What else can I help you with?
Where does most of the energy for life processes originally come from?
Most of the energy for life processes originally comes from the sun. Through the process of photosynthesis, plants and other autotrophic organisms convert sunlight into chemical energy that is then used by heterotrophic organisms for their own life processes.
How is the energy not used for life processes lost?
The energy not used for life processes is lost as heat. This excess energy is released as heat when organisms metabolize food for energy. This heat is then dissipated into the environment.
Why is energy important to organisms?
Energy is essential for organisms to carry out their life processes such as growth, reproduction, and movement. Organisms need energy to maintain their metabolic functions and to provide the necessary chemical reactions for survival. Without energy, organisms would not be able to sustain life.
How much of the food energy that is taken by an organism is used for its own life processes?
Producers use about 90 percent of the food energy they make during photosynthesis for their life processes.
Which is a characteristic that all organisms share?
All organisms share the characteristic of requiring energy to carry out life processes. This energy is obtained through activities like eating, photosynthesis, or chemical reactions. Without energy, organisms would not be able to grow, reproduce, or maintain their internal processes.
What are three of the life procsses that living organisms do?
Three life processes that living organisms do are obtaining and using energy, responding to the environment, and reproducing to ensure the survival of their species.
How much of the food energy that is taken in by an organism is used for its own processes?
Producers use about 90 percent of the food energy they make during photosynthesis for their life processes.
What is the energy needed for all life processes is measured in?
The energy needed for all life processes is measured in units of ATP (adenosine triphosphate). ATP is the energy currency of the cell and is used to fuel various biological processes in living organisms.
Why organisms must have food?
Because food is a source of energy and it also supplies cells with oxygen
How do the laws of energy transformation relate to energy used by organisms?
The laws of energy transformation dictate that energy cannot be created or destroyed, but only transferred or transformed. Organisms obtain energy from their environment through processes like photosynthesis or consuming other organisms, and then use this energy to carry out essential functions like growth, reproduction, and movement. Energy is constantly being converted within organisms to sustain life processes in accordance with the laws of energy transformation.
Does all life need energy?
Yes, all living organisms require energy in order to carry out essential functions such as growth, metabolism, and reproduction. This energy is usually obtained from sources like food or sunlight through various biological processes like photosynthesis or cellular respiration. Without energy, living organisms would not be able to sustain life processes.
Organisms can't create the energy they need to live they must capture it from the environment true or false?
True. Organisms cannot create energy; they must obtain it from their environment. This energy is typically captured through processes such as photosynthesis in plants or cellular respiration in animals. These processes convert environmental energy sources into forms that organisms can use to sustain their life functions.
