Which of the following organisms can have all of the energy it uses to move, grow, and survive traced back to radiant energy from the Sun? a tree
a human
a flower
a bacterium
a fish

a tree and a flower

Explanation:

tree and flower

Explanation:

The trees and flowers are considered the primary producer of food in any food chain. They entrap the solar energy from the sun through green leaves and convert it into food in the form of its various producers. As the consumer eats the plant only 10% of the energy of the plant is transferred to it, likewise in all the trophic levels of the food chain the energy transferred from one level to another is just 10 % of its preceding level. This means that most of the energy lies with the producer and thus they can use 100% of their energy for moving, growing, and surviving

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.
