The image shows a rain forest ecosystem. the energy from plants, or producers, acts as the starting point of energy in the ecosystem. this energy is transferred to other organisms in the food web. in which two ways is the total amount of energy conserved in the ecosystem? some energy is transferred to the organisms, and the remaining energy is released into the ecosystem as thermal energy. bacteria eat the dead bodies of organisms to release the organisms’ stored energy into the atmosphere. some energy is transferred to the smaller organisms, and the rest is stored in the bodies of larger animals. some energy is transferred to the organisms, and the rest is released by plants in the form of carbon dioxide. bacteria eat the dead bodies of organisms, obtain all the energy, and store it in their bodies.

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.

explanation:

b. lithosphere, asthenosphere, mesosphere   is the answer most likely
