When heat energy is transferred between trophic levels. what is always given off to the environment?
heat
What are the basic needs of organisms?
1. evirement 2. cells 3.energy given off by the sun
What type of energy does a fire use?
Chemical potential energy. Fire is a chemical reaction caused by heat Fuel and oxygen (usually) The fuel is combusted exothermically (ie giving off heat) with oxygen which is a chemical reaction. This causes surrounding fuel to heat up a react exothermically with the oxygen, propagating the fire.
When hydrogen burns in oxygen to form water energy is what?
Energy is given off, hence the heat and fire.
What gas is given off in photosynthesis?
The gas given off by photosynthesis is oxygen, plants take in carbon dioxide and generate it into oxygen.
What happens to energy when carbon and oxygen atoms combine?
Energy is given off since it can't be destroyed.
Is energy given or taken off with electrons?
It is given off
Is oxygen given off photosynthesis or respiration?
Oxygen is given off in photosynthesis.Oxygen is utilized in respiration.It acts as last electron acceptor.
What gases are given off when a candle is lit?
carbon dioxide and oxygen are given off
How does the sun give off energy?
It gives off energy by producing oxygen which goes into plants, which produces their energy, then makes more oxygen for our energy, we then produce carbon dioxide
What form of energy is given off by a flashlight?
A flashlight is given off light and heat energy once turn on.
Does energy get released when chemicals react?
Yes, energy is given off when chemicals react. Since energy can be heat or light it is also given off.
What gas is given off by the plant when photosynthesis takes place?
Oxygen is given of
What gas is given off during photosynthesis?
