Blank 1 is oxygen
Blank 2 is carbon dioxide
During cellular respiration ,every living thing in this food web uses oxygen and release carbon dioxide into the environment.
Cellular respiration can be described as a process which every cell in an organism's body carries out to generate energy. Cellular respiration is a process by which sugar (glucose) and oxygen are converted into carbon dioxide and water with the release of ATP molecules. ATP is the driving energy source for each cell. Each cell requires ATP to carry out normal cell functions. The excess carbon dioxide produced by this reaction is released into the atmosphere.
Plants are the only living things that do quite the opposite.
this is because oxygen atoms bind to the hydrocarbons from food (glucose etc.) during formation ATP (Kreb's cycle). Carbon dioxide is a basic waste product which is removed because it increases the acidity of the blood if build-up occurs.
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.
- 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.
answer; i believe the correct answer is (data); /// good luck
