What do all living things need to live?
Most living things need food, water, light, temperatures within certain limits, and air. Living things have a variety of characteristics that are displayed to different degrees: they respire, move, respond to stimuli, reproduce and grow, and are dependent on their environment.
Do all organisms need a place to live?
all organisms need a place to live- a place to get food, water and shelter. space could be either the freezing Antarctica or a scorching desert; regardless, it’s surroundings must provide what it needs to survive.
What do all organisms need quizlet?
All organisms need oxygen, energy, water, and heat. Some organisms need CO2 to produce food. Why do animals need food and oxygen? Animals need food because food is the energy to survive and grow .
What two things do all organisms want?
In order to survive, all living things need air, water, and food. Animals obtain their food from plants and other animals, which provides them with the energy they need to move and grow. An animal’s home (habitat) must provide these basic needs (air, water and food) along with shelter from bad weather and predators.
Which best explains why organisms need food?
Which best explains why organisms need food? Food is the source of energy required for growth and repair of tissues. Food is the source of water needed to hydrate the surface of cells. Food provides the oxygen necessary for plant and animal survival.
Which best explains why energy transfer is not 100% efficient?
The second law explains why energy transfers are never 100% efficient. Because ecological efficiency is so low, each trophic level has a successively smaller energy pool from which it can withdraw energy. This is why food webs have no more than four to five trophic levels.
What is the process of generating energy from the food we eat?
The process of getting energy from your food is called cellular respiration.
How quickly does sugar enter the bloodstream?
If you are at risk for low blood sugar levels because of diabetes or some other health condition, you need to keep with you at all times some type of food that can quickly raise your blood sugar level. Eating quick-sugar food puts glucose into your bloodstream in about 5 minutes.
Can glucose be broken down without oxygen?
If oxygen is present, then glucose can be broken all the way down into carbon dioxide and water. In the absence of oxygen, the cell uses a process called anaerobic fermentation. or simply fermentation.
What happens when glucose is broken down in the absence of oxygen?
Glucose –> carbon dioxide + water + energy. in the absence of oxygen in which glucose breaks into alcohol and carbon dioxide with release of energy.
When glucose is Catabolised in the absence of oxygen?
Question 3When glucose is catabolized in the absence of oxygen, Selected Answer:pyruvate formed in glycolysis will generally be converted to acetyl coenzyme A, which will enter the Krebs cycle.Answers:pyruvate formed in glycolysis will generally be converted to lactate.
What process does not require oxygen?
Answer: The process that does not require oxygen is fermentation. Explanation: Fermentation is an alternative route of cellular respiration for obtaining energy, in the absence of oxygen.
What is the presence and absence of oxygen?
One occurs in the presence of oxygen (aerobic), and one occurs in the absence of oxygen (anaerobic). Both begin with glycolysis – the splitting of glucose. Cellular respiration that proceeds without oxygen is called anaerobic respiration.
What will happen if there is an absence of oxygen in the materials?
If there was no oxygen available, aerobic respiration would stop and organsims that rely on aerobic respiration would die. Without aerobic respiration, the anaerobic process of glycolysis produces a net yieldof 2 ATP from one glucose molecule.
What is the result of absence of oxygen in the materials?
1. The presence or absence of oxygen in the materials may result in theA burning of the materialsB.
