Producers and Consumers

Grass are a kind of producer who feed many herbivores . Rabbits are one primary consumer grass feed . Those carnivores who eat rabbits are secondary consumer .There have some tertiary consumers that might eat the secondary consumers .

Leaves are producer who feed some herbivores such as giraffe . Giraffe are one primary consumers tree leaves feed . Lions are secondary consumers giraffe feed . They don't have tertiary consumers .

 

Locusts are one primary comsumer cabbage feed . Birds are feed themselves by eating those bugs .So birds are secondary conummer . There are some tertiAry consumers that eat secondary consumers such as  sneak .

Cellular Respiration

Section 4.4

     Cellular respiration releases chemical energy from sugar and others carbon-based molecules to make ATP when oxygen is present . Cellular respiration is a aerobic process . Cell respiration take place in mitochondria , which are often called "powerhouses" because they made most of a cell's ATP . Glycolysis  splits glucose into two three-carbon molecules and makes two molecules of ATP. Glycolysis was probably among the first biochemical processes to evolve .The Krebs cycle produces molecules that carry energy to the second part of cellular respiration.

  

  Eukaryotes   break down molecules from food to produce ATP . Cellular respiration produce ATP by breaking down sugars . Cell respiration take place in mitochondria . Glycolysis are necessary in cell respiration . The products of glycolysis are broken down in mitochondria to make more ATP .

Section 4.5

   Glycolysis is an ongoing process in all cells .It takes place in the cytoplasm before cellular respiration, and it does not require oxygen.The pyruvate and NADH produced by glycolysis are used for cellular respiration when oxygen is present.The Krebs cycle breaks down citric acid and transfers energy to the electron transport chain.The electron transport chain is the second main part of cellular respiration.

  

 There are three stage of cellular respiration : Glycolysis ,  the Krebs cycle and the electron transport chain .The pyruvate and NADH produced by glycolysis are used for cellular respiration when oxygen is present.The Krebs cycle breaks down citric acid and transfers energy to the electron transport chain .The electron transport chain takes place in and across the inner membrane of a mitochondrion .Oxygen is needed at the end of the process to pick up electrons that have gone through the chain .
