Point out that both processes use energy to produce carbohydrates-energy-rich compounds that organisms can use to power life processes. Energy in Biological Systems Students may think that energy is formed, or created, by the processes of photosynthesis or chemosynthesis.
There is ONE main source of energy on Earth, and that's the sunlight. This indirectly powers almost everything on Earth. The other sources of energy (geothermal energy, related to radioactive decay inside the Earth; and tidal energy, related to Earth's rotation) are of much less magnitude, and are not used to any significant extent by life on Earth.
Solar energy,
Chemical energy (ATP)
sunlight! duhhr!
The sun and the sunlight are the main things for all living things.
ADP and ATP are used by living things to sore and supply energy. The energy originally comes from the Sun.
Living things need energy to do stuff like grow, breathe, walk around, dress themselves, sleep, procreate and do their homework. They get it by eating or by soaking up soil and sunlight. If they don't, they soon cease to be living things, and they no longer need to worry about energy.
save the living things
Most things have thermal energy. Thermal energy is comes from heat and therefore anything that can generate heat has thermal energy. All living things have thermal energy.
sunlight
The sun, respiration, photosynthesis and food are all sources of energy for living things.
The Sun.
Renewable sources of energy
The sun and the sunlight are the main things for all living things.
The sun is the ultimate source of energy in living things since plants use sunlight to make glucose and other animals use the glucose by eating the plants.
Without the intake of energy, the default is that things decay (entropy). Living things, which are not closed systems, have to take in energy from outside sources in order to keep their molecules organised into a functional frame for life.Once living things die, then they cease to take in energy and things naturally decay or disorganise themselves.
producers- a living thing that gets its energy from the sun ex. plants primary consumers or herbivores. Are living things that get their energy from plants. ex. rabbits secondary consumers or omnivores. Are Living things that get their energy from either plants or other animals. Ex. A bear tertiary consumers or carnivores. Are living things that get their energy from other animals only ex. a mountain lion decomposers. Are living things that break down dead organisms. ex. Mushrooms Note not to be confused with detrivores living things that eat dead things.
carbohydrates
Living things get energy from food . Producers make their own food , with the aid of Sunlight . Consumers depend on the producers for their food . Secondary Consumers depend on the primary consumers for their food . Decomposers depend on the dead bodies of consumers and producers for food . So simply , Energy flows from Sunlight to plants to consumers to secondary consumers to Decomposers . That's how living things obtain their energy .
Energy is required for living things because they have to have energy to do every other characteristic of life. Living things obtain energy by making it themselves or eating other organisms.
Sunlight and, at the Ocean bottom at heat vents, hydrogen sulfide are both use as sources on bio-energy.
