Final answer:
Humans and heterotrophs get indirect sun energy through the process of digestion after consuming plants or other organisms that have directly or indirectly obtained energy from the sun through photosynthesis.
Step-by-step explanation:
Humans and heterotrophs obtain indirect sun energy primarily through the process of digestion. Here’s how it works:
- Plants capture sunlight and convert it into chemical energy through a process known as photosynthesis.
- Herbivores, or plant-eating organisms, consume these plants and obtain the energy stored in them.
- Carnivores, or meat-eating organisms, eat the herbivores, and by doing so, they receive the energy that originated from the plants.
- Heterotrophs, including humans, then consume either the plants directly, or the meat of herbivores or other carnivores, and the stored solar energy is released during digestion.
In summary, the correct answer to the question is A) Photosynthesis, which is the initial process that captures and converts solar energy. This energy is then passed along the food chain, and when consumed by heterotrophs, it is released through digestion, satisfying their energy needs.
Therefore answer is A) Photosynthesis.
