Many flowers produce nectar. what is a purpose of nectar? to remove excess water to shield petals from damage to attract birds and insects to trap pollen and bees

The correct answer would be to attract birds and insects to trap pollen and bees.

Nectar is sugar rich product produced by plants in order to attract insects.

The insects get the food in the form of nectar and in return they help in pollination and thus, help in reproduction of the plants.

This is also an example of mutualism in which plants and insects get benefits from each other.

answer:

sequence 1- deletion

                  2- duplication

                  3- insertion

                  4- substitute

                  5- inversion

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
