How life processes produce waste?
Animals eat food and absorb the vitamins, nutrients and energy and produce waste from the materials the body does not need. The bodies of dead animals also decay and produce waste.
Why Animal need proteins?
All animals need protein because their bodies use the protein to produce energy. Without protein, animals would not be able to create the cellular reactions that sustain life.
Why do animals need food to stay alive?
Animals need food to stay alive because food gives them nutrients and energy. Nutrients and energy are both important because they help the bodies of animals function.
Why Do Animal Take In Oxygen?
Animals need to breathe to get oxygen. Oxygen burns the food within their bodies and releases energy for various activities.
What is the initial energy source for desert animals?
The energy source is the sun. Plants use solar energy to produce the foods they need for growth. Animals feed on the plants or feed on animals that eat plants.
Why do you need to breathe in oxygen?
oxygen is needed to produce energy from food
What does an animal need in its in environment in order to grow an develop?
Food supplies the energy and material that animals need to grow, develop, and repair their bodies
What does an animal need in it's environment in order to grow and develop?
Food supplies the energy and material that animals need to grow, develop, and repair their bodies
Will cold blooded animals survive without heat energy?
No, cold blooded animals cannot survive without heat energy because their bodies need to heat up so they can do things like moving and eating. If an animal didn't heat their bodies up, they would die.
Why do humans and animals need energy?
Humans and animals need energy to carry out essential functions such as breathing, circulating blood, and maintaining body temperature. Energy is also required for growth, movement, and other physical activities. Cells in the body need energy to produce ATP, which is the molecule used for energy transfer within cells.
Where do we get the energy we need?
We get the energy we need from the food we consume, which is broken down by our bodies to produce fuel in the form of glucose. The glucose is converted into adenosine triphosphate (ATP) through cellular respiration, providing the energy needed for our body's functions.
Why do aerial animals have light bodies?
Because the heavier an object is, the more force is required to lift it off the ground. So, by having light bodies, animals that can fly reduce the amount of energy they need to use to be able to fly.
