the sun
The ultimate source for living thins is the sun. This is because the sun provides things on the absolute bottom of the food chain with food. They are then used as food for the next living thing on the food chain. Things on the bottom of the food chain are called producers. They perform photosynthesis to convert the suns light into useable energy. Organisms the can create their own food are called autotrophs.
Plants are the ultimate source of energy because they undergo photosynthesis, converting sunlight into chemical energy in the form of glucose. All organisms, directly or indirectly, rely on plants for energy through the food chain. Without plants, energy transfer within ecosystems would not be possible.
The ultimate energy source for all food chains is the sun. Plants use sunlight to photosynthesize, converting solar energy into chemical energy that is passed on to herbivores when they consume the plants. This energy then moves up the food chain as animals consume other animals.
The ultimate source of energy in any ecosystem is the sun. Solar energy is converted into chemical energy through the process of photosynthesis by plants, which then gets transferred through the food chain to all other organisms in the ecosystem.
the sun
The ultimate source of energy for living systems on Earth is the sun. Plants and some microorganisms use sunlight to perform photosynthesis, converting solar energy into chemical energy stored in organic molecules. This energy is then passed through the food chain as organisms consume other organisms.
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.
plants
The ultimate source of energy for terrestrial ecosystems is sunlight. Plants capture sunlight and convert it into chemical energy through photosynthesis, which is then passed on to consumers in the food chain. Without sunlight, photosynthesis cannot occur, and the ecosystem would not have the energy needed to sustain life.
Producers
The sun is the major source of energy for the food chain through a process called photosynthesis. Plants, algae, and some bacteria capture sunlight to convert it into chemical energy that is then passed on to consumers in the food chain.
