Most of our source of food comes from corn, wheat, and rice. Almost all food today has at least one of these ingredients
Most plants are autotrophs, meaning they create their own food source.
The food part i guess
The initial food source for most terrestrial ecosystems is typically plants. Plants produce their own food through photosynthesis, which forms the base of the food chain for animals and other organisms in the ecosystem.
Phytoplankton.
Most ofhe green plants can make food For making food the green plant needs chrolophyll if it is present then the plant can make food
the sun is the main source of energy for plants since it helps the most with the process of photosynthesis photosynthesis is the process of a plant making it's food which means it does not rely on other organisms for food
Most plants use photosynthesis to create glucose, their food source. However, some plant species are parasites and feed off of others.
The ultimate source of energy for most organisms is the Sun. This energy is captured by plants through photosynthesis, where they convert sunlight into chemical energy stored in sugars. Other organisms then consume these plants (or organisms that eat the plants) to obtain energy and nutrients.
most of its water comes from food it eats, in yards it can get it from any water source, plants pools etc
Plants are a major food source (they are autotrophs and can produce food through photosynthesis), they produce the oxygen we breath (through photosynthesis), and they help climate control for us and other animals on this planet (by returning water vapour to the atmosphere and carbon sequestration. They are the primary source of all food for "consumers" and "secondary consumers". They are also directly and indirectly the source of most food, fuel, medicines and (natural) building materials. With out plants earth would be a mostly dead planet.
Most, if not all plants, fish, or any other food that is not a significant fat/blubber source.
Most background radiation comes from natural sources, while most artificial radiation, plants absorb radioactive materials from the soil and these pass up the food chain.
