Population Growth
R and K Selection
R and K selection are concepts in ecology used to describe traits in the fluctuation of a population or population dynamics. For example, they describe the life-association traits between parent and offspring, such as quantity or number of young ones born at a time, quality of parental care, the age to maturity, and reproductive effort.

Kits remain in the care of the colony until two to three years of age. Century plants are flowering plants native to Mexico. Century plants live 10-30 years and flower only once in their lifetime and perish shortly after. THeir giant flowering stalks can reach up to 9m long but they reproduce primarily via suckers. Honeybees live in colonies as large as 50,000 bees. Only the queen lays eggs and lays up to 2,000 per day. The house mouse is a polygamous mammal with the gestation period of about 20 days and a litter size of up to 14. Mice nurse their young until about 20 days.
- The fungus Botrytis is known to cause rot in fruit and decrease the harvest. In an effort to limit the damage, some agriculturalists spray the soil of orchards with fungicides. The effect of fungicides is not specific for Botrytis and kills most fungi in the soil. In a short answer, predict what would happen to the yield of grapes following fumigation and explain the rationale for your prediction.

Table 6.2 shows the results of a greenhouse experiment which examined the effects of density on the germination and growth of barley. Plants were grown for two weeks in 10- cm diameter pots kept in identical environmental conditions and watered regularly. At the end of the experiment the plants were cropped by cutting the stems at the soil surface. Based from the given table and graph, discuss the data and the relationship of the two factors (Mean wet biomass of plants (g) and Number of plants that germinated). Then, what is the effect of density to the Mean wet biomass of plants?A scientist is studying the effect a new fertilizer has on the root growth of bean seedlings. Three groups of plants are grown in the same location in a greenhouse, each receiving the same amount of sunlight and water every day. The scientist measures the length of the roots for each plant every day. The scientist then calculates the mean for each group for five days. The results are shown in the following table.

- Which of the following is true about Liebig's Law of the Minimum? * The growth of a plant is affected by one limiting factor at one time. The growth of a plant is affected by multiple limiting factors at one time. The growth of a plant is not affected by multiple limiting factors at one time. The growth of the plant is not affected by one limiting factor at one time. According the Shelford's Law of Tolerance, the organisms wide environmental factor tolerance limit show * narrow distribution with low population size narrow distribution with high population size wide distribution high populations size wide distribution with low population size If you are having a fever, you are in your * zone of optimal tolerance zone of intolerance zone of physiological stressWhy is the growth curve for most populations S-shaped?Label this logistic growth curve:
