The Sun is the primary source of all energy in nearly all food chains. However, some deep-sea ecosystems utilize heat from underwater thermal vents as their primary energy sources since sunlight is virtually nonexistent.
It is the sun.
A source of Energy.
the source for all enery is sunlight
The primary source of energy for almost all food chains is the sun. The usual series is that the sun provides energy to plants that provide to other creatures. Some ecosystems rely on other energy sources however. For instance some deep ocean ecosystems rely on geothermal energy harvested by bacteria.
The sun, it is the main souce of the all food chains , plants get their energy from sun . Without the sun life would not be possible on earth. No plants, no animals
The sun is referred to as the primary source of energy in a food chain, as it provides light and heat for plants to undergo photosynthesis, which is the basis of all food chains on Earth.
The sun is the initial (primary) energy source for life. Ingestion and digestion of a food source is an animal's primary source of energy.
food webs contain many food chains however a food chain shows only one primary source and food webs contain more than one primary source.
The sun is the energy source that provides heat and light for all of Earth's food chains through the process of photosynthesis. Solar energy is converted into chemical energy by plants, which is then transferred through the food chain to sustain life on Earth.
It starts with a primary energy source.
Sunlight
Green plants obtain energy primarily through the process of photosynthesis, where they convert sunlight into chemical energy. Using chlorophyll, they capture light energy and transform carbon dioxide and water into glucose and oxygen. This stored energy in the form of glucose is then passed along to primary consumers, such as herbivores, when they consume the plants. Thus, plants serve as the foundational energy source in food chains.
