1. An insect’s resource-seekin
1. An insect’s resource-seeking behavior is called a foragingstrategy. What factors other than flower characteristics mightinfluence the foraging strategies of the insects you observed? Isit possible that wind or sun exposure, proximity to shelter,humidity, or other site characteristics are in part responsible fordifferences in pollination frequency?
2. In natural plant communities, different species often opentheir flowers at different times of day or at different times ofyear. Why might this be advantageous to all members of thecommunity?
3. What do you notice about flower color, scent, shape, ororientation that might affect attractiveness to different kinds ofpollinators? Does flower structure explain any patterns in insectpreference?
4. How are flowers shaped to maximize pollen transfer? Are theinsects forced to brush against the male parts of the flower(called anthers) in order to enter the flower or in order to accessthe nectar? How do you think pollen might be transferred to thereceptive surface (called the stigma) of the female floralparts?

Answer:
1. There are many factors, which ifluence the foragingstrategies of insects. Foraging strategies can be influenced bygenetics, presence of predators. Honey bees foraging strategy isinfluenced by genetics. Presence of predators will also influencethe foraging behaviour of insects. For example insects will notdepend a particular type of plant, if it is habitat of predator.Wind, sunlight, humiduty, etc will make difference in pollinationfrequency. High temperature, rain etc will decrease the pollinationfrequency. During rainy season the pollen will become clumpy, itreduce the pollination frequency.
2. In nature different species flower bloom in different times,because they bloom when there is best chance of pollination, somerequire large amount of sunlight, whereas some require less. Thiswill ensure the avaliability of food(nector, fruits) for insects,animals. For example it will helps the honeybees to collect nectorirrespective of time or season.
3. Pollinators are attracted to different coloured flowers, forexample insects like bees are atracted to brighter colours likeviolet, whereas birds are attracted to pink or purple colours.Brighter coloured flowers have higher chance of getting pollinated,whereas flowers which have less broghter colour has less chance ofpollination. Some flowers secreate larger amount of nectar, strongscent to attract the pollinators towards the flower.
4. Most of the flowers have open access nature, so that manyinsect can visit the flower, the anthers and stigma are present ineasily accessible area, so when an insect visit a flower fornector, the pollen will easily sick into its body parts and thisincrease the chnace of getting pollinated.
