A tolerance curve is the range of conditions within which the organism can live and function.
Imperialism led to conflict over colonial resource, labor, and markets (APEX)
An organism that uses energy to produce its own food supply from inorganic compounds is called an autotroph (within a food chain, it is a producer).
Abnormal conditions within the tissues of an organism. This can range from infectious diseases to cancer to degenerative issues.
Energy is passed through an ecosystem through the organisms within it. The sun produces all energy within an ecosystem. As the sun produces energy, it is absorbed by the producers (plants) through photosynthesis. These plants are then consumed by other organisms. The energy decreases by 10% as it is being passed from organism to organism. For example, if grass is the producer it absorbs 100% of the energy from the sun. This grass is then consumed by a small herbivore, which receives only 10% of the original energy. Where does the energy go? The energy has been lost through heat, and it was also used to live, grow, and reproduce.

A most basic answer: living organisms must use energy to maintain homeostasis.Homeostasis is the "balance" of our body--we are kept within a very strict and small allowance of our internal environment. This includes our pH, temperature, fluid levels, etc. If any of these things change, the body must spend energy to get it back within that allowable range for us to live. That isn't to say the body doesn't spend energy if things are within range--it is constantly using energy to KEEP things in that range (not just fix the ones that wander out).How it uses the energy to maintain homeostasis is a very long and varied answer. There are hundreds of ways for hundreds of situations.
simple organic molecules are not necessary for the life process of an organism.
