It provides it because the air or oxygen from the plant helps us and other living animals live. Without it we could die. It would be very true to say that we depend on it. But I will say that is not the best answer. Starch is part of the plant. When a animal or person eats these plant parts they are also consuming the extra energy from the starch. For example when you eat salads you get energy from the lettuce. But sugar can be changed into fats.
it gives you energy photosynthesis
you can burn plants, and fire can be used to boil water to run a turbine. with photosynthesis: photosynthesis makes glucose, which is used for energy in animals and people that eat the plants
Many plant cells produce energy through Photosynthesis.
People can get energy from sunlight through a process called photosynthesis, which is carried out by plants, algae, and some bacteria. During photosynthesis, these organisms convert sunlight into chemical energy in the form of glucose, which can be used for various cellular functions and to produce ATP, the energy currency of the cell.
Chloroplasts are only found in plant cells. If they were in animal cells, people would be green.
A plant cell takes in energy from sunlight, goes through photsynthesis, and releases oxygen. That oxygen is used by an animal cell (people and animals), so that it can create energy, and release carbon dioxide. That supplies the plant cell with carbon dioxide, so that the animal cell gets even more oxygen. And so on, and so on.
The sun provides heat to people on Earth through the process of radiation, where electromagnetic waves carry heat energy to our planet. This energy is then absorbed by the atmosphere, land, and oceans, warming them up. The sun also provides energy for photosynthesis, which converts sunlight into chemical energy that plants use to grow. Humans obtain this energy by consuming plants or animals that have eaten plants.
Yes, Fossil fuels are plants that have died millions of years ago and degraded into their elemental components over the course of that time. Plants create their energy from photosynthesis, thus those long dead plants had at one time created that energy by photosynthesis.
Heat energy comes from the sun because when the sun is out people would have heat around the place.!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Plants need chlorophyll because that is what allows them to convert sunlight to energy they can use in their metabolism. People do not use chlorophyll, and so don't have it, because as animals we do not convert sunlight directly to energy. We eat plants, or other animals that eat plants, and use their energy.
People have been burning wood for centuries to provide themselves with heat energy.
Plants convert electromagnetic radiation in the optical spectrum to energy through photosynthesis --> Herbivores/omnivores eat the fruit/leaves of the plant --> Carnivores eat the herbivores/omnivores --> Previous two animal types die, once rotted nourish the plants with much needed fertiliser --> plant converts..
