Organisms utilize ATP in three main ways: 1) as a source of energy for cellular processes such as muscle contraction and active transport, 2) for biosynthetic reactions to build molecules like proteins and nucleic acids, and 3) for signaling pathways to regulate various cellular activities.

Organisms use ATP for energy transfer, chemical reactions, and cellular movement. ATP provides energy for processes like muscle contraction, protein synthesis, and active transport across cell membranes. It is also used in signaling pathways and maintaining cell structure.
Organisms can adapt by changing their behavior, such as seeking shelter or moving to a different location. They can also physiologically adjust by changing their metabolic rate or developing features like thicker fur or insulation. Some organisms can undergo hibernation or enter a dormant state to survive extreme temperature changes.
Organisms can interact through competition for resources, such as food or territory. They can also interact through predation, where one organism consumes another for energy. Lastly, organisms can engage in mutualistic relationships, where both benefit from the interaction such as in the case of pollination between flowers and bees.
Viruses and bacteria are both microscopic organisms that can cause infections in living organisms. They are different from each other in terms of structure and how they reproduce, but they can both cause diseases in humans, animals, and plants.
Early organisms responded to rising oxygen levels in different ways. Some adapted to thrive in the new oxygen-rich environments by evolving mechanisms to utilize oxygen for respiration and energy production. Others faced challenges as oxygen became toxic to them, leading to their decline or extinction. This event, known as the Great Oxygenation Event, had a significant impact on the evolution of life on Earth.
