1. Identify the primary source of energy that flows through most living systems The sunlight. Autotrophs use sunlight to make their own food. Organisms that can’t make their own food consumed the food molecules made by autotrophs, eat autotrophs or eat organisms that consumed autotrophs.
2. Explain how an organism’s metabolism is related to Earth’s carbon cycle. An organism’s metabolism is related to using energy to build organic molecules which contain carbon or breaking down organic molecules in which energy is stored. Because of this, an organism’s metabolism is a part of the Earth’s carbon cycle. This cycle make carbon compounds continuously available in an ecosystem and deliver chemical energy to organism living within that ecosystem
3. Describe how energy is released from ATP.
ATP is made up of an unstable chain of 3 phosphate group because they are all negatively charged and thus repel each other. The energy that was stored is released during the breaking of the 3rd bond. This energy can be released as heat or power in cell in order to help perform chemical activities. ATP can be used to contract muscle cell, actively transport a protein or help make more ATP.
4. Analyzing Patterns Explain how life involves a continuous flow of energy.
The law of conservation of energy states that the total amount of energy is an isolated system remains constant. The consequence of this law is that energy cannot be created nor destroyed. Energy can be converted or transformed into another form of energy. We can’t create more energy. A certain amount of energy will always be lost, usually as heat, to the environment. Therefore, when we use glucose and other products to maintain our bodies, we generate heatas a “waste product”. Heat is also lost at each step as we go up the food chain, until all the energy trapped by plant is liberated as heat. Thus, energy does flow through life, or a system. At one...
