Because the cells can only use energy in form of ATP.
Its like you can't run a diesel truck on petrol.
The correct answer is - 1) inverted pyramid, with a narrow base representing a small number of young individuals.
The populations that are decreasing are usually population in countries that are highly developed. The conditions for living are excellent, the medical care on high level, life expectancy very high, but the birth rates very low.
In this type of conditions, there's smaller and smaller number of young individuals, with the middle aged population being much bigger, and the older population being constantly on the rise. This will give the age-structure histogram a reverse shape than what it is supposed to have, it will be similar in appearance like a inverted pyramid, meaning that the population is aging and that it will be constantly on a decline in the future.
False, that is one thing many people were always doing, back then.
Answer:
Legume crops improve soil health, they add nitrogen and organic matter to the soil and reduces potential erosion and leaching loss. Legumes may reduce the energy footprint of cropping systems by reducing the need for nitrogen fertilizer, and improve the stability and health of agro-ecosystems.
Plants and certain microorganisms use photosynthesis to create compounds such as carbohydrates. It's an endothermic (heat-inducing) chemical reaction that converts carbon dioxide to sugars using sunlight. Sugars are used by the cell as an energy source as well as a building block for other molecules. Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.
