Final answer:
The source of energy in most ecosystems is sunlight. Plants capture sunlight through photosynthesis and convert it into chemical energy in the form of glucose. Animals in the ecosystem obtain energy by consuming plants or other animals.
Step-by-step explanation:
The source of energy in most ecosystems is sunlight. Sunlight is captured by plants through the process of photosynthesis, in which they convert light energy into chemical energy in the form of glucose. This glucose is then used by plants for growth, reproduction, and other cellular activities. Animals in the ecosystem obtain energy by consuming plants or by consuming other animals in the food chain, indirectly deriving their energy from the sun as well.
