms would only have 30 kilograms of biomass per meter squared because 70% of their mass is water. In a marsh in a Sumatra ecosystem, the weight of the biomass was calculated :
Producer Consumer Consumer Consumer
809 grams 37 grams 11 grams 1.5 grams
per Meter2 per Meter2 per Meter2 per Meter2
According the the numbers above, which trophic level would have the SMALLEST percentage of the total biomass?
- Primary producer
- Primary consumer
- Secondary Consumer
- Tertiary Consumer
