What gas do animals need to make food?

oxygen
All animals need oxygen. Animals that live in water get their oxygen from the water. Plants need gases from the air, too. They need carbon dioxide to make food.

Which gas is used by animals for energy?

When an animal breathes, it takes in oxygen gas and releases carbon dioxide gas into the atmosphere. This carbon dioxide is a waste product produced by the animal’s cells during cellular respiration. Cellular respiration occurs in the individual cells. Digested foods have chemical energy stored in them.

Which gas all animals need to release energy from food?

During cellular respiration animal cells combine oxygen with food molecules to release energy to live and function. Remember that cellular respiration produces carbon dioxide as a waste product. Animals use energy to grow, reproduce, and to function.

What are needed for animals to make energy?

Animals benefit indirectly because they, too, must have sources of food. Animals either eat plants to obtain chemical energy in the form of glucose or they eat other animals that ate plants. Energy moves from the Sun to plants to animals. Photosynthesis is necessary for that energy flow.

What gas is breathed in when you inhale?

When you inhale (breathe in), air enters your lungs and oxygen from the air moves from your lungs to your blood. At the same time, carbon dioxide, a waste gas, moves from your blood to the lungs and is exhaled (breathe out). This process is called gas exchange and is essential to life.

What do fish have instead of lungs?

But instead of lungs, they use gills. Gills are branching organs located on the side of fish heads that have many, many small blood vessels called capillaries. As the fish opens its mouth, water runs over the gills, and blood in the capillaries picks up oxygen that’s dissolved in the water.

What do animals use carbon for?

The carbon combines with oxygen to form carbon dioxide (CO2) and is released back into the atmosphere as a waste product when animals breathe and exhale. In the process of respiration, oxygen combined with the carbohydrates and proteins in the dinosaur’s cells to provide energy for its daily activity.

Which gas is used by plants for respiration?

aerobic respiration uses oxygen and produces carbon dioxide….Photosynthesis and respiration in plants.

Conditions	Photosynthesis v respiration	Overall result
Dim light	Photosynthesis rate equals respiration rate	Neither gas is taken in or given out
Bright light	Photosynthesis rate greater than respiration rate	Carbon dioxide taken in, oxygen given out

What organ in animals release carbon dioxide from the body?

lungs
Excretion gets rid of carbon dioxide, water, and other, possibly harmful, substances from your body. Your lungs excrete carbon dioxide as you breathe out, your kidneys filter out nasties to produce urine, removing nitrogen waste from your body, and your skin sheds excess salt through sweat.

What kind of energy does an animal need?

energy. They need energy to move, to make sounds, to see and to hear. The young eagle uses energy to keep watch. When it sees danger, it needs energy to fly away. Green plants make their own food. They use sunlight and ingredients from soil, water, and air to grow. Plants need energy too, but they do not eat like animals.

What kind of gases do animals take in for photosynthesis?

What is Photosynthesis. Animals take in gases through a process called respiration. During the respiration process, animals inhale all of the gases in the atmosphere, but the only gas that is retained and not immediately exhaled is oxygen. Plants, however, take in and use carbon dioxide gas for photosynthesis.

Where do all animals get their oxygen from?

The answer would be : All animals need oxygen to make energy from food. We get this oxygen from the air that wa breathe.

Where do living things get their energy from?

The common carp is an omnivore. Food chainsshow where living things get their energy. All food chains start with the sun. Green plants make their own food using sunlight. Animals must eat plants or other animals to live and grow. In this Hudson River food chain, arrows show where each living thing gets energy. The sun gives energy to the plant.
